Why Is My HP Printer Not Printing Clearly? [Solutions]

If you are wondering “Why is my HP printer not printing clearly?” this article will provide the reasons as well as the solutions to this problem.

HP Printer Not Printing Clearly [Reasons & Solutions]

Your HP printer is not printing clearly due to the following reasons:

1. You are Using Non-Genuine Non-HP Cartridges

To enjoy the best print quality on your HP printer, it is recommended that you use only genuine HP cartridges. When you use non-HP cartridges, you are bound to encounter certain problems and could run the risk of voiding your warranty.

Therefore, if your HP printer is not printing clearly, confirm that you are using genuine HP cartridges. If you are not, replace the cartridges with genuine HP ones.

2. The Automatic Servicing is not complete

When you install a new cartridge into your printer, it is likely that the print quality will not be clear initially. There is nothing you can do about this since your printer will automatically service the cartridge. Hence, the print quality should improve after some hours.

3. Paper Issues

Issues with the loaded paper can cause your HP printer not to print clearly. Therefore, we recommend that you click HP Printer Not Printing Color – Ensure the Right Paper is Used and read the instructions we shared under the “Ensure the Right Paper is used” section.

4. Wrong Print Settings

If the print settings are wrong, your HP printer will not print clearly. To verify that you aren’t using the wrong settings, you need to check the print settings.

We’ve already discussed how to do this here: HP Printer Not Printing Color – Check your Print Settings under the “Check your Print Settings” section.

4. Low Ink Cartridges

The print quality is dependent on the amount of ink contained in your cartridge. Therefore, once the ink level becomes low, it might be the reason why your HP printer is not printing evenly.

Hence, you need to inspect the ink level and you can do this via the HP Solution Center. If the ink is low or even empty after you have checked, you have to replace the affected cartridge.

5. The Cartridges are not Vented Properly and Seated Correctly

If the vents found at the upper part of the cartridge become obstructed or clogged, your cartridge might have issues functioning properly. This, in turn, could cause your HP printer not to print clearly.

Therefore, you need to ensure that the cartridges are vented properly and seated correctly.
