Laser Color Printer Strips When Printing

Printing streaks. what to do?

Over time, any device can significantly reduce print quality or even block this function, giving a warning in the need for repair for a variety of reasons. Let’s consider the possible problems in which the printer prints in stripes, but does NOT refuse to work.

Of course, for laser and inkjet printers, malfunctions and methods of their elimination differ significantly.

Stripes when printing with an inkjet printer

This picture can be obtained with poor ink supply. The first thing to do is stop printing and refill the cartridges. In the absence of paint, even a nozzle test cannot be performed without the risk of burnout of the nozzles.

Cleaning nozzles

Is everything okay with the ink tank, and the printer still “streaks”? Now you can check the nozzles. If there are gaps on the test page, the nozzles are really clogged and need to be cleaned programmatically.

When several attempts do NOT produce the desired result, manual cleaning is required. You can read about this in the article. How to flush the Canon PIXMA print head. Cartridges with a built-in nozzle plate are soaked in a similar way.

This was the most frustrating situation, requiring patience and time to troubleshoot. You may not be so bad.

Align printheads

Are the cartridges full, the nozzle test is excellent, but the print is blurry, streaks, fuzzy lines? Another Possible Cause Of GHG Out Of Calibration.

If you took your printer somewhere or simply moved it badly, shaking it hard enough could cause the carriage to move slightly. Select the “Align Print Heads” function in the service program and follow all recommendations.

Cleaning the tape and encoder disc

The next defect: white stripes at equal distances from each other. Their width can be different and depends on the degree of contamination of the encoder disk. This part is located on the left of the paper feed shaft, it is a circle of transparent material with markings. If the dashes are covered with dust or dried ink, the Corresponding Sensor cannot see them, therefore the paper is not positioned correctly. Wipe the disc with a soft cloth dampened with a special cleaning liquid or Mr. Muskul window cleaner containing ammonia.

Important: you cannot use acetone to clean the encoders. there is a risk of removing the markings.

The positioning of the carriage is answered by the encoder tape and the corresponding sensor. With dirty markup, some of the text is shifted to the side, which is repeated at regular intervals throughout the page. This transparent strip with dashes is located along the main paper feed shaft. Wipe it carefully so that it does not slide off the mounts, because half of the printer may need to be disassembled to replace the part.

Stripes when printing with a laser printer

To complete the picture, watch the video on the principle of using a laser beam in a printing device.

Now let’s look at Possible malfunctions of cartridge parts, in which the printer prints stripes of different widths, lengths, definitions and colors along or across the page.

Toner out

In the vast majority of cases, “striped printing” on a laser printer is associated with the condition of the cartridge. The most harmless thing here is white stripes along the entire length of the page, the width of which increases with each copy. The only reason is toner out.

Important: Do not shake the cartridge in attempts to retrieve a few more pages. If the toner is used up, it will not magically appear even from hitting the table, but the waste will surely spill out of the sump. Waste printing will significantly shorten product life.

Damage from dropping the cartridge

Sealing gums, which are designed to trap powder, may NOT withstand a strong impact: toner spills at the damaged area and leaves marks on the page.

Longitudinal stripes can be of different widths and be located anywhere. Repair required.

Waste Toner Box Overflow

Dark dots, dashes or specks are visible along the letter, which, as you continue to print, enlarge and merge into a strip. In most cases, this defect is caused by spilled toner from an overfilled hopper. Reason: poor cleaning. Need refueling and preferably use the services of a second service center.

The image drum is worn or damaged

An intermittent black line appearing at the edges of the page, the pattern of which is accurately repeated several times, indicates that the drum is worn: a thin layer of photosensitive varnish is erased over time by the edges of the paper.

Mechanical damage to the drum surface by dust, paper clips and other foreign objects is manifested by black dots or dashes scattered across the printed page in a chaotic (at first glance) disorder. However, upon closer examination, it is noticeable that the pattern of defects on the sheet is repeated several times.

With further use, the surface of the drum is even more damaged by the squeegee (which, in turn, also becomes unusable) and toner particles, minor defects increase and merge into black stripes. You cannot print any further, as a damaged squeegee DOES NOT remove the powder completely, and excess toner spills into both the cartridge and the printer. Urgent recovery required.

Dispensing blade

The correct filling is of great importance. An unevenly installed dispensing blade passes more toner than necessary (blue stripe in the illustration).

Contamination of the blade during operation leads to a decrease in the gap in certain places and a decrease in the amount of toner passed through. On printing, this will appear as faint (with heavy contamination. white) longitudinal stripes.

Pins for drum and primary charge roller

The following figure shows the result that powder spilled during hopper filling remains inside the cartridge body. During use, the toner has clogged the imaging drum (gray stripes) and primary charge roller (black across the page) contacts. In addition, the drum surface began to wear out (strip on the right edge of the sheet).

Printing with an overfilled waste container can cause similar damage. In addition to the above, toner residues falling into the housing may damage the surfaces of the primary charge roller.

Almost always, defects from a malfunction of several parts are visible on the sheet. It is not easy to figure it out for non-professionals. It is advisable to show the specialist the printed page in order to correctly determine which parts of the cartridge need to be replaced, and decide whether the printer needs preventive maintenance or even urgent repair.

Why do streaks appear on the printer when printing?

