White stripes when printing, what should I do? Symptoms

When printing, a vertical white stripe or a large number of them may be accompanied by gray on the sheet, dots, black stripes. It is important to remember after which they appeared in order to give the correct diagnosis to our “patient”.


1) Usually the cause of light streaks is a corny toner. How to understand if this is the case? It’s SIMple. if the cartridge has been refueled for a long time, then this is probably the case. Just shake the cartridge gently over important documents 🙂 (but, nevertheless, better over the urn). Wipe the cartridge from dust and all kinds of dirt with a dry napkin, or better with a napkin for office equipment (It does not leave lint), and insert the cartridge back into the printer. If the stripes have disappeared, then you will be able to print a dozen more pages, but it’s time to call the refueller. In this case, it really is a matter of running out of toner (ink).

2) A second common prerequisite is that toner gets on the laser glass. Typical for Panasonis and Brother printers. If the laser in the printer is under the cartridge, then the glass is very likely to be clogged. How to check? Wipe down the cartridge seat, check operation after this change. If not, try inserting another cartridge (if available). And read the rest of this article.

3) Dark vertical stripes most often in the middle of the sheet are typical for Canon and HP compact prints. The fact is that the cartridges are designed for THESE printers in such a way that they have a small bin for waste toner.

Solution: If your printer has let you down and starts printing with faint stripes, or even white, one of the reasons is that the waste toner box is full, although the new toner box is NOT empty yet. Your refueller, apparently, did not regret the paint. It’s not a problem, it’s just time to refuel.

3.1) A dark line on the side, or on both sides, with a repeating pattern approximately every 7 cm. If you have not changed the drum unit for a long time (more than 4 cartridge refills), this is a clear sign of drum wear. In this case, replacing the drum unit in the cartridge will help.

4) Black letter with light stripes. This problem is much less common, and if it does, then preferably in Panasonic printers. Why is this happening? There are contacts on the cartridge, usually they are on the sides, the charge is transferred to them, which goes to the drum and to the secondary charge shaft (if you want to learn more about the printer device, the article laser printer device will help you).

Solution: Wipe the case with a dry cloth for office equipment, pay special attention to the side parts. there are contacts. Check if the contacts are dirty, wipe them with alcohol. Reinstall the cartridge until it snaps into place.

5) White horizontal stripes when printing can also be caused by your favorite pets. Their wool can really clog the cartridge and it will print, at best, light stripes, at worst. some of the parts in the cartridge will have to be replaced.

A few tips from the author: do not keep the printer on the floor or in a space closed on all sides: in the first case, it will absorb dust, and in the second, it will overheat. Wipe it from time to time with a slightly damp cloth and do not get into it damp or b. B. Paper. This causes wear on the drum unit.

Vertical stripes when printing on a laser printer

Modern office equipment is sometimes quite finicky in operation and laser printers are no exception. One of the most common printing defects indicating a device malfunction is vertical streaking on the paper. This article will show you what to do if your printouts start to have streaks.

Why do streaks appear when printing on a laser printer

There are a number of reasons why a printing device can leave streaks on documents. Among them:

How to remove vertical stripes when printing

Laser problems or low ink levels are indicated by white lines appearing on the printed pages. In the case of a lack of ink, the solution to the problem is SIMple. you need to refill the cartridge. Worse if the laser is not working properly. For proper and long-term operation, experts strongly recommend Monitor the condition of the device, regularly wipe the scanner mirror with a clean and smooth cloth.

Drum damage may be indicated by gray-black, wavy stripes, usually located along the edges of the sheet. OPC drum damage is the result of trivial wear and tear during long-term use.

Replacing the part with a new one is considered an acceptable solution to this problem.

The same applies to the magnetic shaft: it is impossible to repair this part and any service center, if defects are found, will immediately offer to replace it. The first sign of magnetic roller wear is a gray background of the document and horizontal dark stripes on it.

If a single vertical white stripe appears on the printed document all over the page, a malfunction of the metering blade may be the cause of the breakage. The blade itself is part of the cartridge. It is responsible for the amount of toner that gets on the magnetic roller.

Blade malfunctions in most cases are associated with the introduction of poor quality paper. The fluffs of such paper quickly stick to the metering blade, and the magnetic roller in the place of their accumulation can no longer pick up paint evenly. In order to return the parts to work, it is necessary to carefully wipe its surface with alcohol.

