The widespread computerization contributed to the widespread use of printers, with the help of which it became possible to reduce the number of handwritten documents, replacing them with printed ones. Today, such printing devices are widely used in accounting, scientific and medical institutions, as well as in enterprises of various industries. In addition, they are willingly used in the preparation of essays, term papers and theses by schoolchildren and students.
Common causes of stripes
Printers are reliable electromechanical devices, however, errors and failures occur in their operation. Wherein the most characteristic drawback of these devices is the bands, appearing during the output of information to a hard drive. And in order to understand the reason for their occurrence, one should take into account the difference in the principles of printing of the two most common types of printers: inkjet and laser.
Since the approaches to the method of transferring information from an electronic form to an external medium (usually paper) are different for these devices, then troubleshooting will be done differently.. Currently, printers from HP, Samsung, as well as other well-known manufacturers that use for printing are widely used:
- special quick-drying ink - relevant for new generation inkjet printers and multifunctional devices, for example, the Epson Print Factory series of printers (Epson L120; L355, etc.) or Canon PIXMA series MFPs (Canon MG2440, MP280, etc.).
- fine powder (toner) - used in laser MFPs and printers.
There are many reasons why the printer prints in stripes. . And all of them, as a rule, are caused by contamination and / or wear of the printing mechanisms and their parts. However, each malfunction is characterized by its own type of stripes, which can be: narrow and wide, wavy, monochrome and color, white (unprinted areas), and also consisting of small dashes and dots. They can also be arranged differently on a sheet of paper:
- along or across;
- repeat at regular intervals or appear randomly;
- be anywhere.
What kind of malfunction corresponds to each type of stripe, and what to do to eliminate it in laser and inkjet printers, will be described in the relevant sections.
Inkjet MFPs and printers
When streaks appear on an inkjet printer when printing, it is often caused by the following reasons:
- lack of ink
- violation of the integrity of the cartridge;
- the presence of dirt on the encoder parts (tape, disk);
- print head malfunctions.
To diagnose the problem and eliminate print defects, you must adhere to the following algorithm.
Cartridge out of ink
To combat the appearance of streaks, start by checking for ink in the cartridges. If there are few of them, then the containers are refilled or changed to full ones, without waiting for the ink to run out.
Advice! In situations where it is not possible to visually check the level of remaining ink, you should use the printer management program (“Check Ink Level” function).
As a rule, after refilling the cartridge, the streaks disappear.
Cartridge leakage
If a cartridge leaks, ink spills into the printer. In this case, the parking space of the print head and the rubber squeegee designed to clean it become dirty. As a result, nozzles become clogged at the print head upon contact with soiled parts, and the printer begins to “stripe”. The defect is fixed by washing the parking unit and squeegee special cleaning fluid.
Contamination of encoder parts
In cases where the printer starts to produce sheets or photos with stripes that are located at the same interval relative to each other, the user needs to pay attention to the condition of the encoder parts. These include:
- encoder tape - a translucent film with markings that provide positioning of the carriage;
- encoder disk - a gear wheel on which strokes are applied that determine the position of the paper during printing.
If the tape and/or disk become dirty, the printer will no longer see part of the markup applied to them, and the solid media will periodically slip during printing. As a result, horizontal and/or vertical white stripes (gaps) will appear on the sheet. The defect is eliminated cleaning the surface of parts.
Advice! It is best to clean the encoder parts from dirt with a dry cloth. If this does not help, then you can moisten it with water and repeat the procedure. But after that, you need to wipe the disc and tape dry. The use of cleaning fluid for these parts is not recommended - the markings applied to them may be damaged.
Dried ink
If the printer (MFP) is not used for a long time, then part of the nozzles of its print head becomes clogged with dried ink. At the same time, the device begins to “stripe” when printing. You can solve this problem by activating the following functions in sequence.
- « Nozzle check". This prints a test page to help diagnose the cause of the problem.
- « Cleaning the print head". If necessary, this procedure can be performed several times, with a pause between them, lasting at least 5 minutes.
Important! Program cleaning of the print heads can only be carried out on printers equipped with a special pump (pump). If it is not available, then the heads are cleaned manually using cleaning fluids.
