Welcome to the HP support community.

I understand that you are getting print quality issues, I am glad to assist you.

Clean the printheads

Clean the printheads from the printer control panel if you find defects on Test Pattern 2. Only evaluate the left side of Test Pattern 2.

NOTE: 

If you did not find defects on Test Pattern 2, skip to the next step. Unnecessary cleaning wastes ink.

Test Pattern 2 with white lines

1. On the printer control panel, swipe left, and then touch Setup .

2. Touch Tools, and then touch Clean Cartridges.

   A Cleaning cartridges message displays, and the printer prints a Print Quality Diagnostic Page.

3. Examine the page.

   • If Test Pattern 2 is free of defects, continue to the next step.

   • If Test Pattern 2 still has defects, touch Yes to proceed to the second-level cleaning.
