The Printer Does Not Print Well Although There Is Ink

Why does the printer print faintly?

A fairly popular question for novice users is why the printer prints faintly. Without going into details, it is rather difficult to give an exact answer to this question, due to the huge number of possible user errors.

Such errors may include incorrect printer settings, the use of graphics programs in which all settings are “default”, the wrong paper type is selected, etc.

For an exact answer to the question of why the printer prints faintly, it is necessary to study the entire sequence of user actions, in 9 cases out of 10 the prerequisite for the faintness of the print is the actions of the novice operator.

Also, a prerequisite for faint printing of images on a printer may be excessive savings on consumables, especially in small offices, where they are trying to save on everything. For high-quality accounting of expenses and income in small offices, it is recommended to use 1C accounting software, which will allow you to adequately look at the cash flows of your company and competently conduct accounting. With a qualitative approach, you can get savings in money without loss in quality.

Another common prerequisite for faint printing is the use of graphics programs. If you work with graphics and send a print queue directly from the program, you should familiarize yourself with the standard print settings, check if everything is entered correctly, make your changes and make a test print. For the convenience of changing and testing print settings from graphics programs, I recommend using color scales and gradients, which can be found freely available on the Internet and downloaded. As an example, you can use the color profiling scale, as in the photo of this review.

Using such a template, you can quite easily and quickly test printing and calibrate the settings to your taste. Believe me, making small adjustments to print settings in graphics programs dramatically change the result of displaying the image that will be printed on paper. We will NOT take into account our usually not calibrated monitor, this is a topic for a separate article.

I have met users who have worked with the program and have been printing for years, and printing photos, but they did not even think that the default print settings were set to medium quality (Text and Images!). I’m not kidding, this is a real example of our client. There is a small salon in our city that provides services for the production of photo souvenirs, in particular, printing photos on mugs. Printing was carried out with sublimation ink on a six-color photo printer. Everything is fine, photo printer, printing photos, but when they first called us for ink refills, I refueled and told them to try to print something for a sample. I was really surprised when I saw that only the main PRINT and OK buttons were pressed when sending to print. The girl did not know anything about the PARAMETERS button, she said that she had never used it! And then we wonder why the printer prints faintly.

The most common mistake of users who complain about faint printing of the printer is choosing the wrong paper type. It should be borne in mind that the standard printer driver contains several color profiles, which are sorted by name for convenience: plain paper, matte photo paper, gloss, super gloss, etc. Using the same image, but choosing different types of paper, the printer generates ink in different ways.

In the case of choosing plain paper, the printer tries to “pour out” as little ink as possible, which is set by the driver, taking into account the low density of the paper and the purpose of plain paper for text, graphics and SIMple drawings. In the case of choosing photo paper, the printer settings, on the contrary, try to “pour” ink on the photo paper as abundantly as possible so that the print is bright and juicy.

A SIMple example: we take a photo and throw it for printing, while forgetting to tell the printer that we will use photo paper, but we ourselves insert the most expensive glossy paper into the printer tray and wait for the result. By default, as a rule, the printer has a parameter. plain paper, respectively, there is an ink saving and our gloss obviously will not be able to its ink norm. As a result, we get the question again. Why does the printer print faintly??

There are many more factors for faint printing, but I’ve pointed out the most common ones in this review. I really want to believe that among the readers of our blog, all users have an excellent level of knowledge in this area and receive only high-quality and bright prints.

Software problems. Physical problems

The reason is in the paper

The paper might not be properly seated in the tray, or a sheet jam has occurred inside the printer. Such problems need to be fixed. Also check if the paper matches the specifications for your printer model. The optimum paper weight for the printer is 80 gsm.

Make sure you loaded the paper upside down in the tray. Photo paper and envelopes have a printable side, but the printable back is NOT intended.

Checking the ink levels

If it is impossible to estimate the amount of ink “by eye”, make a software check method.

  • Go to “Control Panel”. “Hardware and Sound”. “Devices and Printers”.
  • Find the required printer in the list and right-click on it.
  • From the list of options, select “Print setup”.
  • In the “Service” tab, click on “Status Information”.
  • Select the “Data to Ink” tab.

Checking CISS

Sometimes the continuous ink supply system becomes a prerequisite for not printing in black or color. The following problems are possible:

  • NOT translated into working position from transport;
  • Low ink levels in containers;
  • The feed loop is transmitted;
  • Out of ink;
  • Airlock in the ink plume;
  • Ink is dry due to prolonged inactivity of the printer.