If the printer continues to “stripe” even after program cleaning, the head is washed with a special service liquid. And when Print head built into replaceable cartridges(for example, in Canon MP230, MP250 printers and other manufacturers using FINE technology), you can try to soak the dried ink using cold or hot methods (boiling, steaming, etc.). And in case of severe clogging, ultrasound will be an effective method for cleaning the nozzle heads. However, if even after such radical methods the stripes do not disappear, then the cartridge must be replaced.
When the print head is permanently fixed in the printer(Epson L210, L222, etc.), the nozzles are carefully cleaned with a special cleaning liquid, using a medical syringe with a fine needle and lint-free wipes.
Print head alignment
Sometimes the user may find themselves in a situation where the cartridges are full of ink, the nozzle test result is positive, but there are still streaks on the paper, there are fuzzy lines, and the print is blurry. In this case, the "Printhead Alignment" function, which is activated from the printer's utility program, should help.
Laser printers and MFPs
The appearance of stripes during printing on laser printers is caused by such reasons:
- The cartridge will soon run out of toner;
- the cartridge is depressurized;
- damaged magnetic shaft;
- the waste toner box is full;
- play of the toner dispenser blade;
- photoconductor surface defects;
- poor contact with the magnetic roller and/or photoconductor.
By carefully looking at the stripes on the solid media, you can easily determine the cause of their appearance, and hence the method of troubleshooting. The main symptoms, factors that caused them and ways to solve the problem are shown in the table.
| Type of stripes | Cause |
| White streaks or poorly printed areas began to appear in the middle of the sheet. | This indicates that the toner cartridge is low and will need to be replaced or refilled soon. |
| There are a large number of randomly arranged strips of arbitrary width on the sheet. | Such a defect indicates damage to the body parts of the cartridge. It is recommended to put white paper on the table, remove the cartridge from the printer and shake it over the paper sheet. If toner is sprinkled on it, then the cartridge housing is depressurized and must be replaced. |
| There is a white vertical streak on the printout. | Most likely, a piece of adhesive tape, a paper clip, or another foreign object stuck to the magnetic shaft. It is necessary to carefully inspect the shaft and remove the cause of the printing defect. |
| Across the solid media are faded black stripes. | This defect indicates that the magnetic roller is worn or damaged. Replacing it will solve the problem and those streaks will disappear. |
| During printing, dots and small dashes appear on solid media, which, with further work, acquire the form of horizontal or vertical stripes. | You can get rid of them by cleaning the hopper of toner residues. The same streaks may appear if there is play or contamination on the doctor blade. It must be cleaned of dirt and securely fastened. |
| There are dark streaks around the edges of printed sheets. | A print defect is caused by wear on the sensitive layer applied to the photoconductor. The streaks will disappear as soon as the drum unit is replaced. |
| The print came out of the printer with horizontal streaks of varying hues at the same distance from each other. | The cause of the defect is a violation of the contacts on the photoconductor (gray stripes), or the magnetic shaft (black stripes). It is necessary to clean the contacts, as well as other contaminated parts. In addition, it is advisable to check whether the remaining toner box is full and the condition of the photoconductor surface. If necessary, the identified deficiencies are eliminated. |
Advice! It is advisable to clean the hopper during each refill or cartridge replacement.
As can be seen from the above, in most cases, the cause of the failure of the "streak" printer is determined by the type and nature of the strips. The most common causes are low ink/toner or low print head. But there are more serious problems, however, they can be eliminated on their own, with a certain skill and desire.

Banding during printing is by no means an ornament, but a serious problem that needs to be corrected manually. It will not work if you decide to simply reboot the device. Any printer will strip, sooner or later such an error will occur. Nevertheless, this does not mean that he has come to an end and you need to raise money for a new device. Most often, the problem is easily solved.
However, let's not get too far ahead. First you need to analyze the reasons why the printer can start printing in stripes, and after that we will consider ways to eliminate such a defect.
Your inkjet has started to print in stripes
What could be the reasons that the printer strips:
- One or more ink cartridges are nearly out of ink.
- Because the printer has not been used for a long time, the ink inside the print head has begun to clump.
- Air has entered the print head.
- The air hole in the cartridges was partially blocked.
- The ink line was pinched.
- The head or cable was broken.
- The sensor or ribbon elements are broken or dirty (these are the devices that position the printing system on the sheet).
What can be done to fix the problem?
First, make sure your cartridges are full of ink. If their level has dropped below the minimum, then simply refuel them or replace them with new ones. To determine how much ink is in a cartridge, simply launch your printer management utility and select the "Level Check" mode. You can also find this option using the control panel directly on the instrument. The result will be displayed on your display.