Any printer, be it laser or inkjet, in the process of operation comes to such a stage of its work when the print quality deteriorates. Printed pages become dull, horizontal or vertical stripes appear on the paper, the image is printed with gaps (fills in places), etc. All these troubles can appear for various reasons, which depend on the printing technology used in the devices. For a laser printer, these are problems with a cartridge or drum, and for an inkjet, if it prints with stripes. malfunctions in the print head, interruptions in ink.

“Striped” defects in inkjet printers

There are not so many reasons for the appearance of “banding” on the sheet that came out of the printer.

But, if before the appearance of this defect, your unit was printed with high quality, then in most cases, the problem is fixable at home, and you can do without going to the service center.

Checking ink levels

First of all, check the ink level on the inkjet printer. To determine the ink level, you can use the software, namely the utility that comes with any printing technique. For example, to determine how much the cartridge has run out of HP equipment, you need to run the program designed to manage the machine and select the tab “Estimated ink levels.” The utility window is shown in the figure below.

For Epson units the window will look like this:

When the ink level in the cartridge reaches zero, it must either be refilled or changed to a new one.

If CISS is connected to the printer, this program will be useless. The ink level is easily determined if you look at the transparent CISS containers. If there is enough ink in them, then you should check the plume through which ink enters the cartridges. It should not contain kinks, the loop tubes should NOT be pinched by anything, and there should be no air s (small areas with air) in them. You should also check the air filters on the CISS containers. If they are clogged with dust or ink, then there will be no air leaks in the container, and ink from these containers will stop flowing to the print head, which will cause streaks during printing.

Cleaning the printheads

It is very important for inkjet printers that there is no downtime. Otherwise, due to a long pause, the ink in the print head dries up and clogs up the nozzles. holes through which ink is sprayed onto the paper.

But for most devices, it takes 1 to 3 weeks for the ink to dry in the nozzles. In any case, you need to regularly turn on the device so that it can “blow” the nozzles with ink.

In modern printers and all-in-one printer, the manufacturer has provided the ability to clean the print head by means of the device itself, with the introduction of a proprietary utility. For example, for an HP device, this feature is called “Clean Cartridges”.

For Epson printers This function is called “Cleaning the Print Heads”. Also, this software allows you to make a preliminary check, which allows you to determine from the printed impression whether the nozzles are really clogged. This function is useful in order to save ink, since when cleaning the printheads, an increased consumption of ink occurs: it is with ink that the nozzles are washed.

For Canon devices, in order to clean the head, in the utility window, you need to click on the “Cleaning” item, or “Deep cleaning”. its more advanced type, with a large consumption of ink.

If hardware cleaning does not help, then you will have to resort to manual flushing of the printheads, as shown in this video.

If the jet head is built into the cartridge, then it is recommended to soak the nozzles in the Mr. Muscle glass cleaner for at least a day. It is desirable that the liquid be green or blue. Soak the nozzles so that the detergent does not get on the electrical contacts. After soaking, gently blot the nozzles with a tissue, insert the cartridge into the printer, and start the standard cleaning procedure described above.

It is not recommended to soak and rinse the inkjet head from an Epson printer at home, as it is very “capricious” and can easily become unusable. The price of a new head is comparable to the price of a new printer. Therefore, if there is a suspicion that the nozzles are dry, it is better to contact the service center.

Problems with encoder tape and disc

Also, a prerequisite for the fact that a white line appears during printing, which is repeated at the same distance, may be the presence of clogging on the encoder disk. It is usually located on the left side of the machine on the paper feed shaft. The disc is made of transparent plastic and has special markings.

When there is dust, paint or other dirt on the disc markings, the optocoupler sensors are NOT capable of reading the information correctly, and the paper positioning is incorrect. You can also use the Mr. Muscle tool to clean the disc. It is important that this product is intended for glass cleaning and contains ammonia.

The carriage into which the cartridges are inserted is positioned along the encoder tape. It is a transparent plastic strip with strokes applied to it. It is located near the back wall (inside the device).

If dirt gets on the tape, then the correct positioning of the carriage is lost, and the text or image when printing is shifted to the side, at regular intervals. Wipe this tape with the same product as the encoder disc. Just be careful during this procedure. If the tape comes off the fasteners, then in order to install it in place, you will have to disassemble half of the device.

Why does a laser printer print in stripes?

Before looking for the reason why the laser printing machine stripes, it is necessary to have at least a minimal level of understanding of the unit’s device. It can be clearly seen in the following figure.

When printing on a laser printer, streaking can be caused by the following reasons:

  • Damage to the drum unit;
  • Violation of contacts between the magnetic shaft and the drum unit;
  • Out of toner;
  • Damage to the magnetic roller;
  • Cartridge leak
  • Overflow waste bin.

Drum damage

The drum is an aluminum shaft, which has a special coating that is sensitive to optical radiation. Only the outer layer is sensitive to laser radiation, which becomes thinner over time and in some places is erased.

Even if wear is not visually detected, the thinning of the active layer still affects the print quality. In this case, black streaks appear at the edges of the sheet. As the active layer wears on the drum, the stripes will expand.

Although there is a method to restore the active layer to the drum, it is not effective enough. The best way out of this situation is to replace the part with a new one.

Lost contact between the magnetic roller and the drum unit

If a sheet comes out of the printer with horizontal stripes located at the same distance from each other, then this is a sign of poor contact between the drum and the magnetic roller.

Such a nuisance occurs when toner spills or the waste bin is full. Also, this defect can occur after unqualified refilling of the cartridge or wear of the shaft, squeegee, photoconductor. The problem is solved by replacing the failed units or high-quality refilling of the cartridge.