There are different ways to solve problems:

  • CISS is transferred to the working position;
  • The ink tanks are placed in the correct position;
  • Air is pumped in the loop, squeezing / kinking of the hoses is eliminated;
  • The head is cleaned by the program method;
  • The page prints and the print quality is checked.

Updating drivers

  • First, the driver for your printer is completely removed. To do this, in the “Run” window (WinR combination) write the command “printui / s”. A window will open where in the “Drivers” tab select the printer and click on “Remove”.
  • Update the software through the device manager. By clicking RMB calling the menu of the icon “My Computer” and select “Properties”, then go to the manager.
  • In the equipment list, left-click on the printer.
  • In the upper horizontal toolbar, select the driver update icon.
  • Do an automatic software update or specify the path to the downloaded driver.

Incorrect cartridge refilling

  • Poor quality paint. Poor ink can be refilled in both black and color cartridges. Paints can only be purchased from an official manufacturer or a reliable supplier.
  • Unsuitable colorant. If the product refuses to print, but there is ink, check to see if it matches your printer model. The dye marking is on the packaging, and the recommendations for choosing ink are in the instructions for the technique. When choosing ink for inkjet printers, you need to take into account that they are pigmented and aqueous.
  • Overflowing ink. When filling the cartridge, you need to pour paints no more than 90% of the total volume. If a color printer smears black on the paper, then there is a problem with the black cartridge, and when it smears, for example, red, it means a problem with the container containing the color dye.
  • The tightness of the cartridge is broken. The container must be pulled out, checked for leaks, if necessary, tape the hole through which the refueling took place.
  • The cartridge is not installed correctly after refilling. It is enough to remove the container from the device and put it back in the appearance with a characteristic click.

Checking the connection

The quality of the connection of the power cable and the cord connecting the printing device with the computer is immediately checked. On the case of the first one, the corresponding button must be turned on. If the connection is made via Wi-Fi, the signal strength is checked. Printer Ready lights should be on.

Clogged, dry ink cartridges or printheads

With intensive and frequent printing without prevention, the ink passage channels in the middle of the cartridge or printheads are clogged with paint, dust or foreign inclusions from low-quality consumables can also get into them. If the printer is rarely printed, the ink may dry out on different surfaces of the device. For any reason, the printer may refuse to print Not only black ink, but also color.

The approach channel is cleaned as follows:

    Go to the printer settings and in the section “Approximate ink levels” Check the amount of dyes in containers.

Cleaning the cartridges must be done one at a time.

A wavy or discontinuous strip is located along the edges of the sheet on one or both sides

This defect occurs when the drum unit is worn or damaged.

The drum is a cylinder covered with a layer of photosensitive varnish. Immediately before printing, the laser illuminates the areas of the drum where the magnetic roller transfers the toner.

With prolonged use, the photosensitive layer is erased into the edges of the paper. When this happens, the drum needs to be changed.

For some reason, it is believed that Epson printers begin to print with such stripes in 3-5 years. It is not. printers of any brand are prone to problems.

You may be interested in this:

If you have an inkjet printer

Unprinted streaks anywhere on the sheet

This is more common when the toner runs out, or when a foreign object such as a paper clip, screw, or a piece of hardened toner gets on the printer shaft. Refueling required.

Why does the printer print in stripes: EPSON, HP, Canon

Why does the printer print in stripes? This is primarily due to the fact that as the printer “ages” the quality of the printed image deteriorates.

One of the most common printing defects is the appearance of stripes on paper. wide and narrow, one-color and multi-colored, horizontal, vertical, located in one place or, conversely, in different.

There are many reasons why the printer prints in stripes. Most often this is trivial wear and tear of parts and contamination of the printing mechanism with ink particles.

However, about everything in order.

Horizontal stripes equidistant from each other

This defect occurs when there is poor contact between the drum unit and the magnetic roller due to spilled toner or an overfilled waste toner box.

Usually it is the result of poor-quality refilling of the cartridge, and sometimes. the result of wear of the printing mechanism assemblies (drum, shaft or squeegee. plate for cleaning the drum).

You can fix the problem by refilling the cartridge or replacing the defective assembly.

