Hi @PattyP21

Welcome to the HP support community.

I understand that you are unable to print in black even with new cartridges. I'd like to help!

Make sure the ink cartridges are properly vented and seated correctly

1.  

Clogged vent

With a straight pin, gently remove excess adhesive from the vent

Unclogged vent

Turn the ink cartridge so that the cartridge contacts face downward, and then match the label color with the color dot on the carriage.

Slide the ink cartridge into its slot, and then gently press the ink cartridge down until it snaps into place.

Then perform a Printer Reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
 

Next Clean the Printhead

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. 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.
