Replaced Ink Cartiages and now the Black ink won't print .. colour works

Hi @Wendy4000

Welcome to the HP Support Community. I'd be happy to assist you.


Try making a standalone copy in black and check if that works. By this, we can conclude if this is a hardware or a driver issue.

Have you tried printing different types of documents like PDF, Word or Webpages and check if the issue persists?


Let us try these steps to resolve this issue:


Check the ink levels

On the printer control panel, touch the Ink Information icon  to display the current estimated ink levels.


Clean the printhead

  1. On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon .

  2. Swipe the display to scroll to Printer Maintenance, and then touch Printer Maintenance.

  3. Touch Clean Printhead.

  4. 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.


    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.

Also, perform step 13 from this document. Try printing.


Hope this helps! Keep me posted.