Reasons for “striped” printing

Here are the main reasons for streaking when printing with any brand of inkjet printer:

  • Low ink.
  • Ink dried inside the printheads.
  • Print head is airy.
  • The print head is defective or its loop is out of order.

Next, let’s figure out what to do if your inkjet printer starts to print in stripes.

If a laser printer prints stripes

Stripes appear every time in different places

If the laser printer prints stripes all over the sheet of paper or the stripes are always in different places, the problem is most likely in the cartridge.

Take it out and make sure it is hermetically sealed.

If toner spills. check if the sealing gum that traps toner is in place, and if there is any damage on the cartridge case.

If the defect is unrecoverable, replace the cartridge with a new one.


Check the ink levels:

  • Run the printer management utility (if you do not have it, install it from the disk, which was attached to the printer upon purchase or from the manufacturer’s website);
  • Open the section “Service” or “Service”;
  • Run an ink level check.

This is what the Estimated Ink Levels tab looks like in the HP Printer Management Junk

And so. in the Epson printer settings

In continuous ink supply systems (CISS), the level can be assessed visually, since the cans are transparent.

If the ink is low, the cartridge needs to be replaced or refilled.

Clean the print head

The printheads in inkjet printers can reside in the cartridge or in the printer itself.

The first option is implemented in the bulk of Canon and HP models, the second. in Epson.

If you have a printer of the first type, you can SIMply change the cartridge to solve the problem.

In cases where replacement is impractical (the cartridge is completely used up), or is irrelevant (replacing the print head in Epson printers is comparable to the cost of buying a new printer), you can try to solve the problem by cleaning.

At home, it is best to do this programmatically:

  • Insert a sheet of paper into the printer, run the management utility and open the “Maintenance” (“Service”) section.
  • Clean the printheads and check nozzles (nozzles or, in other words, “spray guns” from which ink comes out). These options are available in service programs for printers of any brand. Here are some examples:

If you have CISS, Make sure that the holes through which air enters the cans are free. If filters are installed in them, check if they are dirty.

If air passes through the filters with difficulty, they must be replaced or removed.

Cleaning the printheads also helps in case of airborne air, which happens after changing or refilling cartridges.

Make sure the printheads are working.

If cleaning, including manual flushing with liquids, does not solve the problem, most likely the head or related parts (loop) are out of order.

Breakdowns of the printing mechanism often occur due to careless handling during removal, and sometimes spontaneously, especially if you often and a lot of print.

Only the replacement of the faulty part will help to fix the problem.

Why is it easier to solve this problem when a Canon or HP printer prints in stripes? Because, as we said, the printheads in them are located in cartridges.

You just need to replace the cartridges with new ones.

However, remember that their price can be 50-90% of the cost of the printer. The high cost is explained by the fact that the print head is much higher than the ink capacity.

In the event of a breakdown of the printing device in Epson or in another model with a print head in the printer itself, you will have to contact the service.

The product does not print in black

Some users may face a problem when the printer does not print well with black, or does NOT print with it at all. Such a malfunction can be easily solved in most cases on your own, without the help of specialists.

Possible causes of the malfunction

Incorrect selection of cartridges, or cartridges from different kits may not work correctly in the printer. This also swings ink. they can thicken too quickly or clog the nozzles.

  • Ink cartridges are low on ink.

Some printer models do not work well with cartridges that contain a small amount of ink. It is in such cases that black color will not be completely absent, remaining pale and indistinct on prints.

  • Clogged Printhead or vents in the cartridges.

Sometimes the product does not print in black due to airborne printheads or clogged vents in the cartridges.

How to fix problems

It is important to carefully select compatible consumables, purchasing them from trusted manufacturers, and also to prevent the joint operation of cartridges from different manufacturers.

If there is insufficient ink in the cartridges, they must be refilled or replaced.

The printhead problem is Most serious and requires cleaning. To do this, you can use the hardware method by selecting the appropriate command in the printer menu. With prolonged downtime of the device, manual cleaning will be required, which requires care and certain skills. Sometimes if the printer does NOT print in black, clogged vents are to blame. After turning off the printer, remove the cartridges and carefully clean them with a pin.

How to set up your printer correctly?