Toner out

The fact that the toner cartridge has run out can be understood if white streaks of different widths appear on the sheet.

What if the toner runs out? The answer is obvious: replace or refill the cartridge.

Damage to the magnetic shaft

The main purpose of the magnetic roller is to transfer toner to the drum unit. Since the toner contains abrasive particles, it is because of them that the magnetic roller is worn out.

If the magnetic roller is damaged, the following printing defects become noticeable:

  • White voids appear on the sheet;
  • Gray blots appear, evenly spaced on the paper;
  • Faint print;
  • Uneven image fill.

Also, with damaged magnetic shafts, horizontal wavy stripes may appear.

This problem can be solved only by replacing the shaft.

Cartridge leak

The fact that the tightness of the cartridge is broken is indicated by vertical stripes, located chaotically, and each time in a new place.

You want to remove the cartridge from the machine and check if toner is spilling out of it. If this is the case, then you should check this element for mechanical damage, whether the sealing gums are well inserted, and not allowing the toner to spill out. If cracks or other irreparable damage are found, the cartridge needs to be replaced.

Waste bin is full

The cartridge contains a squeegee that removes unused toner. The latter is disposed of in a special container called a waste bin. This compartment is usually cleared when you replace the cartridge. If the hoppers are not cleaned, it will overfill with toner, which will spill out. The following figure shows the effect of overfilling the waste compartment.

The squeegee looks like the figure below.

To get rid of the print defect, you will need to clean the waste bin or replace the blade.

Why the printer prints in stripes and how to fix it

In Printer Operation The most common printing defect is streaking on the paper. They can be narrow, wide, horizontal or vertical, more Blurred or very bright, colored or Monochrome, with or without spaces. In this case, the printed document does not color any stripes at all. After all, this is a serious defect, which is not always easy to get rid of. Therefore, let’s find out why streaks appear on paper when printing and find out how to fix this problem.

What causes streaks when printing in an inkjet printer?

There are several typical reasons that lead to streaking on paper. over, they are different in inkjet and laser printers. To begin with, let’s talk about why an inkjet printer can “strip”:

  • Low on ink.
  • The ink has dried or thickened inside the printheads (usually due to the fact that the device has NOT been used for a long time).
  • The integrity and tightness of the cartridge is broken.
  • Deformation of the shaft has occurred (often associated with a long service life of the device).
  • Defective Printhead. She can be airy. Or out of order / pinch the loop itself. Most often, with such a breakdown, horizontal stripes are observed on the sheet.
  • The elements of the esponder are dirty or damaged. Is it the tape itself or the sensor.

These are the most common reasons. However, printing streaks may also appear as a result of other problems that are NOT listed above.

Troubleshooting Flowchart for Inkjet Printer

We figured out why the printer prints in stripes. Now let’s talk about how to diagnose and eliminate all of the above malfunctions, which are often the reasons for the appearance of stripes on paper. To make it easier for you, we recommend sticking to the following algorithm:

  • Check the ink levels first. To do this, use the printer’s control panel, where almost every model has a similar function that allows you to check the remaining toner. For example, on HP devices, it is located under the Estimated Ink Levels tab. Click on it. the result will be shown on the display. If CISS is used, then you can visually check the remaining ink. Naturally, if the toner runs out, then Install a new cartridge or refill the old one.
  • Replace the cartridge even if it is leaking. It is not difficult to check the integrity of this part. Pull out the cartridge and shake it a little over the table, on which you have spread some paper or newspaper beforehand. See the spilled toner? Then the cartridge must be replaced. If the part is airtight, then we put it back and continue diagnostics.
  • Now you need to check the CISS loop. Pay attention to its integrity. Make sure it is NOT pinched anywhere. Although it can be difficult to diagnose a loop failure on your own. It is also not easy to replace it. Therefore, we recommend that in case of such a breakdown, contact the service center.
  • You have made sure that the CISS loop is fully operational. After that, it would be nice to inspect the air hole filters. They often become clogged with ink and stop allowing air to pass through. The same, forming stripes when printing. If they get dirty, then it is best to replace them with new ones.
  • Does the printer strip anyway? And white and unprinted stripes appear with an image shift? This means that it is necessary to clean the encoder tape. This is a translucent film along the carriage. All you need to do is take a lint-free cloth, soak it in the cleaning solution, and wipe the tape. Then let it dry. Did not help? Do the streaks keep appearing when printing? Moving on to the next item.
  • You will have to clean the print head. It can be airborne or contaminated. It should be remembered that in inkjet printers the head can be located both inside the cartridge (Canon, HP), and separately, as an independent part of the device (Epson). With the first option, everything is pretty simple. It is enough to replace the cartridge. However, if the head goes separately from the cartridge, then replacing it will be expensive. It is more expedient to clean the print head. This is done programmatically:
  • Insert clean paper into the printer tray.
  • Open the management utility or go to the specialized device settings center.
  • Find the section “Service” or “Service”.
  • We start cleaning the printheads and checking the nozzles (nozzles).
  • If the problem is not solved, then we repeat the operation 1-2 more times. Don’t forget to wait about 2-3 hours. Then we check if the printer has stopped printing in stripes.

However, it is not always possible to clean the printhead programmatically. For example, this procedure is meaningless on an inkjet all-in-one printer Canon Pixma MG2440. This model has a head cleaning pump. Therefore, you can manually remove dried ink. For example, using chemical cleaners.

