HP OfficeJet Pro 9720 No longer Printing

[JHobbs]

My printer has gradually lost its ability to print color and no longer is able to print black and white.  The color gradually lost the ability to print bright colors, rather they started to get "muddy".  The black and white only prints a few partial words and streaks.

The ink cartridges all have significant ink left.  The printer is about 5 years old.  Should the printer be fixable or is it wore out?

Welcome to the HP support community.

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

Did you make a copy and check if that prints fine?

Meanwhile:- 

Clean the printhead

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

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

3. Touch Clean Printhead, and then touch Continue.

4. Examine the test page.

   • If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. Repeat these steps for the third cleaning stage, if necessary.

     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.