But what if the printer is connected correctly and the tenth reboot hasn’t helped? Then you have to go into the settings:

  • Go to «Control Panel»Go to the category«Hardware and Sound“.
  • This is where we are expected “Devices and Printers“, Whose settings we will change.
  • The printer icon is familiar to everyone, it is enough to name it with the left mouse button twice.
  • After that, a small window will open in front of you, in which you should select “Printer“.
  • In the context menu that appears, you need to figure out where we will put the checkmarks, and where it is better to remove them.
  • Use as default“. The function is useful, it is better to put it on. If two or more printers are connected to the computer at the same time, this will start printing by default.
  • work autonomously“. NOT a useful function at all, but “Pause printing“And even worse. It is because of the presence of a jackdaw at this point that the printer may NOT work.
  • There is also one very useful function in the same menu. You can use the item “Clear queue»And all the documents put on the printout will disappear from memory. It is extremely convenient if by mistake you started printing several hundred or even thousands of unnecessary pages.

The software is the same, except without the media.

6 reasons the printer stops printing

Problems with printing pages can be caused by various reasons:

  • Dried or improperly distributed ink on toner.
  • Software crash.
  • Lack of drivers for the newly installed printer.
  • Problems with the USB cable connection.
  • Incorrectly set settings on the computer.
  • Technical malfunction of the device itself.

In any case, you should not immediately run to the nearest service center. If the problem can be solved in a couple of minutes, it is not yet a fact that you will be charged an acceptable amount for solving it. And if you urgently need to print important information, somehow it’s not at all before the search for specialists.

When things go wrong, you need to try to contain your anger and aggression. It is enough to think about why the device does not print, although there is ink and how it can be fixed. If the owner regularly monitors his equipment, malfunctions occur much less often and are eliminated faster.

Fixing cartridge problems

If you are using NOT an original cartridge, whether you fill it yourself or by some craftsman, problems may arise even with sufficient ink levels. Of course, the easiest way out is to take a new cartridge each time or take it to a service center for refueling. But if this option is not affordable, you can solve problems as soon as they arise.

AT laser printer ink may not be properly distributed in the compartment, so just pull the cartridge out of the printer and shake it well. Repeat several times, until the performance is fully restored.

If inkjet printer, the problem more often occurs in the drying out of the ink itself. A little water or alcohol will help here, soak a cotton pad or swab with them and wipe the contacts.

But before you start “shamanite” you should make sure that the cartridge itself is installed in the compartment correctly. Check if it is protruding from it, and if the contacts are not moving away. Try to remember how the equipment looked before, what has changed in all this.

Most of all, it pisses me off when everything seems to be in order, but nothing works. It is unclear why the device does not print, although there is ink, and all the settings seem to be set? But the devil is always in the details, a couple of missed checkmarks and that’s it, the printing device refuses to work.

Why did the printer stop printing?

All problems with printers can be roughly divided into four groups:

  • Problems connecting the machine to the computer.
  • Errors in settings and NOT installed drivers.
  • Out of ink in a cartridge.
  • Incorrectly refilled or installed cartridge.
The Printer Does Not Print Well Although There Is Ink

Searching for a problem every time again is not a pleasant experience itself, and it will take a lot of time. Therefore, it is easier to remember a SIMple aLGorithm of actions.

The first step is to check if the printer is turned on at all?

  • Pay attention to the lit indicators on the device panel.
  • Check if the machine is plugged in.
  • Make sure the USB cable is plugged in and functioning properly.

Sometimes a SIMple restart of the computer and printer is enough to restore the printer to work., it solves 90% of all auto products problems.

When restarting, some of the settings are reset, and some temporary files that could slow down the system are deleted. So it’s enough to press two buttons and wait literally a minute.

How to check ink in a printer

Technically speaking, checking the ink supply is nearly impossible. You will have to use the software and available equipment:

  • In the tray (bottom right corner) you will find your printer icon.
  • It should be double-clicked with the left mouse button.
  • If there is an icon, open “Start“And go to”Control Panel“. After 10-15 seconds of searching, you will find another icon “Devices and Printers“.
  • In the newly opened window, you can easily find your printer, which you also need to call twice.
  • Depending on the manufacturer’s firm, you will need to go either to “Settings“, Either in”properties“.
  • Further “function“Or”service“. After going to “printer services», You can find information about the amount of ink in the cartridge.

Special programs for these functions are NOT developed, because the printer will always give a signal to reduce the amount of ink. But check your utilities, perhaps some of them give information about the status of the cartridges of your printing device.

