Stripes when printing with an inkjet printer

This picture can be obtained when the ink supply is poor. 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.

The drum unit 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 rubbed off 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 close 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 continue to print, since the damaged squeegee does not completely remove the powder, and excess toner spills both into the cartridge and into the printer. Urgent recovery required.

Toner Empty

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 the 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 trying to get a few more pages. If the toner is used up, it will not magically appear even from impacts on the table, but the waste will surely spill out of the sump. Waste printing will significantly shorten the life of the product.

Printing stripes. what to do?

Over time, any device can significantly reduce print quality or even block this function, giving a warning about the need for repairs for a variety of reasons. Consider 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 are significantly different.

Stripes when printing with a laser printer

For a complete 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.

Aligning the Print Head

Are the cartridges full, the nozzle test is excellent, but the print is blurry, streaks, fuzzy lines? Another possible reason: the PG is out of gauge.

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 Head” function in the service program and follow all the recommendations.

Waste Toner Box Overflow

Dark dots, dashes or specks are visible along the sheet, which enlarge and merge into a strip as you continue printing. In most cases, this defect is caused by waste toner spilling out of an overfilled hopper. Reason: poor cleaning. Need refueling and preferably use the services of another service center.

Shaft and thermal film problems

If the black stripes are in one place, then pull out the cartridge and inspect the shaft. It deforms over time and this leads to such results. Also, the problem may be due to a foreign object hitting it, removing which, it will be possible to get rid of the stripes.

In addition, thermal film can cause the printer to print like this. It may have been damaged, in which case it is recommended to replace the cartridge with a new one. When removing a cartridge from the printer, watch out for spilling toner. You can determine this yourself. Pull the cartridge out and shake it. If this is the problem, then the hands will be stained with black paint. Here you need to replace the cartridge with a new one, since it is unlikely that you will be able to do something.

HP printer prints with stripes?

The problem of distorted printing sooner or later catches up with every printer user. In the process of printing documents or images, ink is not evenly distributed on the paper, as a result of which vertical or horizontal stripes are formed, which by itself interferes with the normal perception of text.

Of course, in cases where the documentation is not very important, and small stripes do not significantly affect readability, the problem can be ignored. But what about cases when you need to prepare important documents and the finished version of the printout should look presentable? Here you need to determine the cause and try to eliminate it.

Why does my HP printer print stripes?

Many causes of streaking and other print distortions can be identified by their appearance.

Possible reasons why an inkjet printer may strip:

  • poor ink supply (white or colored streaks),
  • clogged nozzles,
  • printhead misalignment (vertical line breaks),
  • contamination of the encoder disk (white stripes located equidistant from each other).

Possible reasons why a laser printer can strip:

  • out of toner (white vertical stripes widening with each new page). how to refill the cartridge,
  • mechanical damage (vertical stripes of different widths),
  • Waste toner hopper overflow (black dots and specks),
  • wear or damage to the drum unit (intermittent black lines along the edge of the page or randomly scattered black dots on the page),
  • problems with the metering blade (dark streaks on the page or faded vertical streaks).

We perform nozzle testing

If you find that the ink tanks are intact, but there are streaks when printing, it is worth performing a nozzle check. To do this, go to Start. Devices and Printers, right-click on the desired device and select Printer Properties from the drop-down menu (if not Win7, then just Properties).

In the window that opens, click Settings, go to the Service tab and there you will find the Nozzle Check button.

On some printer models, such as HP, the nozzle test can only be performed using the buttons on the device. What exactly and how to press depends on the specific model (find out on the manufacturer’s website).

Did you notice gaps on the test page? It is reasonable to assume that the nozzles are clogged and need to be cleaned using the software method.

If unsuccessful attempts to clean, try manual cleaning. This case is quite unpleasant and requires a lot of time and patience when troubleshooting, and in some cases it is better to contact a specialist.

The printer prints with cross stripes all over the sheet of paper

The printer prints with stripes. When printing, cross stripes appear all over the sheet. It should be added that this is the most common printing problem.

  • Waste toner hopper overflow
  • squeegee replacement required.

In this situation, it is enough to clean the waste toner box and the streaks will disappear completely.

Loop check

The print head in a printer is a constantly moving element. Above the parts is a loop, which is responsible for the supply of information and power. If it is accidentally pinched, various difficulties will arise, and streaks may also appear. Therefore, we advise you to remove the top cover of the device and check the position of this element. Take a look at the image below to get an idea of ​​what the required component looks like.