If the document is printed with black stripes across, then a prerequisite for the volume may be poor contact between the magnetic roller and the drum unit. Contact deteriorates due to dirt adhering to the parts. Cleaning the cartridge will help solve the problem in this case.

Streaks of streaks and specks running vertically along the entire page can indicate spills and can be easily removed by cleaning the waste cartridge.

Does the laser printer print in stripes and third-party artifacts? Solving the most popular problems!

Sometimes it happens that laser printers begin to produce stripes, blots, dots or other third-party artifacts on the leaves during printing.

The causes of such problems can be caused by both low-quality toner and problems with the cartridge:

  • Incorrect assembly of consumables after refueling;
  • OPC drum worn out;
  • Depressurization of the bunker with paint, etc.

Also, many inexperienced users who prefer to do everything with their own hands often refuel the cartridge “to the bitter end.” And this, in turn, leads to the failure of its SEPARATE units and parts, which negatively affects not only the quality of printing, but also the performance of office equipment as a whole.

Therefore, today we will tell you why you get streaks while printing on a laser printer, and also share recommendations on how to get rid of this.

Horizontal black bars? Cleaning the waste toner box and checking the magnetic roller contacts!

The solution to the problem of horizontal black streaks is that you need to clean out the waste paint hopper and then check the correct positioning of the metering blade and squeegee.

Be sure to also correctly install the contacts between the drum unit and the magnetic roller.

Horizontal black stripes

TOP Vertical stripes around the edges? Drum (photo drum) wear!

Probably the most common problem caused by running out of drum life. Often found in cartridges that have been refilled with toner several times.

If this is your first time refilling the cartridge, then most likely it will be enough to wipe the drum unit with a clean cloth. Detergents, in this case, are prohibited to use, so you will only harm!

Vertical stripes around the edges

TOP White stripes or gaps during printing? Refill the cartridge!

As soon as the printer began to leave white streaks or skip certain elements on the prints, then it’s time to think about refilling used cartridges or buying new cartridges.

Sometimes it happens that third-party particles get onto the photo, which become the source of the above problems.

White stripes or gaps

TOP Dots with stripes in a chaotic order? Check the dispensing blade!

Small dots all over the sheet accompanied by vertical streaks can indicate three potential printing problems caused by:

  • Incorrectly installed metering blade (needs to be corrected)
  • Waste toner box full (clean it)
  • Low-quality toner, or the cartridge is filled with new dye powder, the remains of the old one have not been disposed of (you need to replace the toner).

Dots with stripes in a chaotic manner

TOP Chaotic stripes and artifacts? Eliminate cartridge depressurization!

If the tightness of the cartridge is broken, eliminate the problem by checking the integrity of the sealing gum, without which, most likely, toner spills.

Problems with the metering blade

One of the elements of the cartridge is the metering blade. It controls the amount of toner delivered to the magnetic roller during printing. Poor quality paper used for the printer can be one of the causes of this breakdown. Fine fluff from the paper will accumulate on the blade, and therefore the roller will NOT be able to pick up enough toner where they accumulate. As a result, the printed document will have a white stripe along the entire length of the page.

To restore print quality, you need to make sure the metering blade is properly seated. If blockages are visible, the blade must be cleaned, and in case of complete wear, replace it.

Stripes when printing on a laser printer: causes, solutions

During the use of laser printers for the output of various documents to their owners, problems often arise associated with the deterioration of print quality. In particular, the resulting document may contain horizontal or vertical stripes of different lengths.

There may be several reasons for this, namely: running out of toner in the cartridge, problems with the laser, damaged imaging drum or magnetic roller, Broken contact between them, leakage of the cartridge, Overfilled waste, damage or failure of the charge roller.

Also, the appearance of horizontal and vertical stripes when printing on a laser printer is possible due to a drop or malfunction of the cartridge, or improper refilling. Poor toner quality should NOT be ruled out as a cause.

Photoreceptor and magnetic roller contact problems

When printed with a laser printer, horizontal black stripes indicate that there is no or no contact between the drum unit and the magnetic roller. In most cases, contamination from the contacts contributes to this. To solve this problem, you need to clean the cartridge.