Lesson: Fixing a Printer Problem

Further, Viktor Efremov, a specialist in office equipment, will talk about how to fix the problem with non-printing printers with a full ink cartridge:

The integrity of the cartridge is broken

Mechanical damage can occur for various reasons, as an option due to inaccuracy during the next refueling or assembly. If in inkjet technology cartridges are damaged quite rarely, then in laser printers cartridges can affect printing Not only due to damage, but also due to improper assembly.

To check for damage, remove the cartridge and shake it in a place far from things, objects that can get dirty. Shake outdoors is best. If powder falls out during shaking, it means that the tightness of the cartridge is broken.

Cleaning methods

First, the printer is always given the opportunity to clean its components from the program itself. In some cases, this method helps to make printing better, to restore the quality to the previous level.

For Canon printers, the cleaning functions are found under the Maintenance tab in Printer Properties.

Do a regular cleaning first, then a deep clean if the first step did NOT fix the seal.

Therefore, there is only one recommendation here. We always install a full set of drivers on the computer from a disk, which comes with the equipment, or download the software from the manufacturer’s official website. If the necessary settings described in the article are available in the properties of the device, then look for the reason in the absence of the necessary driver or run proprietary software, inside the interface of which, most likely, you can perform the necessary actions.

When there is an exact certainty that the program method did not give results, it is necessary to switch to the manual one. The actions depend on the type of print head, which is built into the ink tank (typical for Canon and HP brands), and removable (Epson printers).

Instructions for the built-in head. Open the printer cover. Move the cartridge cradle to the center position. Take out the containers. Pour some cartridge cleaner into the syringe. Drop on nozzles, wipe dry, presses a little. Check the print by leaning the nozzles against a tissue.

If the trace has not become clearer, then you need to soak the head in liquid. Collect flushing fluid in any level container. Dip the cartridge, nozzles down, directly into the liquid for a while.

Then, dry the nozzles with a napkin, place the ink tank back into the carriage and try to print. In addition, software cleaning is started. You need to pour a little liquid into the vessel. Cartridge contacts Must be in contact with the product.

If the described methods are ineffective and there is an indistinct trace, you can try to purge the cartridge. Remove the needle from the syringe or shorten it at least halfway. Insert carefully into the filler hole. Push the syringe plunger in firmly to create pressure inside the container, which will squeeze out dry dried ink.

An extreme option is to soak for the whole night, after which, in case of failure, buying a new cartridge is almost inevitable.

Instructions for heads that are detachable from cartridges. All ways are SIMilar.

  • Maceration. Draw the cleaner into the syringe. Drop on each fitting several times. The cleaning time depends on the degree of soiling or drying. Mild cases are resuscitated in a couple of hours, difficult for the whole day. You can put tubes on the fittings and draw up liquids in them, so that rinsing is done independently.
  • Flushing. Place the head in a plastic lid or short jar. Slide tubes of suitable diameter onto the fitting. Remove the needle from the medical instrument and insert the end of the syringe into the tube. Gently start to press in the piston. As a result, the liquid should start pouring into the container through the steam generator. It is necessary to rinse until the natural color cleaner is poured out.
  • Broach. Proceed SIMilarly to the previous one, only pour the cleaner into the lid, and with an empty syringe pull it through the head (pull the piston towards you).

When Consumables May Affect

  • Fake or non-original consumables. If the cartridge is filled with non-original ink or toner, then print deterioration is NOT the worst thing that can happen. Counterfeits or poor quality dyes can damage the second parts of the printer. You can only purchase consumables that are fully suitable for a particular cartridge model. It is better to use only original materials. Compatible ones are also allowed, but the quality of the printed image is likely to decrease.
  • If at some point you decide to change the manufacturer of consumables, then before refueling, be sure to do a complete cleaning of the cartridge and head. Mixing two different consumables can lead to chemical. Reactions between them. This is due to the introduction of various components in production, which can give a reaction when interacting.

After changing the manufacturer, it is advisable to update the color profile. This is done using a file, which contains information on the exact proportions for mixing different ink colors in order to get the desired shade when printing. The file is available for download on the manufacturer’s official resource.

Inkjet printer prints poorly

A common cause of poor print quality in inkjet printers is a problem with the cartridge. If you DO NOT print for a long time, then the ink dries up, so when you resume printing, the result may not be at all. At best, you will see various defects on the sheet. blur, streaks, gaps, and the like. Both black and white and color cartridges can dry up and fail.