Preventing Printhead Drying

Not all users actively use the printer every day. If it has not been in use for a long enough time, there is a good chance that the printhead has dried out a little. Then you will need to perform software cleaning using the built-in tool at least a couple of times, and you can do it like this:

Left-click on the line of the printer you are using.

Click on the appeared button “Control”.

In the “Maintenance” tab, find “Printhead Cleaning”.

Read the instructions and start the procedure.

Perform this operation two times, and then let the printer stand for at least one hour. During this time, the state of the print head should be restored. If you use the printer very rarely, it is recommended to clean it at least once a week to avoid the final drying of the mentioned element.

Solving problems with printing stripes on an Epson printer

The nuisance in question most often appears due to breakage of printing elements or problems with ink. From this we can conclude that all the reasons are hardware. Most of them are manually solved by the user, but the built-in maintenance tool in the driver can help.

Checking the ink levels

Of course, sooner or later, all cartridges will run out of ink. If a CISS is connected to the printer, it is not so difficult to check the amount of remaining ink, however, the volume of built-in containers is determined a little differently. To do this, you can use one of the driver tools. In our other article, at the link below, you will find detailed guides on this topic. If it turns out that the ink level is too low, you will need to refill the cartridge yourself or take it to a service center.

Checking the cartridge air hole

Each ink tank has a special hole that is responsible for the air supply. The quality of the print depends on the amount of oxygen supplied. If you just connected the continuous printing system or replaced the cartridge with a new one, remove it and check if the hole is clogged or not made at all. If necessary, make it yourself with improvised means.

Solving striped printing problems with an Epson printer

Epson has been actively developing printers for a long time. Devices from this manufacturer are in use by many users. Like all printing equipment, such devices are also subject to various problems, in particular, they are associated with the appearance of defects in printing. As part of this article, we would like to talk about the reasons for the appearance of stripes on finished sheets and options for solving this malfunction, taking as an example a model from the mentioned company.

Eliminating airiness and drying out of cartridges

Sometimes a large amount of air gets into the cartridges by accident or the paint residues in them dry out. These irritants also cause streaks when printing sheets on an Epson printer. This situation can be corrected only by manual cleaning of each container. This is done with detergent or ink punching. You will find all the necessary information and illustrations on this topic in another material below.

READ  How to print small size on a printer

Above, you were introduced to five ways to solve the problem with the appearance of streaks when printing on an Epson printer. It is always recommended to check each of the options to find the right one. However, if all of them are ineffective, one should not exclude the failure of the print head. As soon as possible, contact the service center for specialists to diagnose and further repair the device.

What to do if the laser printer starts to print 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, 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.

Laser fuser

Toner consists of a mixture of shredded plastic and dyes. To stick it to the paper, laser printers use a heating element called a fuser that melts the toner as the paper moves through the fuser rollers. If toner settles on the fuser or the rollers are damaged, you might see unexpected vertical lines in the print. 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 relative to the position of the rollers and other components of the print engine. Some manufacturers only provide these service manuals to technicians.

What to do if the printer prints laser stripes


Toner cartridges. these are the main replaceable parts in laser printers. Exposure to light damages the drums and degrades print quality. Contaminants that enter through the paper can also leave scratches that interfere with correct display. Because print defects can appear at any time, having spare cartridges on hand will allow you to get back to work immediately if your supplies prove to be faulty. Many of the other potential causes of lines and streaks in your exit. especially lasers and fusers. can pose a safety risk to well-intentioned but inexperienced people. If you are unsure of what you are doing under the lid, put the tools aside and leave the work to the expert.

My printer prints stripes | Small Business

Desktop printers contain sophisticated combinations of permanent moving parts and consumables that are 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 depends on the types of output defects you see and the type of printer you are using.

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 foreign toner can result in a leaky cartridge that gradually contaminates your machine, 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 is using depending on your experience and your printer design.

Laser toner or drum cartridge

Laser printers create a full page of content in one go by transferring toner onto paper from a rotating drum and using a heating element to melt the toner. The drum is either part of the toner cartridge or 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 flap that opens when you insert supplies into the printer. If you remove the cartridge and open the flap carefully, 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.

Inkjet print head

Inkjet printers work by heating tiny nozzles or applying electricity to them to reshape them, causing ink to flow onto the page. When you see voids in a print or horizontal lines across it, your print head may have clogged nozzles. Inkjet printers do not tolerate downtime and your head may need to be cleaned several times to remove dried ink. If defects in your output interfere with the appearance of vertical lines on your page content, the print head may need to be corrected. Both cleaning and readjustment use up some of the installed ink, especially if your equipment requires deep cleaning or multiple adjustment cycles.