Didn’t cleaning the printheads and manual flushing with fluids help? Then, most likely, this part is out of order. Broken printheads are common. The most common reason is careless handling of this mechanism during removal / installation. In addition, if you print a lot on a printer or an all-in-one printer, then the malfunction of the head is simply due to normal wear and tear. Which exit? The answer is obvious. part replacement. The easiest way is if it is built into the cartridge. But for most printers (for example, Epson), the head is placed separately, and its price ranges from 50 to 80% of the cost of a new device.

Have you followed the above algorithm, but the inkjet printer continues to strip? Hence, it is worth contacting the service center for help. Or even seriously consider buying a new device.

Why does a laser printer print in stripes??

Stripes can often be observed when printing on laser printers. What can be a prerequisite for the appearance of such a malfunction? The list is quite long:

  • Ink level is low.
  • Depressurization of the cartridge.
  • Drum damaged / defective.
  • The magnetic roller is damaged or a foreign object has fallen on it (with such a malfunction, in 80% of cases, information comes out of print with a black stripe along the edge or side).
  • Waste Toner Hopper Full.
  • Loose toner metering blade.
  • Lost contact between drum and magnetic roller

over, this list can be continued for a very long time. But we named the most common reasons, and therefore we will move on to how to eliminate the printing failure and, finally, forget about sheets with a strip.

Getting rid of streaks when printing on a laser printer

When diagnosing problems in the operation of a laser device, we recommend that you pay attention to the specifics of the appearance of stripes. This will help you understand what kind of malfunction caused the print defect.

  • Let’s say a laser printer prints a strip in the middle. This usually indicates that toner is low. over, the less ink in the cartridge, the wider the band. If you check and make sure there is enough toner, then the supply system is faulty. Better to contact the service center.
  • The stripes are made up of small dots. In 90% of cases, such a printing defect is due to the fact that the hopper is full, which collects the rest of the toner. What should be done in such a situation? Of course, she will clean the bunker. By the way, it is desirable to carry out this procedure every time the cartridge is refilled. Sometimes streaks of small dots also occur due to the fact that the metering blade is incorrectly installed. So don’t forget to check it too.
  • Unprinted, white and fairly wide stripes on the sheet. There may be several reasons. For example, toner is low. Or, a foreign object (paper clip, piece of paper or tape, coin, etc.) has fallen on the shaft. In this case, getting rid of the stripes is not difficult. It is enough to remove the foreign body.
  • Faint black stripes stretch across the sheet? It doesn’t bode well. This is often caused by wear on the magnetic shaft. You can correct the situation by replacing the assembly or cartridge.
  • Dark stripes on one or both edges of the sheet. They indicate wear or damage to the drum unit. Most likely, you will have to change the part. The fact is that the sensitive layer in the drum is erased over time, it is problematic to restore it, to put it mildly.
  • Irregular stripes fill the entire sheet (looks like a background). Poor quality toner may have been used when refilling the cartridge. Another potential cause of this print defect is a dirty magnetic roller or printer optical system.
  • Horizontal and nearly equidistant stripes. Most often, the problem lies in poor contact between the magnetic roller and the drum. Perhaps toner has spilled, the ink waste bin is full, or a poor-quality cartridge refill is to blame. It is recommended to clean the shaft contact and other surfaces. If this does not help, then it makes sense to install a new cartridge.

As you can see, nothing difficult to comment on. At the same time, it is often easier and faster to eliminate streaks when printing on a laser printer than on inkjet printers. If the device produces stripes on printed paper, then you just need to pay attention to their shape and appearance area, and also check:

  • Toner level;
  • Serviceability of the drum unit;
  • Cartridge status
  • Dispensing blade position;
  • Fullness of the mining bunker.

Printer Prints Stripes. Troubleshooting Guide Inkjet printer prints in stripes

Possible causes of the problem:

  • Low on ink.
  • Printhead nozzles (PG) clogged with dried ink.
  • Air is trapped in the print head.
  • Malfunction of the mechanics or electronics of the printer itself.

Color inkjet printer strips

Ink level problems. What can be done:

Sins of ink level follow when the printer starts to print streaks on photos or documents unexpectedly. It’s not about ink if: you recently changed or refilled the cartridge, there was a malfunction (for example, the paper was jammed and you pulled it out of the printer) or something happened to the printer itself (it was turned over, dropped, or was in the cold for some time ).

laser, color, printer, strips, printing

Check ink levels programmatically and replace cartridge.
Select Maintenance or Service from the printer control menu. Run an ink level check. If there is little or no more. replace cartridges.

Visually check the ink level in the ink tank (if you are using one) and refill.
In refillable cartridges, the actual ink level may NOT coincide with the meter reading, so remove the cartridges and visually check the ink level. If there are very few of them left, the cartridges should be refilled.

Check the efficiency of the CISS (for those who have it installed)
Make sure there is enough ink in the donor bottle. Check if something is interfering with the flow of ink through the plumes, as well as at what height the donor containers are (sometimes it makes sense to raise them). If air gets into the plumes, it should be removed from there. For details, see the instructions for removing air from CISS loops for Epson. Or instructions for Select HP and Canon models. If the plume is forgotten with dried ink, it should be cleaned or replaced.

Change old ink (for owners of refueling complexes and CISS)
It is unlikely that the streaks when printing “suddenly” appear due to old ink, but the expiration date should still be checked.

Printhead problems. What can be done:

You should pay attention to this item first of all, if the stripes during printing appeared after a long idle time of the printer (they did NOT print for more than a week, and it was NOT preserved) The occurrence of problems with GHG may also be preceded by manipulation of the printer, transfer from place to place, change or refilling of cartridges, attempts to “get inside” without proper preparation.