If you have a streak, then carefully inspect the container with the dye. If you are convinced that there are enough of them for printing, you can proceed to the next steps.
If you have not used your printer for a long time, then the problem is most likely that the heads have dried up, the holes through which the ink passes have been clogged with ink mass. There are models of printers for which a long period of non-use is several days, but for most devices this period is from 1 to 3 weeks.
The device will help
Modern printers and MFPs have the function of self-cleaning the print head. The cleaning function is available using a proprietary utility or through the control panel of the device.
For example, in the device management and settings program from HP, it will be called “Cartridge Cleaning”, Epson called this function “Print Head Cleaning”. First you can check the nozzles: if they were clogged, then you can determine this from the resulting print.
The cleaning process can be repeated three times in a row. An hour or two after its completion, the device will be completely ready for operation.
The decision is in your hands
To clean the nozzles from dried ink clots, most modern printers have a special pump. It is worth noting that it is absent in budget versions, so the above methods are completely impossible for them. If you have a cheap printer model, you can also use drastic methods, such as rinsing and soaking the head in a solution with cleaning liquid, or printing using cleaning liquid that has been poured into the ink tank. To use the first method, the head must necessarily be removable or built into the cartridge.
The soaking process consists in immersing the part in a slightly heated cleaning liquid and leaving it for three days. Make sure that the solution does not dry out, it evaporates very quickly, and does not come into contact with the contacts of the electronic components of the devices, otherwise they will corrode. Once the paint clots have been soaked, gently wash them off by spraying the field liquid with a syringe.
Rinsing and soaking slightly reduce print head life. Most often, it is not able to withstand more than three such procedures, so try not to let it dry out too much. As a preventive measure, once every 2 weeks, just start the printer, because when you turn it on, the device cleans the nozzles on its own, preparing them for work. It is worth noting that for the cheapest devices, simply turning it on will not be enough. With them, you will have to do a test print to protect the device from damage.
Expensive repairs
Be very careful not to let the head dry out and streak the Epson printer. The detail of this model is integral to the device, and its cost is very high. The failure of the head in such models will be equivalent to the failure of the entire printer. Repair in such situations will be inappropriate from the side of monetary investments and results.
If you have recently removed cartridges, an air lock may be the cause of streaks. You can remove it with a simple nozzle cleaning. If you have a case where it is not possible to do this programmatically, then bleed the system using a conventional syringe.
The appearance of unprinted stripes on sheets of paper, which also come with a shift in image detail, are often associated with contamination on the encoder strip. This is such a translucent film with markings that is located along the carriage. To solve this problem, you just need to open the printer cover and use a lint-free cloth to wipe the ribbon, after moistening the cloth in the cleaning solution. Once the tape is dry, the machine is ready for use.
All the remaining cases of laser printer streaks, which, fortunately, are not so many, were caused due to hardware failure. If the print head, cables, sensors and other components stop working, then this problem can be solved only by replacing the defective component.
Having problems with a cartridge?
Here are some things that could be the cause:
- Almost out of toner.
- Toner began to spill out of the container due to loose closure.
- The waste bunker is already full.
- A third-party object has entered the cartridge.
- The drum unit is broken or worn out. This is a cartridge component that looks like a cylinder. Toner sticks to it under the influence of LED or laser illumination, after which it is transferred to paper.
- The cleaning blade for the drum unit is defective.
- The magnetic roller is worn or broken. This is the component that charges the toner particles, causing them to adhere to areas of the drum that were previously exposed.
- The roller is not firmly in contact with the drum unit.
- The toner dispensing blades have not been installed correctly. The blade is needed to remove excess toner from the surfaces of the magnetic roller.
- The sealing components of the drum were broken.
- Connection nodes have malfunctions.
The difficulty in fixing the dye on paper is most often due to the fact that the heating and pressure roller of the stove is defective or has been worn out. Difficulties with optics arise not due to a defect, but due to the fact that it was contaminated with dust or toner.
How to determine the cause of the breakdown by the received print?
There are several most likely reasons for the printer to streak when printing; it is extremely difficult to take into account absolutely everything, because models from different manufacturers differ in their design features.
If you have a vertical light streak almost in the center of the sheet, then this is a sign that the toner is almost running out. The less it remains, the larger the streak will be, and the printed documents will be fainter. If there is enough toner, then the defect could appear due to a malfunction of the toner supply system.
