Why Is My Printer Printing Blurry

The printer prints are blurry with a full cartridge, even after a recent refill, maybe poor-quality consumables, incorrect settings, a breakdown of the cartridge itself, or the device. Each situation is unique and requires a careful approach to its solution. In this manual, we will look at each of the reasons for the blurry of a laser machine and find out what to do and what actions to take in each case.

You at home will be able to troubleshoot and avoid additional cash waste. The instruction applies to any type of printer (inkjet and laser) regardless of its manufacturer.

Why Is My Printer Printing Blurry

When the printer prints are very blurry, any user thinks that the toner in the cartridge has run out. Sometimes this is true, and it is necessary to replenish its stocks or replace the old cartridge with a new one. However, there are several other reasons why the printer prints blurry. Among them:

Low Ink or Toner

The most common cause of blurry printing in laser and inkjet printers may be low ink levels or ink in their cartridges. To exclude this cause, you finally need to check this indicator. For each type of device, the procedure is different.

  • If you have a laser:
  • Turn off the device’s power from the socket or the button on the case.
  • Open the front cover.
  • Take the cartridge out.
  • Shake it several times in a well-ventilated area, or even better outdoors.
  • Please put it back in the printer.

If the print has become a little better after that, you should prepare for refueling.

Instructions for the “Inkjet”:

  • Turn off the power.
  • Open the lid.
  • Take out the paint cans one by one.
  • Inspect them for indicators of paint level.
  • If it is below half, you need to refuel.

How to Steer

A few simple rules should be followed when refueling to avoid problems and malfunctions.

  • Refill only with the correct toner or ink for your printer model.
  • Use original products and consumables whenever possible.
  • If you buy substitutes, then only proven suppliers with positive reviews.
  • When refilling the laser, always empty the waste hopper in parallel.

Poor Quality Consumables

Poor quality ink or toner powder directly affects the appearance of printed sheets of paper. If you notice a deterioration in the visibility of the text of freshly refilled cartridges, then, first of all, check the supplier of your consumables. Alternatively, try dressing with other dyes.

Economy Mode Enabled in Settings

Any printer has a built-in toner or ink saver feature. This mode can enable by the user deliberately or by mistake and automatically by the device itself. As a result, the print will be pale. You can check this and, if necessary, turn off the savings like this.

  • Go through the start and control panel in the section “Devices and Printers.”
  • Find your device.
  • Open its print settings.
  • We are looking for the “Quality” section on the bookmarks or in them themselves.
  • Set to “Standard” or “High” if otherwise specified.

Cartridge Problems

The cartridge of any printing device is directly involved in the printing process. Over time, its parts may wear out or fail.

  • Photoval: The photo shaft has the shape of a long cylinder 30 centimeters and 2-3 cm thick. It is covered with a special green or blue photocell prone to abrasion. In most cases, the edges are more subject to wear, which appear as black streaks. With prolonged use, the coating layer is erasing over the entire surface and can no longer provide its former quality.
  • Dosing blade: This part of the cartridge is responsible for applying the toner to the magnetic roller, which applies it to the sheets. When the blade does not work properly, there are gaps or dull printing problems due to the insufficient amount of power transferred from the dosing element.
  • Magnetic shaft: Directly contacts the photo roller and covers it with toner entirely. If the roller is worn, the ink transfer will not be sufficient to cover all areas of the photoconductor and paper, respectively. Such a “spare part” wears out quite quickly since, for physical reasons, it is not designed for long service life.

Problems with the Oven

Understanding how laser printers work gives you an understanding of why print becomes faded.

The laser beam in the right places changes the charge of the particles on the surface of the drum to the opposite. This is how an invisible pattern of the printed document is applied.

The dosing blade distributes the dye along the magnetic shaft.

The toner applies to the entire photocell but is fixed only in areas with a changed particle charge.

From the photocell, the dye is transferred to the paper.

The high-temperature oven fixes the ink on the paper.

Due to a faulty oven, the ink powder will not bake on the paper and will crumble, resulting in a faint image on the sheet.

When streaks appear on the printed document, the cause may be ink on the top of the fuser roller. Just clean the roller with a napkin or sponge to fix the problem.

Low Humidity

Due to the low air humidity, the oven of the laser printer does not bake the inkwell. It is enough to move the printer to another room, let it stand for several hours in new conditions, and try printing again. If the transfer is not possible, household humidifiers can be used.

Cartridge Cleaning

If the problem persists after refilling the ink completely, but no damage is found in the printer or the cartridge, the reason may be that the ink tank itself is dirty. Remove the cartridge from the printer and gently wipe the nozzles with a clean cloth. If the tissue is not stained or has only faint ink streaks, cleaning is required.

