Product: HP OfficeJet Pro 6978 All-in-One Printer

HP Office Jet Pro 6978 no longer detecting any ink cartridges. First I replaced with an off-brand. Then, went and bought a $100 set of HP ink. Same error displaying. Printer says I'm current on updates. I have removed, reset printer and relaunched without fixing. I have also wiped the cartridge and connections with a link free cloth. I have been unable to find a way to talk with a human being via phone. HELP, please.

Hi @CrawshawSarah 

 

Welcome to HP Support Community.

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

It sounds frustrating to deal with the HP OfficeJet Pro 6978 not detecting any ink cartridges. Here are some additional troubleshooting steps to try:

1. Check Cartridge Compatibility

  • Make sure the cartridges you bought are specifically for the OfficeJet Pro 6978 and are genuine HP cartridges, as non-HP cartridges can sometimes cause detection issues.

2. Inspect Cartridge Contacts

  • Check Contacts: Ensure the copper contacts on both the cartridges and the printhead are clean and free from debris. You can use a soft, lint-free cloth to gently wipe them.

3. Reset the Printer

  1. Power Off: Turn off the printer and unplug it from the power source.
  2. Wait: Leave it unplugged for about 60 seconds.
  3. Reconnect: Plug it back in and turn it on.
  4. Reinstall Cartridges: After the printer powers on, reinstall the cartridges to see if it recognizes them.

4. Update Printer Firmware

  • Even if it says you’re current, try manually checking for firmware updates:
    • Go to the HP Support website and enter your printer model to see if any updates are available.

5. Check for Error Messages

  • Look for any specific error codes or messages displayed on the printer that may provide more context about the issue.

6. Test with Different Cartridges

  • If possible, try using a different set of genuine HP cartridges to rule out the possibility of a faulty cartridge

 

I hope this helps.

 

Take care and have a good day.
