Vertical stripes when printing on a laser printer

Vertical stripe when printing on a laser printer

vertical, stripes, printing, laser, printer

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?

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

As soon as the printer began to leave white streaks or skip individual elements on the print, 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 roll, which become the source of the above problems.

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:

  • an incorrectly installed dispensing blade (needs to be corrected);
  • Overfilled waste toner box (clean it)
  • low-quality toner, or refilling the cartridge with new dye powder, the remains of the old one have not been disposed of (you need to replace the toner).

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 sheets during printing.

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

  • incorrect assembly of the consumable after refueling;
  • drum wear;
  • 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 individual 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 have streaks when printing on a laser printer, and also share recommendations on how to get rid of this.

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, must not be used, so you will only harm!

TOP Horizontal black stripes? 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.

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, a streak along the edge may appear due to problems with the laser. 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 streaks appear on the printout, 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 streak may appear around the edge due to damage to the drum unit, which is a key part of the laser print 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 has not been used for quite some time. To solve the problem, you need to disassemble the cartridge and replace the grease on the contacts.

If the print printer strips and none of the above has helped, then the cause may be damage to the magnetic roller. This is usually indicated by the appearance of horizontal streaks in a dark shade or excessive background. The elimination of the defect is a complete replacement of this part.

A band around the edge can 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 upsets you with the print quality, then check the waste reservoir. it may be full. The presence of such a 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 disturbance 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 very fibers accumulate does not pick up toner and the printed sheet acquires a defect in the form of a white stripe. To bring the seal back to normal it will be necessary to make sure that there is no dirt under the dispensing blade and that it is properly installed. If necessary, clean this part with alcohol or acetone. If the dosage blade is in a badly worn condition, then 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 the malfunction of the cartridge or its contacts in the device. To understand in more detail what to do is out of order, the article about the main defects in printing laser cartridges will help.

Did you know that almost any defect in the printing of a cartridge significantly brings the repair of the printer closer??

As a rule, if the printer prints in stripes or has repeated printing defects, then quite often the cartridge is to blame, and in 95% of cases this cartridge has already been refilled.
So that you at least have an idea of ​​what happened to your brainchild, let’s first figure out what types of defects are on the example of an A4 printer with a cartridge with a capacity of 2000-3000 copies.
The most common defects and the reasons for their appearance will be described below:

a) Vertical stripes of a certain color (including mixed colors, such as green) all over the sheet at the beginning of the cartridge life. One of the cartridges is poorly cleaned (for green, yellow or blue, possibly both); if in the middle of the life. the cartridge is filled with low-quality toner.

In a specific case, this is Samsung CLX-2160, the cartridges of which are just barrels of toner, and the build-ups of toner appeared not in the toner cartridge, but in the image development unit in the machine. On the left of the cartridge, you can clearly see that the yellow toner block has toner build-up on the dispensing blade, which reduces the flow of yellow toner in the areas of the build-up and increases it in the adjacent areas, which immediately reacted to the blue.

b) Vertical stripes in all colors. All cartridges are poorly cleaned;
If in the middle of a cartridge life. Low-quality toner is in the cartridges.

c) The background on a sheet of a certain color is two or more colors. The wrong toner is loaded in a cartridge of this color; the cartridge is poorly cleaned from the remains of the previous toner; cartridge dispensing blade installed with incorrect clearance.

In this case, the metering blade of the blue cartridge is uncleaned (white-blue vertical stripes) and incorrectly installed.

d) The cartridge sprinkles toner at the beginning of the resource.

e) Cartridge sprinkles toner in the middle of its life. Low-quality toner is loaded.

f) Faint printing of any (all) color at the beginning of the resource. poor-quality refilling of cartridges; the wrong toner is loaded; the optics of the device are dusty; the transfer belt is worn out in the machine; photoconductors are worn in cartridges (after several refills).

Here dusting of the Magenta laser in the device, possibly together with the wear of the photo barrel in the cartridge.

In general, Magenta prints fainter than other colors on many HP-Canon flower beds over time due to the dusty optics of the laser responsible for Magenta. The thing is that it is lower than others and more dirt and dust is poured onto it)

g) Faint printing of all colors in the middle of the resource. Low-quality toner is loaded; The photoconductors in the cartridges are worn out (after several refills).

h) Various (repeating and not) defects with new original cartridges. The transfer belt of the device is damaged; one (or all) of the cartridges hit hard, dropped.

For monochrome printers and MFPs:

White:
a) White stripe (usually in the center of the sheet) with fuzzy borders, the width of which increases from copy to copy. Most likely your cartridge is just running out.

b) White stripe with clear borders. The falling of a foreign object into the hopper with toner in the cartridge (it is possible to magnetize a screw, a paper clip to the magnetic roller of the cartridge for HP-Canon); a piece of toner fossilized due to changes in humidity in the same place; a foreign object in the laser unit of the device, perhaps there are cockroaches in it (they like to settle in office equipment on boards).

c) Wide stripes in the picture (background fill) lighter in relation to the main background. the toner in the cartridge is damp; dusting the laser unit.

d) Thin stripes lighter in relation to the main background in the picture (background fill). your cartridge is poorly cleaned.

