Hi @Dynasty2,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing a cartridge error with your HP OfficeJet Pro 6978 All-In-One Printer, follow these steps:
 

Check Cartridge Compatibility:

• Ensure the ink cartridges are compatible with the HP OfficeJet Pro 6978.
• Verify that you have correctly installed HP Instant Ink cartridges.

Reinstall Cartridges:

• Turn off the printer and unplug it.
• Remove all ink cartridges.
• Inspect the cartridges and the contacts inside the printer for any dirt or residue. Clean if necessary with a lint-free cloth.
• Reinstall the cartridges, making sure each clicks into place.
• Turn the printer back on and check if the issue persists.

Update Printer Firmware:

• Ensure your printer's firmware is up to date. Connect your printer to the internet and check for firmware updates via the printer's settings menu. Update the firmware on an HP printer

Reset the Printer:

• With the printer on, unplug the power cord from the back of the printer.
• Wait 60 seconds.
• Plug the power cord back into the printer and turn it on. This can sometimes reset the internal sensors.

Run Printer Diagnostics:

• Access the printer’s control panel and navigate to the "Tools" or "Maintenance" menu.
• Run any available diagnostics or cleaning cycles.

Check HP Smart App:

• Use the HP Smart app or HP Printer Assistant software on your computer to check ink levels and get more detailed error messages.

I hope this helps. 

Take care and have a good day.
