Welcome to HP Support Community

Do you have an adequate amount of ink left in all the cartridges?

Let's try cleaning the Printhead

1. On the home screen of the printer control panel, touch the right arrow  to display the second navigation screen.

2. Touch the Setup icon 

   The Setup Menu displays.

3. Touch the down arrow , and then touch Tools.

4. Touch Clean Printhead. The printer cleans the printhead, and then prints out a test page.

5. Evaluate the test page for print quality.

   Figure : Example of the printhead cleaning test page

   

   • If the print quality on the test page is satisfactory, touch No to return to the current print job.

   • If the print quality on the test page is not satisfactory, touch Yes to perform a secondary cleaning of the printhead.

     There are two printhead cleaning stages. Complete both stages if necessary. If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the second cleaning cycle to start the first stage of the cleaning process over again.

Let me know how it goes 

Have a great day 😊