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 nothing more serious than a nearly empty toner cartridge, a scratched drum, or a malfunctioning toner cartridge. distributed toner. Replacing the cartridge with another should help you rule out the culprit. Vertical white lines can also signal an obstacle that is preventing the laser from displaying pages correctly. Solving this problem may require cleaning the laser assembly or replacing it altogether.

The cartridge is almost empty

Also, if streaking occurs during printing, be sure to check the level of the dye in the print cartridge. To do this, you just need to run a special utility, which is necessarily supplied on the disk in one set with the printer itself. If, according to the results of the check, it turns out that the consumable hopper is almost empty, then you will have to either purchase a new cartridge or refill. After that, the refilled cartridge should stop printing in stripes.


In general, the most common problem that follows any model of printing devices, due to which the printer prints with stripes, is the contamination of the printing mechanism. Therefore, you can first try cleaning the nozzles of your machine. If the nozzles are indeed filled with dried ink, then programmatically clean them. But if several attempts have failed and stripes continue to appear on the printed sheets, then you will have to clean it manually. For more information about possible causes, see the article about stripes on an inkjet printer.

What to do if the printer starts to print with stripes

Often, users of MFPs and printers ask themselves the following question: why does the printer print in stripes? So, if the printer began to print with stripes, then keep in mind that there can be a lot of reasons for such a problem, and if you do not understand anything about the device of such office equipment, then we recommend that you familiarize yourself with our website in more detail or contact a professional for help. Otherwise, you can aggravate the state of your technology, creating additional problems with an illiterate approach.

Let’s take a look at a few of the most common reasons a product might print in stripes. But right away, we note that the reasons that the printer strips depend on the type of device used. Below you will find links to articles related to a specific type of printing device.

Other possible problems

If the device produces stripes that appear in different places each time, then take into account that this problem may lie in the leakage of the cartridge hopper. For example, a mylar film could bend back and waste powder began to pour out from under it, creating a semblance of a vertical strip on the sheet. To check this, you should carefully take out the consumable, and then shake it. But if the printer strips in the same place, then one of the causes of this problem is the shaft of the device, which could undergo deformation during operation. Also, violations could arise due to the fact that some foreign object, for example, a paper clip, got into the printing mechanism. In this case, carefully inspect the cartridge itself and the inside of the printing device. It often happens that when foreign objects get in, the thermal film breaks down. In this case, you will have to completely disassemble the device and make quite serious repairs. When disassembling, remember that some parts of the printer are quite fragile and you need to be extremely careful with them.

But what to do the printer prints with stripes and the above recommendations did not help? It should be noted that such a defect can also appear due to damage to the cartridge due to its dropping. In this case, contacts could be broken or the case damaged. You can solve the problem yourself only by buying a new consumable or by going through and replacing the damaged parts in the old one. But if even after that a strip or line appears on the sheet, then it is possible that toner or ink drops remained inside the cartridge body during refilling. As a result of operation, the coloring matter can get on some parts of the mechanism and thus, even after refilling the cartridge, printing defects will appear on the sheets.

If the printer prints in stripes, what should I do? Another reason for this problem may lie in the contamination of the dispensing blade, which is a part located inside the cartridge. In this case, you need to do the following: disassemble the cartridge and wipe this blade made of a translucent material resembling rubber using a soft cloth previously moistened with a special liquid. Some masters use acetone instead.

If the printed sheet is covered with black streaks, your waste bin may be full. Clean it thoroughly, after which it is advisable to refill the cartridge. Another reason could be damage to the drum unit. in this case, the only thing that can help is a complete replacement. For more information on the causes of streaking when printing a laser printer, read this article.

It would also be nice to refuel with high-quality and expensive dyes. After refilling your machine’s cartridge, try printing a couple of test sheets. But if it is better not to get from this, then perhaps all the problems lie in the printer itself. High-quality diagnostics made by specialists of one of the service centers using the appropriate equipment will help to identify the cause. Of course, in this case you will have to fork out, but it is better to restore the performance of such office equipment than to buy a replacement, which will cost an order of magnitude more expensive than repair.