Ways to Clean the Inkjet Cartridge

  • Choice of the cleaning agent. You can buy a special cartridge cleaner from the store or use window cleaner with ethylene glycol or isopropyl alcohol.
  • Training. Take a syringe without a needle, and draw the composition into it.
  • Cleaning. Place the cartridge on a paper towel with the nozzle up. Drop the agent onto the nozzle so that it covers the entire surface.
  • Drying. After 10-15 min. Wipe the surface of the cartridge dry.
  • Examination. Wipe the nozzle again with a clean cloth. If there is no result, apply the following method.


  • The cleanser is poured into a small container. It should cover the bottom by a few millimeters.
  • The cartridge is immersed in the solution for 2 hours with the nozzle down.
  • The part is removed from the product and wiped dry.


  • Take a syringe with a needle.
  • Remove the cartridge and turn it back to you.
  • Find an air intake on its surface.
  • Gently insert the needle into this small hole until it stops.
  • Measure the depth of the hole by making a mark on the needle and cutting off the needle’s excess end.
  • Put on a small piece of thin, durable rubber from the end to its base on the remaining part of the needle.
  • Place the cartridge on a tissue with the nozzle down.
  • Draw air into the syringe, insert the needle into the air intake, and press on the piston until the dye flows out of the nozzle.

Inkjet Printer Problem

So, if a refilled printer does not print well, then a possible cause of such a defect may be a dried-up cartridge. In this case, the paint stops flowing into the nozzles. To verify this, you only need to press a piece of toilet paper or a napkin against the nozzles for a couple of seconds. If there is no trace of the cartridge on the napkin along the length equal to the length of the print head, then the problem is precisely in the dried nozzles. You can learn how to fix this in the following article: what to do if the cartridge is dry. But if the print will view, you will need to clean or refill the data consumable, or both.

If the question of why, after refilling the cartridge, the device prints in a pale color is still relevant for you, then the problem may be burnt nozzles. To solve this problem, try changing the print quality in the printer settings to a higher quality. But if the printing printer does not satisfy the quality of its work, then you will need to replace its consumables. In general, it is not always possible to identify burnt nozzles “by eye”; if the print is bad, but there is a clear imprint on the napkin, then the problem lies precisely in the burnt nozzles.

In addition, a faint tint when printing a refilled inkjet printer may be due to the so-called—airing of its print head. A couple of regular cleanings can be a solution to the problem, after which you will need to wait a while until air escapes through the air holes of the consumable. But this is possible only on the condition that these openings are open but the filling holes are closed. “Paleness” may appear on the printouts even after refilling the consumables of a color inkjet printer. The fact is that in this case, one of the colors is not printed. The reason may be that one of the containers was not refilled or the cartridge head was clogged.

Problem with Laser Printer Printing

If the printer of a laser model does not print well, then, first of all, you need to understand what exactly is meant by the term “bad.” Suppose you mean the appearance of pale or black vertical stripes that form along the edges of the sheet, and you encounter this defect after refilling the device’s cartridge. In that case, this may indicate wear on the consumable phototube. Troubleshooting in this situation is possible only by completely replacing this part. In this case, the cleaning blade must also be replaced, i.e., the squeegee.

In addition, if the laser printer leaves vertical streaks after refilling, the problem may be an overfilled waste bin. The solution to this problem is very simple: you need to carefully pull it out and disassemble it, then carefully clean it, assemble it, and put it back in place.

Suppose your printer leaves white horizontal stripes on printed sheets that repeat at regular intervals. In that case, this may indicate a broken magnetic roller or poor contact between it and the consumable side cover. Solving the problem may require a thorough and painstaking cleaning of the contacts from old powder particles or a complete shaft replacement. In the latter case, the help of a specialist may be required. Otherwise, you may aggravate the breakdown.

If you notice that the printout looks a little lighter than what is shown on the PC display, check the print settings. The fact is that “pallor” may appear due to choosing an economical mode. Other causes of printing defects after refilling the cartridge may be a malfunction of the magnetic roller sheath, doctor blade, squeegee, or photoconductor. In addition, if you use a toner that does not match the cartridge model, a problem such as insufficient print intensity may occur.

If the laser printer prints black sheets, this may result from illiterate refueling. For example, during this procedure, the tanker illuminated the photo shaft under the influence of an artificial light source or sunlight. Perhaps, when assembling the consumable, the charge roller (corotron) was not inserted into its place, or the cartridge contacts were broken. Thus, it is necessary to refill the consumables of a printer of any model with all seriousness and responsibility.