Waste Toner Box Overflow

If toner spills when you remove the cartridge, check the fill level with waste. An overfilled hopper can also be indicated by vertical black bars when various files are printed on the laser printer. They can consist of scattered small stripes and dots and are located along the entire length of the document. Also, these stripes will be located to the right or left of the center of the sheet. This defect can be eliminated by cleaning waste from the hopper.

Failure of the magnetic shaft

In the design of a laser printer, a magnetic roller is used to transfer ink from the hopper to the drum. The absence or presence of defects, such as streaks, when printing on a laser printer directly depends on how evenly the toner is supplied to the photoreceptor. A noticeably darkened gray background or small dark stripes indicate, first of all, a deterioration in the properties of the magnetic shaft. The problem can be eliminated by replacing the failed shaft.

Malfunction of the charging roller

Charge roller problems can be diagnosed if all or part of the document is duplicated during printing. The charge roller, aka corotron, is a metal rod with a rubber sheath. A charge passes through it to the surface of the drum when printing is started and the final static voltage is removed thereafter. Incorrect operation of the charging shaft is caused by such malfunctions as:

  • Contamination on the rubber surface of the shaft or its wear;
  • Tears or punctures in the rubber coating;
  • Electrical breakdown or change of electrostatic parameters.
Stripes When Printing On A Laser Printer

If there is visible damage on the rubber coating of the shaft, then to eliminate duplications and stripes when printing on a laser printer, it is worth checking if there is an electrical contact on one shaft, and also clean the rubber jacket. If these manipulations did not give a positive result or there is mechanical damage in the roller device, it is necessary to replace it.

White stripes on the document

If you see white streaks when printing with a laser printer, the cartridge is most likely out of toner or the problem is with the laser. The finished ink says a wide white stripe along the entire length of the page, which will increase with each subsequent attempt to output the letter to the paper. It is worth noting that if the toner in the cartridge has run out, do not take it out and shake it, since these actions will NOT affect the print quality in any way, and the drum unit may be seriously damaged or completely out of order. The solution to the problem is to refill the cartridge.

If toner is present and streaks remain, the problem is most likely in the laser. It doesn’t have to be serious. It is possible that dust, small insects or paint particles have gotten on the optics. To prevent this, you need to keep the printer clean and, if necessary, wipe the laser mirror with a lint-free cloth.

Leakage violation

If, when printing on a laser printer, stripes appear in different places throughout the page, most likely the problem is in the cartridge itself. To find out the cause of the malfunction, you must pull the part out of the printer and inspect it carefully. If toner spills from it, you need to make sure there are seals and there are no traces of mechanical stress, such as cracks or chips. If an uncorrectable defect is found, only replacement of the cartridge will help.

Image drum worn

The drum unit, in other words, the photoreceptor, is the main component of the cartridge. It consists of a coated aluminum shaft that is sensitive to optical radiation. Over time, the coating wears out, which is why streaks appear when printing on a laser printer.

The first sign of damage to the drum unit will be gray-black wavy lines on one edge of the printed document. The problem is solved by replacing the drum unit. Also, streaks may appear due to dried lubricant on the photoreceptors. Such a malfunction occurs quite often, especially if the device has NOT been used for a long time. It can be solved much easier: just run the printer cleaning program from its settings menu on the computer.

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.

“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 the 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, in order to determine how much the cartridges are used up in HP equipment, you need to start the program designed to manage the machine and select the “Estimated ink levels” tab. 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 loop 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.

Problems with encoder tape and disc

Also, a prerequisite for the fact that a white line appears during printing, which repeats 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.

Damage to the drum unit

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.

Leaky cartridge

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.

Why do streaks appear on the printer when printing?

Any printer, be it laser or inkjet, in the process of operation comes to a stage of its work when the print quality deteriorates. Printed pages become dull, horizontal or vertical streaks appear on the sheet, 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.

Toner Empty

You can tell that the toner cartridge has run out of toner if white stripes of different widths appear on the sheet.

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

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, it is required to regularly turn on the device so that it can “blow” the nozzles with ink.

In modern printers and MFPs, 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 if 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 did not help, then you will have to resort to manual flushing of the printheads, as shown in this.

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 that of a new printer. Therefore, if there is a suspicion that the nozzles are dry, it is better to contact the service center.

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.