Runs “Nozzle / Nozzle Check”
In the printer control menu, select the item “Nozzle check” or “Nozzle check” (depending on the printer model). A printout of a test page will help determine the cause of the problem and possibly even fix it using software.

Runs “head cleaning”
In the printer control menu, select the “Head cleaning” or “Nozzle cleaning” item. You can run it several times, but always with pauses of 5-15 minutes. If several of these procedures did not help, proceed with cleaning with service fluid.

Flush the printhead (PG is located in the cartridge)
If you have a two-cartridge printer, then the PG is on the cartridge. Try to rinse it according to the instructions (point 1), if it did NOT work, then the cartridge will have to be replaced.

Cleans the print head with service liquid (the PG is located in the printer)
The method is relevant in case of severe clogging or air ingress into the print head. Use a syringe, cleaning fluid, and lint-free wipes to thoroughly clean the nozzles.
Step-by-step instructions can be found in the detailed instructions for cleaning the steam generator.

Other printer malfunctions.

In the vast majority of cases, the problem of streaking during printing is associated with the ink and print head, but sometimes with malfunctions in the printer mechanics. In this case, we recommend that you contact the service specialists, since an attempt to “get inside” without special knowledge can lead to permanent damage to the device.

Problem with reading the encoder tape.
Encoder (raster) tape. A strip stretched inside the printer with strokes, with which the device determines the position of the print carriages in space. By chance, ink or dirt can get on the tape, because of which the printer will stop “seeing” some of the strokes and will begin to “slip” part of the sheet when printing. As a result, one or more longitudinal (vertical) stripes will appear on the page.
The problem, in this case, is solved by cleaning the tape from dirt. To do this, wipe it with a dry cloth. If it does not help, wipe it slightly damp, and then dry. Moisten the cloth with water, not a cleaning liquid, because aggressive liquid can damage the strokes on the encoder and you will have to change it to a new one.

Problems with reading the encoder disc.
Encoder disc. Wheels on the side of the printer that are geared to the paper feed motor. It also has marks by which the printer determines the position of the sheet when printing. If ink or dirt gets on it, it will fail to read and cause cross-stripes on the print. The stripes will appear at an equal distance between each other, corresponding to a full revolution of the disk.
As with tape, the problem is solved by carefully cleaning the encoder disc from contaminants.

Laser printer prints in stripes

Possible causes of the problem:

  • Toner low.
  • The tightness of the cartridge is broken.
  • Waste Toner Box.
  • Blade not installed correctly.
  • Defective magnetic roller or drum unit.

How to fix the problem:

For laser printers, the cause of the problem can be determined by the nature of the streaks in the print.

Printed streaks occur in random, different places.
The cartridge is likely to be damaged. Remove it from the printer and check if toner is spilling. Make sure all rubber seals are in place. A leaking cartridge should be replaced with a new one.

Random stripes when printing

The stripes are made up of small dots.
There may be several reasons: the cartridge is incorrectly refilled, the waste toner reservoir is clogged, or for some reason the dispensing blade is incorrectly installed.
Will help: refilling the cartridge with toner, cleaning the reservoir and correctly installing the blade, respectively.

Dotted stripes on a photocopy of a passport

Stripes are NOT permanently printed on the same part of the sheet
Either the toner cartridge is low on toner, or a foreign object is on the cartridge shaft. Check the toner level and refill the cartridge if necessary. If this is not the case, check the shaft and remove any foreign objects.

White streaks when printing

There is a wavy dark stripe around the edge of the print.
The point is most likely in the drum unit. It has worn out, or completely out of order. In this case, you need to replace the imaging drum in the cartridge, or the entire cartridge.

“waves” on the sides of the page for problems with the drum

Dark stripes are equidistant from each other
This is probably just an overflow of the toner reservoir. You should check it and the correctness of refilling the cartridge as a whole.
If it does not help, then most likely the contact between the magnetic shaft and the drum is broken. This happens due to wear of the parts in the cartridge. Replace worn parts with new ones, or install a new cartridge.

Horizontal black stripes from a faulty charging shaft

What to do if the laser printer starts printing with stripes

Often, users of printing equipment have to solve the following problem: why does a laser printer print with stripes? Of course, during long-term operation, the quality of office equipment, in particular, the all-in-one printer, gradually decreases, as a result of which stripes begin to appear when printing. But a similar problem plagues even brand new laser printers. So what’s the reason?

The main reasons and how to eliminate them

So, if, when printing on a laser printer, a line appears on the printout along the edge, then one of the reasons for this problem is that the device is running out of toner. In general, a sign of such a problem is most often the appearance of a strip of white color along the entire length of the sheet of paper. With each subsequent printout, the width of this strip gradually increases. The solution to the problem is to refill the cartridge or buy a new consumable.

But what if the streaks appear when printing on a laser printer even with a full cartridge? In such a situation, an edge band may appear due to laser problems. The optics may have gotten dust, toner particles, or even insects. To avoid a defect, it is necessary to constantly monitor the state of office equipment and clean the scanner mirrors with a smooth, lint-free cloth.

If black stripes appear on the printouts, then this indicates the presence of the following problem: contact on the photosensitive drum periodically disappears. The cause of this problem may be dirt that has adhered to the contacts. Therefore, the solution to the problem is to bulkhead and clean consumables.