  • Remove the cartridge from the machine.
  • Take a white clean tissue or paper towel. On the underside of the cartridge is the Printhead, which contains nozzles (nozzles). During printing, ink is released onto the paper. Blot the head with a napkin.
  • If you see a distinct ink mark, then everything is fine with the cartridge, the ink has not dried. A colored ink bottle should leave a trail of three colors. yellow, blue and red.
  • If there is no normal ink trace, you need to clean the printer’s print head using one of the possible methods. Software or physical with the introduction of flushing fluids. The latter is used in advanced cases when software cleaning does not help and the cartridge is dry or clogged up.

The removable head of the printer (Epson) or the continuous ink supply system (CISS) most often gives poor printing in one color. For CISS, an actual problem may be the formation of an airlock in the loop, and for the head. all the same drying of paint or clogging. In the first case, air is expelled from the tube of a certain color, in the second, flushing is done, first programmatically, and then manually with cleaning agents.

Economy Print is on

Although there is ink (ink) or toner in the printer, it may not be enough or the fill level may be approaching zero. In this case, some printer models may automatically turn on the so-called save mode when the print quality decreases. By saving dye, it turns out to print more sheets on the “last pairs”.

It is recommended that you check this problem first, especially if you see less than half the ink level when checking the remaining ink levels.

Open the Devices and Printers window. To do this, execute the command “control printers” in the window, which must be started with the key combination “WindowsR”.

Find the printer you want. Click on the icon with the right mouse button and in the context menu select “Print settings”.

The printer settings menu appears depending on the model. Switch between tabs to find quality settings. Some printers may not have this function and settings at all. It all depends on the specific manufacturer and model.

On the example of the Canon brand, you can see that the “Home” tab has the necessary settings.

What to do if the printer does not print well, although there is ink in the cartridge

Any change in the print quality on the paper can be a sign of poor printing. For example, a picture or text becomes blurry, some part of a letter or all print is blurred. A printer of any manufacturer (HP, Canon, Epson, Brother and others) can print poorly.

Let’s figure out why the printer does not print well, although there is ink. What to do to diagnose and fix the problem when only black is printed poorly.

Poor printing on a laser printer

A printer with laser printing technology has a completely different design and printing principle. At a minimum, there are many rotating elements that can wear out and affect the final result of the printed information. Each element can give a certain printing defect.

After a long downtime, even if all the elements are in good working order, the laser device may start to print poorly. Alternatively, the toner is empty. In this case, you need to take out the cartridge and shake it well with your hands. The toner will be evenly distributed inside the cartridge and the printing will resume the previous quality.

  • Vertical black streaks across the entire height of the letter on one or both edges indicate damage to the drum unit. The photosensitive layer can be damaged over time, which is externally visible when inspecting the part. If damaged, the shaft is replaced with a new one. Additionally, it is better to put a new cleaning blade (squeegee). Stripes are flat and wavy.
  • Horizontal equidistant black stripes indicate that the waste toner bottle is overflowed. powder that was not used during the previous specified printing. The waste hopper must be cleaned according to the rules during each filling. The situation can occur when printing too often, when the laser cartridge was refilled several times, but attention was NOT paid to the hopper.
  • The magnetic roller, when worn, can fade the print, give out white heels or gaps on the sheet of paper. Even if you are satisfied with the print result, it is best to make a replacement to avoid damaging other parts of the printer. It is also recommended to check the contact of the photo roll with the magnetic.

Cleaning the feed rollers

The feed rollers feed the paper through the printer after a print job is sent. Over time, mechanisms can become dusty, dirty or even worn out. In the latter case, the easiest way is to replace the rollers with new ones, there is nothing complicated about it. To understand if the rollers need replacing, you need to inspect the part. The entire rubber surface of the part must be rough. If there are any gaps, smooth areas, and even more so when the printer does not pick up paper well or does NOT take sheets from the tray at all, then the rollers need to be replaced.

If dirty, you can do a SIMple cleaning.

  • First, look for the option to run the cleaning through software. In the example shown at the beginning of the article with a Canon printer, such a function is.
  • Otherwise, or if the software did not remove the contamination, remove the dirt from the roller using a cotton swab moistened with water or a napkin. Act gently without brute force.

Perhaps the article does not cover everything in a situation that can satisfy you. Therefore, the site contains separate thematic articles on each issue.
