@bls5, Welcome to the HP Support Community!

This seems like an issue with the black ink cartridge or the printhead of the printer. Lets us try these steps to resolve this issue: 

Make sure to use compatible ink cartridges.

For more info on compatible ink cartridges, refer to step 3 of this document

Check the estimated ink levels

On the printer control panel, touch the Ink Level Indicator icon . The control panel displays estimated ink levels.

Make sure none of the ink cartridges are empty. Replace any low or empty cartridges.

Clean the printhead

1. From the printer control panel, open the Setup  menu.

2. Open the Printer Maintenance menu.

3. If necessary, open the Tools menu, and then touch Clean Printhead.

Also, perform step 9 mentioned in this document.

Let me know how this goes.