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:

  • Low ink level.
  • 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.

What causes streaks when printing in an inkjet printer?

There are several common 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 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 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 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 there are white and unprinted stripes 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 its replacement 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 times more. 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 Canon Pixma MG2440 inkjet MFPs. 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 MFP, then the malfunction of the head is SIMply due to natural 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? So, you should contact the service center for help. Or even seriously consider buying a new device.

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? This does not 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.

What to do if a 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, in the course of long-term operation, the quality of office equipment, in particular, the MFP 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 the 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 the 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. In this case, spilled toner is the cause of the 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 arranged 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. If this part is severely damaged, you can fix the problem 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 an inkjet printer prints with stripes

Any office equipment, in particular, an MFP and a printer, sooner or later begins to “junk”. One of the common problems that over time begins to bother many users is the following: an inkjet printer prints with stripes. Most often, the prerequisite for such a printing defect is the contamination of the device mechanism with dye particles and the trivial wear and tear of its components.

Possible causes and remedies

If your inkjet printer is streaking, the first thing you should do is check the ink levels. For this purpose, you need to run the utility that allows you to control the printing device and go to the “Service” / “Hardware” tab in the window that opens. Next, run a check, the results of which will be presented to you in the form of an image. If you have a color printer, the screen will display the ink level of each color that comes with it. But if you have CISS, i.e. Continuous ink supply system, in this case it is possible to determine how much ink remains in the bin of consumables only “by eye”, ie. Visually. It is quite SIMple to do this, because CISS bins are transparent.

If everything is ok with the ink, but the inkjet printer still prints in stripes, then you should clean the printheads. This part in some inkjet printers is located in the device itself, in others it is included in the cartridge. If you have a printer of the second type, then you can solve the problem of stripes that appear during printing by SIMply changing consumables. But if such a replacement is impractical, for example, the reservoir of the cartridge is still captivated by paints or the purchase of a new element will hit your. then you can start cleaning the head. This problem can be solved programmatically using a special utility. If this does not help and the printer leaves all sorts of defects on the printouts, then you will have to do manual head cleaning, for which you should use a special flushing liquid. For more information on how to flush the print head read this article.

In the event that you have installed CISS, then Make sure that the holes for air in the cans are not blocked. But if they are equipped with a filter, then check the degree of contamination. If necessary, remove them or replace them better.

If the next question is still relevant: the inkjet printer prints with stripes what to do. then you should make sure that the print head is in good condition. THOSE. If neither software nor manual methods helped to solve the problem of white stripes, then perhaps the cause of the defect lies in the head itself or related details. Most often, the breakdown of this element occurs due to careless handling when removing it or due to frequent use of the device. To eliminate the breakdown, you will have to completely replace the failed part.

To answer the question of why streaks appear when printing with an inkjet printer, you may need to perform head alignment. The fact is that when moving the printer from one place to another, the carriage of the device could be slightly mixed. You can fix the problem using special software, in which you need to select the “Align printheads” option and follow all the recommendations that will appear along the way.

The appearance of white stripes, which are located at the same distance from each other, may be due to contamination of an element called an encoder disk. This part is located on the shaft, which is responsible for feeding the paper and is a circle with markings made of transparent material. In the event that the lines are covered with dried paint or a layer of dust, then the Corresponding sensor of the device will not notice them. This will lead to incorrect positioning of the paper. The elimination of the problem involves cleaning the surface of the encoder disk with a tissue. In this case, it must first be moistened with a liquid specially designed for cleaning such parts. If you couldn’t find it, then a remedy like “Mister Muscle”, which contains ammonia, is quite suitable.

Also, a prerequisite for a print defect can be the encoder tape, which is responsible for positioning the carriage. If its markings are covered with dust or ink, then part of the text is shifted to the left or right side during printing. A SIMilar defect will be repeated throughout the sheet at regular intervals. This strip is placed with markings in the form of dashes along the main shaft for feeding paper. Please note that you need to wipe it painstakingly, otherwise this tape will easily jump off its mount and in order to reinstall it in place you may need the help of a wizard.

In addition, the banal ingress of foreign objects inside the mechanism or the adhesion of waste ink from the diaper to the printer carriage can become a prerequisite for the appearance of stripes. In this situation, clean the carriage yourself. If, after all the manipulations, the printer prints with spaces, taking its device to the service center, most likely it will have serious repairs.