Laser printer prints in stripes

In this case, a small amount of toner in the cartridge or a defect in the drum unit may be the cause. Therefore, it is best to call a specialist who will refuel it, and at the same time diagnose the operation of the device. If the problem is only a small level of toner and you do not have time to call a specialist, then you can remove the cartridge yourself. Before doing this, it is advisable to cover the furniture and floors, because toner can stain everything. Take out the cartridge and shake it lightly. This procedure is enough for you to print a maximum of 50 pages. In the future, you still have to call the master.

What to do if the printer prints in stripes

Each of us is faced with a huge amount of documents every day. Many work with printers, plotters and multifunctional devices at work or at home. It is quite natural that over time they begin to produce poor quality results. One of these problems is the appearance of streaks in the prints.

Inkjet printer prints in stripes

In the case of inkjets, there may be several reasons. First, ink also runs out. Secondly, due to prolonged inactivity and dye deposition, the print head can become clogged. Thirdly, the printhead ribbon cable may be faulty. Fourth, print head malfunction.

The simplest thing in this case is the low level of the dye. To check this, you need to go into the dialog box of the printing device and find the corresponding tab there. Here you will see which color or cartridge needs to be replaced. If you are using a continuous ink supply system (CISS), it is much easier to control the level. Its transparent ink tanks are always in sight and you can easily refill them.

If the nozzles of the print head are clogged, it is necessary to carry out its prevention. Every inkjet printer has automatic nozzle cleaning. To do this, select the “Maintenance” function in the printer’s dialog box and start the process. After completing the procedure, you need to print a control page. If the situation has not changed, you still have to contact the service center. Most often, this printhead will need to be replaced. But if you urgently need to print an important document, then you can carefully remove the sticker and inject ink using a regular medical syringe. Inject exactly as much as the cartridge is designed for to avoid overfilling.

Reasons why the printer starts streaking

For inkjet and lasers, the reasons may be different, so the situation will also have to be corrected in different ways. Let’s consider each of them.

Methods for cleaning the print head

There are several options for how to manually normalize the printhead. To do this, remove the cartridges and place them in a container with an alcohol-containing solution or 40% ethyl alcohol. Be sure to place the cartridge with the print head down. Leave it in this position for a few hours. After that, it will be necessary to purge.

If the print head is idle for a long time, you need to use another method. Try to hold it 10-15cm above the steam for 10 seconds. The procedure is repeated about 5 times, at intervals, blowing the cartridge with a medical syringe.

If you install CISS, then this problem will not affect you. Thanks to the smooth movement of the ink, the print head is always full and therefore does not dry out. You can also fix this problem by using water soluble ink. They do not form sediment, which is the reason for clogging.

In addition, you can find special solutions for soaking cartridges. There are three types of such formulations:

  • acid. great for HP printhead;
  • alkaline. Suitable for the print head of Epson and Canon printers;
  • neutral.

If you failed to correct the situation, then it is better to contact technical support specialists. The wizards will help you set up the printer’s work, as well as give advice on its effective use.

What to do if the printer prints with stripes

Printers are used by a huge number of people, and often freelancers also need to print something to work. But, as with any technique, some problems can arise with them. At some point, the print quality of the printer declines or you may find that your inkjet or laser printer prints with stripes.

Find out what to do in this case with your own hands, and in which case it is better to send it for repair.

What to do if the printer prints with stripes?

Note that for different devices (inkjet or laser) there are reasons for this kind of problems and methods of solving them. That is why it is worth considering them from different angles and in different sections. If you have a laser printer, you can safely scroll the article below to the corresponding subheading.

While some tips for inkjet printers might be helpful.

What to do if an inkjet printer prints with stripes

If you notice poor ink supply, you should stop printing and refill your cartridge. When there is no ink, do not perform the nozzle test, as this may result in burnout of the nozzles.

In the window that opens, click Settings, go to the Service tab and there you will find the Nozzle Check button.

On some printer models, such as HP, the nozzle test can only be performed using the buttons on the device. What exactly and how to press depends on the specific model (find out on the manufacturer’s website).

Did you notice gaps on the test page? It is reasonable to assume that the nozzles are clogged and need to be cleaned using the software method.

If unsuccessful attempts to clean, try manual cleaning. This case is quite unpleasant and requires a lot of time and patience when troubleshooting, and in some cases it is better to contact a specialist.

If it doesn’t help, then follow the further recommendations.

Aligning the Print Head

Have you refilled the cartridge, tested the nozzles, and the print is still blurry, you notice the blurred print and all kinds of stripes? Try to calibrate the printhead now, as it may well be uncalibrated.