To fix such a breakdown, simply replace or refill your cartridge.
Buffer overflow
Does the printer streak when printing with stripes of dark or colored dots that are scattered along the entire sheet? During printing, they may appear in different places. This problem occurs after the cartridge has been refilled and some of the toner begins to spill out. It is also possible due to overflow of the otkhodnik buffer.
To correct this defect, simply clean the cartridge, check its tightness, carefully remove all buffer dirt.
Stripes in stripes that run along the entire sheet and are distinguished by blurry edges? This also happens because the buffer is full. In rare cases, this means that a third-party element has entered the cartridge, it has been damaged, or the squeegee has worn out.
To eliminate it, it is enough to clean the cartridge, free the buffer, or replace the damaged unit.
Perhaps something is stuck?
Does the Canon printer streak with narrow stripes with clear edges, along the entire sheet you can see light stripes that go in a thin line? Most often, the toner cannot get to a certain section of the sheet due to some kind of obstacle. This is caused by a foreign object such as a crumb, coin or paperclip that is caught between the magnetic roller and the cleaning blade. Just remove the extra item and everything will be fine.
Worn Components
Does an inkjet printer streak with fuzzy dark stripes that run along the entire sheet? The reason for this is the wear of the magnetic shaft. To resolve the error, replace the broken assembly or the entire cartridge.
A dark strip appears with repeating elements, can it be located on one or on two edges of the sheets? This error is due to a defect on the surface of the magnetic roller drum or fusing elements. To determine the exact cause, you need to put a blank sheet of paper in the printer and send it to print. When it is halfway through, turn off the printer and remove the sheet of paper. If there are no stripes on it, then the problem lies in the fastening system. If the stripes are present, then the cartridge is junk. To fix the error, replace the broken component.
Other malfunctions
Why does the printer streak with stripes that are irregular in shape and fill the entire space of the sheet with the background? The reason may be that poor quality toner was used for refilling, the magnetic roller was not properly cleaned, or the optical system was dirty. In this case, you need to replace the toner, clean the cartridge, clean the optics thoroughly. It is also recommended to check the position of the dosage blade.
Are the clear transverse stripes at the same distance between each other? The problem may be that the drum contact was broken due to the fact that toner spilled out, the squeegee was damaged, or the waste buffer was full. In this case, clean the cartridge, check that it is sealed, empty the buffer tank, or install a new element to replace the defective one.
Will the HP printer streak with frequent narrow stripes? They arise due to contamination of optical systems. To do this, simply clean the optics.
Will the printer streak with repetitions or overlays of print fragments all over the sheet? The cause of this problem is a malfunction of the primary charge roller. This is the component due to which the surface of the drum is ionized. To eliminate the defect, carefully clean the contacts of the roller, and if this does not help, then you need to replace it.
Computer users may have encountered an issue where streaks appear on printed sheets. In this article, we will answer the questions why the printer prints in stripes and what to do to fix this problem.
Let's look at the very essence of why the printer prints in stripes. First of all, the problem lies in the ink or print head. And depending on the nature of the defects, the root cause of the error can be determined.
Most Common Causes
Let's analyze the main reasons why a color laser printer prints in stripes and what to do in this case:
- Try checking the ink level. In order to do this, in the device maintenance settings, run Checking the ink/toner. If the level approaches a critical level, you should refill the toner.
Sometimes, when the device has been idle for a long time without printing, it may be necessary to clean it. What to do in this case? In the device settings there is an item "Cleaning", which will allow you to clean and solve the problem.
What problems do users face and how to solve them?
Let's analyze the most common situations associated with the appearance of defects in the printing of documents, and what to do with them:
- the most common problem is white streaks that keep getting bigger when printed. This is the simplest and "harmless" option - little toner. When printing repeatedly, the toner runs out and its lack affects the print quality.
Important! Someone advises to shake the cartridge strongly so that the toner is evenly distributed throughout the shaft. This may allow you to print another 10-20 pages, but this should only be done in extreme cases, since the toner is already running out and subjecting the cartridge to such tests, you will shorten its life. If streaks start to appear during printing, it is best to refill the toner.
- Also, sometimes there is a problem that after refilling the cartridge The printer prints in stripes, what should I do in this case? First you need to check whether there is enough toner or vice versa, whether there is an excess of it or whether the toner buffer is not full.