In addition, a black band around the edge may appear due to damage to the drum unit, which is a key part of the laser printer cartridge. Its light-sensitive coating is gradually erased during the operation of office equipment, which leads to a deterioration in print quality. But usually a sign of a drum defect is grayish-black stripes, which have a wavy shape and are displaced towards the edge of the sheet. The solution to the problem is to completely replace this part. In addition, the manifestation of a defect may be due to the fact that the conductive grease on the contacts of the photo roll has dried out. This usually happens when the device is NOT used for a long time. To solve the problem, you need to disassemble the cartridge and replace the grease on the contacts.

If the printer strips with printers and none of the above has helped, then perhaps a prerequisite is damage to the magnetic roller. This is usually indicated by the appearance of horizontal streaks in a dark shade or excessive background. Elimination of the defect is a complete replacement of this part.

An edge band may also indicate cartridge leaks or squeegee wear. Spilled toner is the cause of print quality deterioration. If you notice traces of toner in the printer or consumable housing, check the condition of the seals and mylar film in the waste bin. If you find areas of accumulation, try to eliminate them or replace the cartridge.

If the printed sheet upset you with the print quality, then check the waste reservoir. it may be full. The presence of a similar problem is indicated by the appearance of vertically located stripes, which consist of small chaotic dots and dashes. In this case, the stripes are shifted to the right or left edge of the sheet. You can fix the problem by thoroughly cleaning the cartridge waste bin.

In addition, a white edge band that appears along the length of the sheet when printed may indicate wear or contamination of the dosage blade. The reason for the violation in its work is the use of poor quality paper. As a result, the paper fibers begin to adhere to the blade. In turn, the magnetic roller in the places where THESE fluffs accumulate does NOT pick up toner and the printed letter acquires a defect in the form of a white stripe. To get the seal back to normal, you will need to make sure that there is NO dirt under the dispensing blade and that it is properly installed. If necessary, we will clean this part using alcohol or acetone. If the dosage blade is in a badly worn condition, then we will replace it.

In addition, the failure of a part such as a charge roller or otherwise corotron can also deteriorate the print quality. You can fix the problem if this part is severely damaged by replacing it with a new one.

So, if the laser printer began to print with stripes, you found out what to do. As you can see, most likely the cause of the problem lies in a malfunction of the cartridge or its contacts in the device. For more information on the concepts of what to do is out of order, the article about the main defects in printing laser cartridges will help.

What to do if the printer slashes when printing. Printer Prints Stripes. Troubleshooting

An inkjet printer prints in stripes. Possible causes of the problem:

  • Low on ink.
  • Printhead nozzles (PG) clogged with dried ink.
  • Air is trapped in the print head.
  • Malfunction of the mechanics or electronics of the printer itself.

Ink level problems. What can be done:

Sins of ink level follow when the printer starts to print streaks on photos or documents unexpectedly. It’s not about ink if: you recently changed or refilled the cartridge, there was a malfunction (for example, the paper was jammed and you pulled it out of the printer) or something happened to the printer itself (it was turned over, dropped, or was in the cold for some time ).

Check ink levels programmatically and replace cartridge.
Select Maintenance or Service from the printer control menu. Run an ink level check. If there is little or no more. replace cartridges.

Visually check the ink level in the ink tank (if you are using one) and refill.
In refillable cartridges, the actual ink level may NOT coincide with the meter reading, so remove the cartridges and visually check the ink level. If there are very few of them left, the cartridges should be refilled.

Check the efficiency of the CISS (for those who have it installed)
Make sure there is enough ink in the donor bottle. Check if something is interfering with the flow of ink through the plumes, as well as at what height the donor containers are (sometimes it makes sense to raise them). If air gets into the plumes, it should be removed from there. For details, see the instructions for removing air from CISS loops for Epson. Or instructions for Select HP and Canon models. If the plume is forgotten with dried ink, it should be cleaned or replaced.

Change old ink (for owners of refueling complexes and CISS)
It is unlikely that the streaks when printing “suddenly” appear due to old ink, but the expiration date should still be checked.

Printhead problems. What can be done:

You should pay attention to this item first of all, if the stripes during printing appeared after a long idle time of the printer (they did NOT print for more than a week, and it was NOT preserved) The occurrence of problems with GHG may also be preceded by manipulation of the printer, transfer from place to place, change or refilling of cartridges, attempts to “get inside” without proper preparation.

Runs “Nozzle / Nozzle Check”
In the printer control menu, select the item “Nozzle check” or “Nozzle check” (depending on the printer model). A printout of a test page will help determine the cause of the problem and possibly even fix it using software.

Runs “head cleaning”
In the printer control menu, select the “Head cleaning” or “Nozzle cleaning” item. You can run it several times, but always with pauses of 5-15 minutes. If several of these procedures did not help, proceed with cleaning with service fluid.

Flush the printhead (PG is located in the cartridge)
If you have a two-cartridge printer, then the PG is on the cartridge. Try to rinse it according to the instructions (point 1), if it did NOT work, then the cartridge will have to be replaced.

Cleans the print head with service liquid (the PG is located in the printer)
The method is relevant in case of severe clogging or air ingress into the print head. Use a syringe, cleaning fluid, and lint-free wipes to thoroughly clean the nozzles.
Step-by-step instructions can be found in the detailed instructions for cleaning the steam generator.

Other printer malfunctions.

In the vast majority of cases, the problem of streaking during printing is associated with the ink and print head, but sometimes with malfunctions in the printer mechanics. In this case, we recommend that you contact the service specialists, since an attempt to “get inside” without special knowledge can lead to permanent damage to the device.

