@btmora,

 

Thank you for posting your query on HP Support Community,

 

Let's try these steps here: 

 

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.

  1. From the printer control panel, open the Setup  menu.

  2. Open the Printer Maintenance menu.

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

    A test page prints.

    Example of the printhead cleaning test page

  4. 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.