To solve this problem, clean the cartridge, remove excess toner from the buffer.
- When the printer prints with a black stripe along the edge (side) what to do with this problem, all owners of devices with such a malfunction want to know. This situation occurs when you print frequently and for a long time. The cause of this problem is the wear of the photoconductor. And simple cleaning will not help here.
The solution is to replace the photoconductor or cartridge as a whole.
- Wide band across the entire sheet or gray sheet occurs when the toner buffer is full. When the buffer is full, the excess can spill out when printing, so you should always empty it when refilling the cartridge. Also, this problem can occur when a foreign object gets on the doctor blade - as a result of which more toner is printed than necessary.
Solution: Clear buffer, check doctor blade for foreign object.
- Vertical stripes throughout. If they occur each time in a new way, then most often this means that the cartridge is leaking.
Solution: Check the cartridge and sealing rubbers for damage, cracks or gaps.
- It happens that the printer prints with spaces and horizontal stripes what to do in this case? The reason for the black horizontal lines at the same distance from each other is the problem of the shaft and the photoconductor, namely, the contact between them.
Solution: From cleaning the waste buffer and refilling the cartridge, to replacing it. The specialist will be able to determine the cause of the error by the nature of the defects.
If these options did not help, then only the manufacturer's service center - Canon, Epson, Samsung and others will help you answer the question why a Canon printer or any other brand prints in stripes. Some problems can be identified only by familiarizing yourself with the contents of the device, for which you need to have the proper qualifications, so you can’t do anything yourself in such a situation.
Other reasons: cartridge, ink
Basically, all of the above problems were associated with laser printers. Let's also understand why inkjet printer prints white lines and what to do in this case.
The principle of operation of inkjet and laser printers are significantly different. At the moment, inkjet ones are significantly inferior to laser and CISS (Continuous Ink Supply System) in price, speed, resource and other characteristics. But not all users have changed their devices to more modern ones, and this is not required for someone.
Common Causes for Inkjet Printer Defects:
- Lack of ink
- The ink has dried up
- The cartridge seal is broken
- Print head failure
Solutions:
- First you need to make sure that everything is in order with the cartridge - check the ink level, make sure it is intact.
- Check and clean the print head. In the printer settings, go to the "Maintenance" or "Service" tab and select "Cleaning the Print Head".
Have a great day!
During the operation of laser printers, users quite often encounter the problem of reduced print quality, namely the appearance of horizontal or vertical stripes when printing documents.
There can be several reasons for the decline in the quality of laser printing:
- running out of toner;
- problems with the laser;
- photoconductor damage;
- damage to the magnetic shaft;
- violation of the contact of the magnetic shaft and the photodrum;
- doctor blade installed with violations;
- cartridge leakage;
- the mining bunker is full;
- failure of the charge roller.
The reason for the appearance of streaks when printing documents can also be damage to the cartridge as a result of a fall, poor-quality toner, or improper refilling of the cartridge.
White streaks when printed
If the printer prints white streaks, the cartridge may be out of ink or there may be a problem with the laser.
A sign that the cartridge has run out of toner is a vertical white stripe along the entire length of the page, the width of which increases with each subsequent printout. It is important to remember that if the printer runs out of toner, do not remove the cartridge and shake it, these actions will not solve the print quality problem, but may lead to damage to the photoconductor. The way out is to refill the cartridge.
If there is toner in the cartridge, then a problem with the laser may be the cause of the white streaks. For example, getting particles of toner, insects or just dust on the optics. To avoid a defect, you need to regularly monitor the condition of the printer, clean the laser scanner mirror from dirt with a smooth, lint-free cloth.
Image drum damage
The photodrum or photoreceptor is the main part of the cartridge; it is an aluminum shaft with a special coating that can perceive optical radiation. During the operation of a laser printer, the light-sensitive coating is erased, which leads to the appearance of printing defects.
A signal that the photoreceptor is damaged is the appearance of gray-black stripes shifted to the edge of the paper and having a wave-like shape.
The solution to the problem will be to replace the failed part of the cartridge, that is, the photoconductor.
"Streaky print" can also be associated with such a common problem as drying out of the photoreceptor lubricant. The defect occurs when the printer has not been used for a long time. The self-cleaning program "Drum Cleaning", which can be found by going to the "Printers and Faxes" menu, will help solve the problem.