Black:
a) Black or dark gray stripe (s) grabbing the edge of the sheet with an unclear border.

Black stripes on the right. In this case, this wear is almost maximum. (sometimes it gets worse)

b) Black or dark gray stripe (stripes) not covering the edge of the sheet, but usually from the edge. Overflow of the cartridge waste bin.

c) Anywhere on the sheet, does not capture the edge, from narrow 1 mm to wide 2 cm. There is a foreign object in the cartridge waste bin (a piece of dirt, wool, paper, poplar fluff in summer, etc.); the squeegee of the cartridge waste bin is damaged; cartridge dispensing blade worn.

Left black stripe. A piece of paper appeared in the waste bin for this cartridge.

d) Thin all over the sheet. Drum cartridge wear; the cartridge waste bin is overfilled; cartridge is poorly cleaned.

In this case, the overflow of the mining bin is especially noticeable at the edges.

White:
a) Seven-eight stripes (depending on the diameter of the magnet), usually not wide. Poor contact on the magnetic shaft of the cartridge.

Black:
a) Four stripes on the sheet, bright, with clear boundaries. Contact inside the drum unit in the cartridge is damaged.
four stripes on the sheet are not very bright, with indistinct borders. The drum of the cartridge is lit (the brightness of the stripes depends on the degree of exposure); defect of thermal film (Teflon roller) in the oven of the device.

The photo shows poor contact of the photo roller in the cartridge.

b) Eight stripes on a sheet, bright, with clear boundaries. In the cartridge, the contact of the corotron is damaged.

a) Grayish spots, catching the edge of the sheet, repeating on the sheet 4 times. The drum of the cartridge is worn out.

b) Repeating dashes, spots and dots on the sheet (4 repetitions). The drum in the cartridge is worn out; something sticky has gotten on the drum in the cartridge, and toner has adhered to it (wipe it with a rag with honey alcohol); defect of thermal film (Teflon roller) in the oven of the device.

Here you can see a defect in the thermal film of the HP 4250, although a sticky spot (for example, from champagne) on the photogallery would give about the same effect.

c) Overlay of image fragments, usually all over the sheet (repeating image). Cartridge corotron worn out.

e) Waves when printing gray tones. The toner in the cartridge is damp; mixed toner of different brands (sometimes just different batches); the cartridge dispensing blade is worn out; filled with toner with a higher percentage of iron oxides (observed in HP-Canon cartridges).

f) Gray “worms” of varying brightness anywhere on the sheet, repeated 6-8 times. Mixed toner of different brands (sometimes just different batches); the dispensing blade of the cartridge is worn out; filled with toner with a higher percentage of iron oxides (observed in HP-Canon cartridges).

g) Gray background all over the sheet. The cartridge contains mixed toner of different brands, batches, manufacturers.

h) Brother has splatter-blots all over the sheet, concentrated in a wide strip. The cartridge is poorly cleaned.

i) Toner sprinkles from the cartridge. Poor refueling; cartridge was shaken violently.

j) Faint print. Deterioration of the magnetic roller, wear of the photo cartridge, poor quality or unsuitable toner (including on new compatible or counterfeit original cartridges); dusting of the laser unit in the device, the power of the laser diode in the device has dropped.

In this case, the power of the laser diode has dropped.

k) Blurred image. The gears in the device are erased, the lubricant of the thermal film in the device has dried.

Here the lubricant for the thermal film of the device ran out.

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 that indicates a device malfunction is vertical streaking on the paper. This article will tell you what to do if streaks appear on your printouts.

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:

  • Not enough toner.
  • Laser problems.
  • Drum defects.
  • Defects of the magnetic shaft.
  • Poor contact between the drum unit and the magnetic roller.
  • Incorrectly installed metering blade.
  • Lack of tightness in the cartridge.
  • Overflow of the mining bunker.
  • Failure of the charging roller.

IMPORTANT! If the printer has recently been filled with new toner, streaks may appear during printing due to poor powder quality or improper refilling.

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 normal functioning of the laser is impaired. For correct and long-term operation, experts strongly recommend monitoring the condition of the device by regularly wiping the scanner mirror with a clean and smooth cloth.

Drum damage can 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.

IMPORTANT! The drum unit can be damaged due to improper use of the device, frequent disassembly and poor quality repairs.

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 will immediately offer to replace it if defects are found. The first sign of magnetic roller wear is a gray background of the document and horizontal dark lines on it.

If a single vertical white streak appears all over the page on the printed document, the dispensing blade may be malfunctioning as 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 use 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 thoroughly wipe its surface with alcohol.

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

Streaks of dashes and specks vertically along the page can indicate spilled toner and can be easily removed by cleaning the waste cartridge.

The main reasons and how to eliminate them

A band around the edge can 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.

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 streaks appear on the printout, 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 streak may appear around the edge due to damage to the drum unit, which is a key part of the laser print 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 has not been used for quite some time. To solve the problem, you need to disassemble the cartridge and replace the grease on the contacts.