Problem with reading the encoder tape.
Encoder (raster) tape. A strip stretched inside the printer with strokes, with which the device determines the position of the print carriages in space. By chance, ink or dirt can get on the tape, because of which the printer will stop “seeing” some of the strokes and will begin to “slip” part of the sheet when printing. As a result, one or more longitudinal (vertical) stripes will appear on the page.
The problem, in this case, is solved by cleaning the tape from dirt. To do this, wipe it with a dry cloth. If it does not help, wipe it slightly damp, and then dry. Moisten the cloth with water, not a cleaning liquid, because aggressive liquid can damage the strokes on the encoder and you will have to change it to a new one.

Problems with reading the encoder disc.
Encoder disc. Wheels on the side of the printer that are geared to the paper feed motor. It also has marks by which the printer determines the position of the sheet when printing. If ink or dirt gets on it, it will fail to read and cause cross-stripes on the print. The stripes will appear at an equal distance between each other, corresponding to a full revolution of the disk.
As with tape, the problem is solved by carefully cleaning the encoder disc from contaminants.

The laser printer prints in stripes. Possible causes of the problem:

  • Toner low.
  • The tightness of the cartridge is broken.
  • Waste Toner Box.
  • Blade not installed correctly.
  • Defective magnetic roller or drum unit.

How to fix the problem:

For laser printers, the cause of the problem can be determined by the nature of the streaks in the print.

Printed streaks occur in random, different places.
The cartridge is likely to be damaged. Remove it from the printer and check if toner is spilling. Make sure all rubber seals are in place. A leaking cartridge should be replaced with a new one.

Random stripes when printing

The stripes are made up of small dots.
There may be several reasons: the cartridge is incorrectly refilled, the waste toner reservoir is clogged, or for some reason the dispensing blade is incorrectly installed.
Will help: refilling the cartridge with toner, cleaning the reservoir and correctly installing the blade, respectively.

Dotted stripes on a photocopy of a passport

Stripes are NOT permanently printed on the same part of the sheet
Either the toner cartridge is low on toner, or a foreign object is on the cartridge shaft. Check the toner level and refill the cartridge if necessary. If this is not the case, check the shaft and remove any foreign objects.

White streaks when printing

There is a wavy dark stripe around the edge of the print.
The point is most likely in the drum unit. It has worn out, or completely out of order. In this case, you need to replace the imaging drum in the cartridge, or the entire cartridge.

“waves” on the sides of the page for problems with the drum

Dark stripes are equidistant from each other
This is probably just an overflow of the toner reservoir. You should check it and the correctness of refilling the cartridge as a whole.
If it does not help, then most likely the contact between the magnetic shaft and the drum is broken. This happens due to wear of the parts in the cartridge. Replace worn parts with new ones, or install a new cartridge.

Desktop printers contain sophisticated combinations of permanent moving parts and consumables designed for periodic replacement. When your office printer produces a printout that shows streaks across or along the pages, you’re wasting paper and supplies until you diagnose the problem. Where you direct your troubleshooting will depend on the types of output defects you see and the type of printer you are using.

Inkjet Print Head

Inkjet printers are working, heat tiny nozzles or apply an electric current to them to reshape them, forcing ink onto the page. When you see voids in your prints or horizontal lines across it, there might be a clogged nozzle in your printhead. Inkjet printers do not tolerate downtime, and you may need to clean the head several times to remove dried ink. If defects in your output interfere with the appearance of vertical lines on your page content, the Printhead may need to be corrected. Both cleaning and re-tuning will consume some of the installed ink, especially if your equipment requires deep cleaning or multiple adjustment cycles.

Laser toner or drum cartridge

Laser printers create a full page of content in one go by transferring toner to paper from a rotating drum and using a heating element to melt the toner. The drum is either part of the toner cartridge or is installed as a separate consumable. In any case, scratches on the light-sensitive surface may result in streaks or lines at the exit. Most cartridges have a spring-loaded shutter that opens when you insert the supplies into the printer; if you remove the cartridge and carefully open the shutter, being careful NOT to touch the drum or anything else inside the cartridge, you may see scratches on the surface. To rule out consumables as source of problems, replace the cartridge and reprint the document page.

Laser fuser

Toner consists of a mixture of shredded plastic and dyes. To adhere it to the paper, laser printers use a heating element called a fuser to melt the toner as the paper moves through the fuser rollers. If toner settles on the fuser or the rollers are damaged, you may see unexpected vertical lines in the prints. To diagnose lines that form a repeating pattern, you can find the line of repeating defects published by the printer manufacturer for your model of equipment. Throughout this document, the origin of marks on a page is identified by their location alongside the rollers and other components of the print mechanism. Certain manufacturers Provide these service manuals to service technicians only.

Dirty printer

Loose toner trapped inside the laser printer can get caught on the rollers or other moving parts and appear as streaks, streaks or lines on the print. Many roller marks form a distinctive tire print pattern on each sheet as the paper travels through the printer. Removing THESE defects requires a two-step approach. Tracking source of accidental toner can lead to a leaky cartridge, which gradually fouls your device, or a one-time accident caused by an attempt to reprint a page from another device that melts at a lower temperature than your printer will use.. depending on your experience and your printer design.

I hope you can help me.
My epsom printer, which is a little more
1 h, prints in stripes, and I don’t know what to do about it.
I uninstalled and reinstalled the printer software
I disconnected and reconnected her to electricity
I cleared heads several times
and changed ink cartridges
, so now i’m lost, any help would be much appreciated
thanks in advance.