This can usually happen when, for example, you were transporting the printer and there was a shaking, and subsequently the carriage moved. In this case, select “Printhead Alignment” in the same Service tab as in the previous paragraph.

A defect with white stripes at the same distance from each other indicates contamination of the tape or encoder disk. There are different degrees of disc clogging, and this affects how wide the stripes will be.

The encoder can be seen on the left side of the paper feed shaft. It is presented in the form of a transparent circle with markings applied to it. Dashes on the encoder can become covered with dust particles or dry ink particles, as a result of which the sensor does not perceive them, and the sheet is then positioned incorrectly. You should wipe the disc with a soft cloth, having moistened it beforehand, for example, with “Mister Muscle” for wiping Windows with ammonia in the composition.

Note that in no case should you use acetone as a liquid, as the risk of removing the markings on the encoder increases.

An encoder tape and a special sensor are designed for positioning the carriage. In case of contamination of the encoder, parts of the text may go to the side at equal intervals. The ribbon is located along the main sheet feed shaft. It looks like a transparent stripe with lines. It should be wiped with care, as it can fly off the mounts, which will add difficulty.

What to do if a laser printer prints with stripes

But laser printers do not work around the problem, but in this case, most often the problem is associated with a malfunction of parts of the cartridge.

Often, streaking occurs during printing due to the condition of such an important component as the cartridge. If you see white streaks stretching over the entire length of the page, and their width increases with each subsequent print, then it is safe to say that you are out of toner and you need to refill the cartridge.

It is not recommended to shake the cartridge when the toner is used up, as waste may spill out of the sump, as a result of which your cartridge will not last long, printing with waste.

Probably the problem appeared when you accidentally dropped the cartridge on the floor or hit it on a hard surface, remember? If this was the case, it is quite possible that the rubber bands, which retain the powder and have the property of sealing, did not resist the impact. In this case, the toner from the damaged area simply scatters and thereby leaves traces on the paper.

In this case, the longitudinal stripes are of different widths and occur anywhere. With such a problem, repairs are inevitable. over, the cartridge may need to be replaced.

Waste Toner Box Overflow

What if a laser printer prints with stripes? If you notice dark dots, spots and lines that grow and merge into stripes during the printing process? This may indicate that waste toner is scattered from the hopper and may be overfilled. This means that your bunker is very dirty, and you should refill the cartridge using the services of a special service center.

The drum unit is worn or damaged

When the drum is worn out, a black stripe of intermittent appearance appears along the edges of the paper, and its pattern is repeated at the same time. Wear consists in erasing a thin layer of varnish with a sheet with increased light sensitivity.

Mechanical damage to the drum is also possible. There is dust, paper clips, and other foreign objects. So black dots and lines appear, seemingly chaotically scattered over the paper. But they actually repeat themselves more than once.

Toner particles and squeegees can further damage the drum, resulting in increased defects and black streaks, which will definitely reduce print quality. Excess toner is poured into the cartridge and into the printer itself, and the squeegee is unable to remove the powder. Refurbish the cartridge.

Cyan streaks may be visible during printing. This means that the dispensing blade is not installed correctly and is leaking too much toner. Therefore, the cartridge must be refilled correctly.

Also, when the blade is dirty, the gap in some areas of the surface decreases, and the toner is difficult to pass through. Then pale and even white stripes appear in the longitudinal direction. Check how the blades are installed or consult a professional.

Drum and primary charge roller

There are situations when the powder spills out when filling the hopper and remains inside the cartridge. Toner will clog the drum contacts, producing gray streaks. Also, the contacts of the so-called primary charge roller are clogged, which forms black stripes located across the sheet. In addition, the drum begins to wear out, which is why stripes appear at the edges of the sheet.

The damage described above can also occur if the cartridge is overfilled with waste. This is where toner residue gets inside and erodes the roller surfaces.

A few more pressing problems can be seen in the video below. tips from professionals:

In conclusion, we can say that it is easy to see defects, but to understand the nuances is already more difficult. If you do not understand this at all, it is better to show the specialist a page with printing defects. He will determine and give you information on what to do if an inkjet or laser printer prints with stripes specifically in your case.

What to do if the printer prints with stripes?

In offices where you have to print a lot, users of different assemblies of operating systems and different brands of printers and MFPs face the problem when the printer prints with stripes, both white and black. There may be many reasons for this. Most often, this problem occurs due to physical damage to the printer or due to the lack of ink in the cartridge. Let’s consider all the possible options, why the printer prints in stripes and how to fix it.?

