Print quality issue

[fkleroy]

overnight, the printer no longer printed correctly in black. The texts are streaked, even disappear completely in places. I have repeatedly cleaned the printer head at several levels, but the result remains the same. I'm running out of ideas... I saw that there was a lot of black ink in the tank under the cartridge... is that the reason? thanks for your help!

Hi @fkleroy,

Welcome to the HP Support Community. 

I'd like to help!

Step 1: Reinstall the print driver (Windows only)

If you cannot print color from a Windows computer, uninstall and reinstall the printer software. Skip this step if your printer is able to print in color.

Remove the printer from the devices list.

For steps on removing the printer from the devices list, go to Uninstall HP printer software and drivers.

Go to HP Customer Support - Software and Driver Downloads, and then install the latest software for your printer.

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

Step 2: Clean the printhead

The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. Use an automated tool from the printer control panel to clean the printhead.

  CAUTION:

Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.

From the printer control panel, open the Setup menu.

Open the Printer Maintenance menu.

If necessary, open the Tools menu, and then touch Clean Printhead.

A test page prints.

Examine the test page.

If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

NOTE:

If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.

If the print quality is acceptable, touch Done.

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

If the above steps do not, then this may need one on one interaction to fix the issue. 

Update the firmware

Hope this helps! Keep me posted for further assistance.
