Officejet pro 6978
Microsoft Windows 10 (64-bit)

I am no longer able to print black ink from my Officejet pro 6978.  I have replaced the cartridges twice and followed all of the suggested repairs (using the cleaning features, unplugging the printer, reinstalling the printer app, etc) and nothing works.  What other options are there to repair?

Hi @EBM31972

 

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

 

Please try these steps - Fixing Poor Print Quality

 

If the issue still persists, I'd suggest you Contact HP in your region regarding this. 

 

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.  

 

Have a great day!