Magnetic shaft damage
The functional purpose of the magnetic roller is to transfer the toner from the hopper to the photoreceptor. The quality of laser printing directly depends on the uniform supply of toner to the photosensitive drum. An excessive gray background or the presence of horizontal dark dashes indicates a deterioration in the magnetic characteristics of the shaft.
The way to eliminate the defect is to replace the magnetic shaft.
Malfunction or wear of doctor blade
The doctor blade is an integral element of the cartridge, by means of which the amount of toner entering the magnetic roller is regulated. The reason for the malfunction of the doctor blade may be the use of low-quality paper for laser printing, this leads to the fact that the villi of low-quality paper stick to the dispenser blade, the magnetic roller cannot pick up ink in the place where the villi accumulate, when printing a document, a vertical white line appears along the entire print page.
To restore print quality, check the correct installation of the doctor blade, if necessary, clean the surface of the doctor blade with alcohol. If a part is worn out, it will need to be replaced.
Violation of the contact of the magnetic roller and the photoconductor
Black transverse stripes may indicate a lack of proper contact between the magnetic roller and the photosensitive drum. The lack of charge between the parts of the cartridge, as a rule, leads to dirt adhering to the contacts.
The solution to the problem is cleaning the cartridge.
Cartridge leak
Streaks all over the page, appearing in different places - most likely the cause of the decline in print quality is the cartridge itself. The first step is to remove the cartridge from the printer. When spilling toner, make sure that there are sealing rubber bands and that there are no mechanical damage to the case (cracks). If there are irreparable defects, replace the old cartridge with a new one.
Overflow of otkhodnik
When toner spills, the first thing to check is whether the Waste Hopper is full. The fact that the otkhodnik is full of used toner is evidenced by vertical stripes along the entire length of the page, consisting of small chaotic dashes and dots. The stripes are usually shifted to the left or right side of the sheet. To eliminate the defect, you just need to clean the cartridge outlet.
Charge roller failure
The charge roller or corotron is a metal rod pressed into a rubber shell, through which the surface of the drum is charged at the initial stage of printing and the latent residual electrostatic image is removed at the end of the cycle. Failure of the primary charge shaft entails doubling of a fragment of text or image.
The following defects can lead to wear of the charge roller:
- contamination of the surface of the rubber shaft;
- electrical breakdown;
- surface wear;
- tears in the rubber coating, punctures;
- change in electrostatic parameters.
To eliminate a printing defect caused by problems in the operation of the primary charge roller, first of all, it is necessary to check the presence of electrical contact on the charging roller, clean the surface. If the described actions did not produce a result, or if there is mechanical damage to the corotron, then it should be replaced.

There are several reasons why a printer may print in stripes. To understand what the problem lies in and fix it, you should start with the simplest. Subsequently, it will be possible to gradually find a breakdown and deal with it.
Cleaning with software
First, start the nozzle cleaning program from the software. It is impossible to single out one algorithm of actions here, since for each model and printer this option is often called differently. However, cleaning must be started programmatically, after which you will need to wait a bit and follow all the instructions. As soon as the operation is completed, you need to print a test page on the printer. This is usually enough to resolve the issue.Refueling
If the above steps did not help, then most likely the ink cartridge has run out of ink and needs to be refilled. In this case, you should find instructions on how to do this for your printer, since the models are different and require an individual approach. After that, you will need to print a test page and see if the problem is solved.Head and nozzles
Sometimes a cartridge streaks because its nozzles are heavily clogged or the head is faulty. In any case, you will need to disassemble the cartridge and troubleshoot. In this case, it is also needed for a specific model. It is important to know that this is necessary periodically, then the problem will not arise.After all, the ink that is on sale, in most cases, lose the original. As a result, they clog the cartridge nozzles and dry out. If cleaning does not help, then the problem lies in the print head. In this case, you will need to take the printer to a service center, since you cannot do it on your own.
Shaft and thermal film
If the black stripes are located in one place, then the shaft should also be inspected. It deforms over time and this leads to such results. Also, the problem may be due to the ingress of a foreign object on it, removing which, it will be possible to get rid of the stripes.In addition, thermal film may be the reason for such printing of the printer. It may have been damaged, in which case it is recommended to replace the cartridge with a new one. When removing the cartridge from the printer, you should see if the toner wakes up from it. You can determine this yourself. Pull out the cartridge and shake it. If this was the problem, then the hands will be stained with black paint. Here you need to replace the cartridge with a new one, so