Stripes when printing on a laser printer

What is the reason for the stripes

  • Low toner.
  • Depressurization of the cartridge.
  • Filling the waste powder colorant container.
  • Incorrect squeegee installation.
  • Breakage of magnetic or photocell.

What to do if the printer prints with stripes

How to fix

Uniform white streaks appear on the paper when toner is low.

It is better to buy a certified powder, and if you refuel yourself, all work is carried out in a well-ventilated area due to the high toxicity of toner.

To identify leaks in a cartridge, remove it from the printer

  • Next, inspect for cracks, chips, loose areas;
  • Check the places where the bolts are screwed;
  • Shake the cartridge gently to check if powder is spilling
  • Slide the shutter near the photogallery, see if there is toner on it.

Often times, the printer will strip due to the lack of periodic cleaning of the waste toner box. If cleaning is NOT done after each refueling or at least once in two refills, continuous wide stripes will be printed on the paper.

When the photo roll is worn, the stripes will be printed on the side of the sheet: case, on the left, depending on the side of wear, or on both at the same time.

SIMilarly, you need to act if the magnetic and photo roller do not fit well together or the dosage blade (squeegee) is faulty. The blade changes with the magnetic shaft.

If the blade is just dirty with toner or a foreign object has fallen under it, cleaning it can help.

  • The cartridge is ejected.
  • On its body, 8-9 screws are unscrewed, located on both sides.
  • The top cover is removed, under which the magnetic shaft with the blade.
  • Excess items are removed from under the squeegee, and the surface of the blade is gently cleaned with detergents. It is better to clean the sharp part with a wooden stick.

What to do to correct the print

Sudden streaks when printing pictures or text documents may appear due to low ink levels.

    Software check of the amount of dye. Go to the properties of the printing apparatus, click on “Service” or “Service”.

Starts a test with paper inserted in the tray. If there is little ink, a new cartridge is bought.

If the printer has been left idle for a long time, or if it has been moved frequently from place to place, streaking may be due to problems with the print head. For the same reason, poor printing becomes after refilling the cartridge or replacing it by users with no experience.

  • Checking the nozzles / nozzles. In the properties of the printer, select “Check nozzles” or “Check nozzles”.
  • Programmed head cleaning. For Epson: in the properties on the “General” tab, press “Settings”, click on “Cleaning printheads” or “Cleaning nozzles”. The start of the procedure is repeated if necessary after 5-15 minutes. When stripes appear on a Canon printer, go to the “Printer Properties” and on the “Maintenance” tab, one by one start the “Cleaning” and “Deep Cleaning” options. Recommended for prophylaxis to reduce dye consumption. In models without a pump (for example, Canon Pixma MG2440) software cleaning does not work, it is done only manually.
  • Manual cleaning of the print head built into the cartridge (Canon, HP). The inkwell is placed on a rag dipped in warm cleaning liquid, nozzles down. After 5-10 minutes. Wipe the surface dry. If after that the stripes have NOT disappeared, the cartridge must be replaced.
  • Manual head cleaning in a printer (Epson). If the nozzles are heavily soiled or air enters them, a syringe, cleaning agent and lint-free wipes are taken for cleaning.
  • Ink or head problems are the main ones. In rare cases, stripes occur due to failures in the mechanics of the device itself or wear of parts.

    • The encoder tape is NOT read. When dye or dirt gets on it, the part stops “recognizing” some of the strokes, which leads to the printing of one or more vertical stripes. To fix the problem, it is enough to clean the tape with a cloth soaked in water and then wipe it dry. Do not use acetone or other solvents, they destroy the markings on the tape. They act carefully so as not to move the ribbon from the carriage, otherwise a complete disassembly of the printer will be needed.
    • The encoder disc is NOT read. The part has the shape of a wheel with markings applied to it to determine the position of the letter during printing. When the marks become dirty with ink, readings fail and horizontal stripes are printed on the paper. They will be at the same distance from each other, corresponding to a full revolution of the disk.

    Rarely, defects on a printed document appear due to software malfunctions. The software can be damaged by a virus, by the user or during a power outage. The problem is solved by completely reinstalling the driver. Installed from a boot disk or downloaded from the manufacturer’s official website.