Marie: We need to know which direction the stripes are going: vertically, top to bottom on the paper [11 “direction] or horizontally, side to side [8 1/2” direction]. We also need to know the real model of your printer. Danny Conway

Marie: When I see horizontal or colored lines [side by side on the page] that are printed on the photographs, it usually happens to either a faulty “printhead assembly” or a faulty “main board assembly”, but there is no way to know, of course Generally speaking, cleaning usually does not help if it is an equipment / parts problem that is actually causing these types of lines. HOWEVER: There is a slight chance that accumulation of dried ink, dust, dirt, lint and hair, which may have accumulated on the bottom and back of the printhead assembly, can sometimes cause “printhead nozzles” to appear.

What are the causes of lines on the page of a laser printer | Small business

Laser printers. From small desktops to workgroup computers. Give your business years of trouble-free operation. When your trusted hardware starts to create pages with vertical or horizontal lines that are NOT part of the content you are printing, start troubleshooting with simple possibilities before you assume the worst. You can narrow down the source of THESE defects by matching the symptoms you see with the suspect that may be causing them.

Roller guides

If toner seeps out of the cartridge and into the mechanical parts of the printer, it can get dirty on the rollers that move the paper through the device. The “tire marks” pattern created by this contamination appears at the edges or in the middle of the sheet and matches the position of the rollers in the paper path. If you are NOT a printer specialist, leave this cleaning job to a professional, especially if your equipment is still under warranty; however, replace the toner cartridge (or cartridges in the Color Printer) before contacting a service center to rule out faulty consumables as a cause.

Vertical stripes or lines

Depending on whether you see vertical defects in black or white. Printed marks or voids in the print. You may be dealing with a nearly empty toner cartridge, a scratched or malfunctioning Distributed toner cartridge. Replacing the cartridge with another should help you rule out the culprit. Vertical white lines can also signal an obstacle that prevents the laser from displaying pages correctly. This issue may require cleaning or replacing the laser assembly.

Horizontal lines

Horizontal imperfections and marks that appear at regular intervals can be caused by dirty rollers. Manufacturers provide model-specific repetitive defect lines that can be used to correlate the position of defects on a page with the position and size of rollers, cartridge components, fuser parts, and other potential causes of non-random marking. Dropouts and non-repetitive marks can be the result of the same issues that cause vertical defects including laser contamination and toner cartridge faults.

Recommendation

Toner cartridges. These are the main replaceable parts in laser printers. Exposure to light will damage drums and degrade print quality. Contaminants trapped behind the paper can also leave scratches that prevent proper display. Since print defects can appear at any time, having spare ink cartridges on hand will allow you to get back to work immediately if your supplies are defective. Many of the second potential causes of lines and streaks in your exit. Especially lasers and fusers. Can pose a safety risk to well-intentioned but unskilled people. If you are NOT sure what you are doing under the lid, put the tools aside and leave the work to a specialist.

What does it mean when the printer stops printing words? | Small Business

When your office printer experiences problems that affect some but not all of its products, the mysterious combination of what prints and what doesn’t make it imperative to troubleshoot what looks like a tricky puzzle. The fact that it stops typing text gives you the biggest clue to its possible solution, because type-related symptoms often boil down to reasons that indicate their origin. Along with restarting the system and trying to use a new data cable to eliminate the shared data connection, you can look for the source of this misbehavior in software and, in some cases, in hardware.

Printer driver

To enable the operating system and the printer to communicate, you install the printer software that provides specific support for your printer and its features. When you fix or update your operating system, the drivers you used to install a Windows or Mac update may become incompatible with the updated system software. The results of a mismatch between the computer and the printer may manifest as incorrect output, blank pages, or printing failures. These same symptoms can occur if your driver software is damaged during a lightning storm, power surge or power outage, or if malware has infiltrated your computer. Visit your hardware manufacturer’s website to download a new driver.

Typeface

Font software performs better than just about any hidden resource that supports your operating system. Word processing, desktop publishing, and even your computer’s onscreen user interface (OSI) rely on font files to provide output and display information. When a typeface becomes damaged from use or from installing a corrupted font file, your Typographic Output suffers. Text disappears on paper, on screen, or both, and elements that appear may look like they were. Scattered across the page by a strong wind. Removing and reinstalling a headset with symptoms of malfunction should fix the problem. If you have just purchased and downloaded a font, you may need to purchase a new copy of its files.

Document

Documents you create can fall prey to internal damage caused by saving a file during an electrical wobble, writing a document to a faulty disk, and a long list of problems caused by recurring conditions that never recur. A file with a long history can cause problems, especially if you create new ones. Project instances by opening and customizing a copy of a previous version instead of using your software’s template document format. The file may display normally in your application and suddenly print incorrectly. Except for recreating the project by rebuilding it from scratch, you can copy its content and paste it into a new document using the clipboard, drag and drop, or a special file transfer procedure provided by your application.

Printhead

If you use a thermal or shock device such as a dot matrix or specialty label printer, the Printhead that powers its output may fail and nothing will appear on the paper. Dot matrix printheads DO NOT crash suddenly or catastrophically. Instead, the inferences that produce inference stop working one by one for a long period of time. If you have NOT used the printer for a long time, you may have forgotten its shortcomings, but perhaps you can find parts and have it repaired. On the contrary, thermal printers can and do stop working due to head failure, which occurs without warning. Most of THESE failures require replacement of the device, not the head.