If the print printer strips and none of the above has helped, then the cause may be damage to the magnetic roller. This is usually indicated by the appearance of horizontal streaks in a dark shade or excessive background. The elimination of the defect is a complete replacement of this part.

A band around the edge can 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 upsets you with the print quality, then check the waste reservoir. it may be full. The presence of such a 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 disturbance 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 very fibers accumulate does not pick up toner and the printed sheet acquires a defect in the form of a white stripe. To bring the seal back to normal it will be necessary to make sure that there is no dirt under the dispensing blade and that it is properly installed. If necessary, clean this part with alcohol or acetone. If the dosage blade is in a badly worn condition, then 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 the malfunction of the cartridge or its contacts in the device. To understand in more detail what to do is out of order, the article about the main defects in printing laser cartridges will help.

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

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 normal functioning of the laser is impaired. For correct and long-term operation, experts strongly recommend monitoring the condition of the device by regularly wiping the scanner mirror with a clean and smooth cloth.

Drum damage can 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.

IMPORTANT! The drum unit can be damaged due to improper use of the device, frequent disassembly and poor quality repairs.

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 will immediately offer to replace it if defects are found. The first sign of magnetic roller wear is a gray background of the document and horizontal dark lines on it.

If a single vertical white streak appears all over the page on the printed document, the dispensing blade may be malfunctioning as 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 use 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 thoroughly wipe its surface with alcohol.

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

Streaks of dashes and specks vertically along the page can indicate spilled toner and can be easily removed by cleaning the waste cartridge.

Problems and design of inkjet ink cartridges

Problems with dried cartridges: In chamber 1, the retaining material is foam rubber, which dries up in the absence of ink. It turns from a soft, permeable material to a hard, poorly conductive material. The ink hardly passes in to the outlet 5, as well as through the baffle 6. Bottom of the ink tanks (HP 178, 655, 564, 364, 920) the outlet is covered by an absorbent pad 5. It also dries up and stops letting ink through after refilling.

This leads to an increase in drag and dropout when printing an image with high ink consumption.

Blockage of air duct 3 and ventilation hole 4 can lead to the same defect. Solution: pierce the sticker over the ventilation hole.

But inkjet printing is especially sensitive to the drying of the gasket 5 in front of the outlet. It is the low flow properties of this gasket that make it as difficult as possible for ink to enter the head. As a result, even a fully filled cartridge cannot provide the required transfer rate. A vacuum is created in the head, due to which air enters it and printing stops. This results in stripes on the page.

Black horizontal stripes with a period

Black, sharp horizontal stripes appear due to poor contact in the photo. We eliminate it by bending the contact, lubricating or replacing the photo roll.

Faulty heads

  • electrical (open or short circuit of control buses)
  • mechanical

The first malfunction (short circuit or open control bus) is usually diagnosed by the printer itself and the printer will not work with such a malfunction. However, this does not always happen, sometimes the malfunction is floating and the printer either works, then detects an error and is blocked.

Mechanical faults include a lack of tightness with the external environment and between colors, as a result of which there may be air leaks or mixing of colors (for example, black in yellow), usually adjacent. This also includes damage to the nozzles. ink passes through them freely, but there is no print. It is obvious that either the chamber or the electrodes are damaged.

Mechanical damage also includes breakage of the head levers that open and close valves in HP D7160, D7355, D7360, D7460 printers and C5180, C5183, C6180, C6183, C7280, C7283, C8180, C8183, C8253 MFPs.

As a result, individual colors stop pumping and eventually disappear. Repair of such a head costs 2,000 rubles. Symptom of this problem: The printer is flooded with ink.

HP printer prints streaking due to cartridges

Gray vertical stripes

Gray or black vertical streaks without repeating may be due to the cartridge. Specifically due to overfilling of the working hopper or wear of the squeegee.

We remove the printer problem by cleaning the cartridge, replacing the squeegee.

Cartridge is out of ink

Most often, the disappearance of colors in the printer occurs due to the fact that the ink cartridges have run out of ink and air enters the head, forming an air lock. If the cartridge is not replaced or refilled in time, the corresponding color channel of the printer will dry out.

Device and head problems HP 940 88 72

Feature of printheads HP 940, 88, 771, 72, 10, 11, 12, 14, 80, 81, 83 is their mandatory initial filling with ink. Otherwise, they will not work, because they have a mechanism for self-regulation of their number. If there is no ink, then there is no regulation. The paint leaves the head, and it begins to dry out, and the pigment in the tubes hardens.

These heads are cleaned only after they are full. Usually the price of cleaning 1 head, which is responsible for 2 colors, is 2000 rubles.

It should be noted that thin tubes can become clogged with a thickened mass of pigment ink. If this happens, the tubes need to be pumped. But this is a long and difficult process.

Pumped cartridges (e.g. HP 940) can contribute to ink system malfunction.

The problem arises when the pump malfunctions or air enters it. If the head dries up, the printer will not be able to clean it. They brought us MFPs with compatible HP 940 cartridges, which had no pump at all. They basically could not work correctly.
