HP Officejet Pro 6978 will not print black. Cartridge has been replaced and I have done all the suggested remedies but to no avail.

Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- Are you able to make a black and white copy?
- Are you using genuine HP Ink cartridges or refilled cartridges?
- Have you tried to print the Print Quality Diagnostic Page?
Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose the “Copy” option. If the printer is making a good copy, then the printer hardware is fine.
Hope this helps! Keep me posted for further assistance.