Diagnose and solve the problem with printing stripes

If you are using an inkjet printer but have not printed anything for a long time, the ink on the print head may dry out. However, this type of printer has a “Clean Printhead” option. In order to use it, you should follow these steps:

printer, prints, stripes
  • Click “Start” and select “Control Panel”. Go to the section “Hardware and Sound”, “Devices and Printers”.
  • Now click on the name of your printer with the right mouse button and select “Properties”.
  • A small window will open. Go to the “Service” tab and click on the “Print head cleaning” and “Print head calibration” button. You can also use the option “Check nozzle”.
  • The printer will operate for a while (making a whirring sound). The printer needs proof paper available.

IMPORTANT! Older printers do not have an automatic printhead cleaning function. In this case, you need to refer to the instructions of the device and clean it yourself or contact the service center.

If you have an MFP that uses powdered toner for refilling, the cause of the white or black streaks may be due to toner quality or lack of toner. If toner runs out or is almost gone, print quality will suffer.

In order to determine whether the toner is low or not, it is enough to pull the cartridge out of the printer and shake it gently for a while so that the remaining powder from the walls of the inner drum can settle. Next, insert the cartridge and repeat the print. If the streaks disappeared, then the problem lay in the fact that the paint was running out and needs to be added.

As for inkjet printers, the standard program that is installed along with the drivers for the printer notifies that the ink is running out. In this case, you have two options for solving: refilling the cartridge or replacing it.

Also, black streaks on the sheet may appear due to the ink leaking from the cartridge. In order to determine this, it is enough to pull the cartridge out of the printer and shake it over a sheet of white paper. If ink appears, the cartridge will have to be replaced.

A malfunctioning printhead can also cause streaking during printing. In this case, you will have to contact the service center for help, since in some printers the print head is in the cartridge and it is quite difficult to solve the problem with it.

And the last way is to replace the toner. Quite often, printers are refilled with low-quality toner, which affects the print quality. So try replacing the ink and re-printing.

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”.

For HP printers, the desired function is in the software in the “Estimated ink levels” tab, for Epson. “Printer ink levels”.

Run the test with paper inserted in the tray. If there is little ink, a new cartridge is bought or a refill is made.

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 a problem with the print head. For the same reason, poor printing of an inkjet printer 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 the print head” or “Cleaning nozzles”. The start of the procedure, if necessary, is repeated after 5-15 minutes.

On HP you can try through the interface of the installed software on the “Print & Scan” tab. “Service”. “Cleaning the cartridges”.

  • Manual cleaning of the print head built into the cartridge (Canon, HP). The inkwell is placed on a cloth dipped in warm cleaning liquid, nozzles down. After 5-10 minutes. the surface is wiped dry. If after this the stripes have not disappeared, the cartridge needs to 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.

    It is better to entrust the correction of the following problems to the specialists of the service centers. Self-repair without skills can lead to permanent damage to the printer.

    • 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 dampened 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 tape from the carriage, otherwise a complete disassembly of the printer will be needed.
    • The encoder disk is not read. The part has the shape of a wheel with markings applied to it to determine the position of the sheet 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. It is recommended to remove the printer with driver from the system first. Installed from a boot disk or downloaded from the manufacturer’s official website.

    Why does an inkjet printer strip

    What is the reason for the stripes

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

    How to fix

    If the amount of toner in the laser cartridge is low, even white streaks appear on the paper.

    Shaking the cartridge temporarily fixes the problem. A new toner refill will help.

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

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

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

    If it is not possible to eliminate the leaks, a new cartridge is installed.

    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 for two refills, then continuous wide stripes will be printed on the paper.

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

    The width of the stripes is directly proportional to the wear of the coating applied to the shaft. The problem is easy to see by pulling back the shutter. The only solution is to replace the part. If the coating wears out, toner is used up faster and may damage other parts of the printer.

    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 only dirty with toner or a foreign object has fallen under it, cleaning it will help to correct the situation.

    • 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.
    • Extra objects are removed from under the squeegee, and the surface of the blade is gently cleaned with detergent. It is better to clean the sharp part with a wooden stick.

    Sometimes the squeegee can be fixed not with screws, but with glue. Then, after dismantling and cleaning, the blade is fixed with the usual “Moment”.

    Diagnostics by the nature of the stripes

    It is possible to establish the cause, based on the visual display of the stripes, only on a laser printer.
