Hi @JoeyS1952,

Welcome to the HP Support Community. 

I'd like to help!

Appreciate the steps you performed. 

Let's try the steps below and see how it goes. 

Step 1: 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.

On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .

Swipe up on the display, and then touch Printer Maintenance.

Touch Clean Printhead, and then touch Continue.

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.

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