Hi @bettina421 

Welcome to HP Support Community.

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

It seems you're encountering an issue where your HP ENVY 7800 series printer is not recognizing the HP 64 ink cartridge as compatible, even though it's the correct type of cartridge for your printer. This issue can happen due to a variety of reasons, including communication problems between the printer and the cartridge, firmware glitches, or issues with the cartridge itself.

Here are a few troubleshooting steps to help resolve the issue:

1. Check the Ink Cartridge for Damage

Ensure that the HP 64 ink cartridge is not damaged or defective. Since the empty cartridge is recognized, the issue may lie with the new cartridge itself.

• Inspect the Cartridge:
  • Check for any visible signs of damage or defects on the new cartridges (e.g., missing ink, cracks).
  • Make sure the protective tape or plastic cover has been completely removed from the cartridge.

2. Clean the Ink Cartridge Contacts

Sometimes, the issue is with the cartridge contacts, which can become dirty or misaligned. The contacts are the copper-colored areas on the ink cartridge and inside the printer where the cartridge connects.

• Clean the Ink Cartridge Contacts:
  1. Turn off the printer and unplug it from the power source.
  2. Remove the ink cartridge.
  3. Use a soft, lint-free cloth or paper towel to gently clean the copper-colored contacts on both the cartridge and inside the printer.
  4. Make sure no ink or residue is left behind, as it could cause further issues.
  5. Reinstall the cartridge and plug the printer back in.

3. Reset the Printer

Sometimes a printer reset can help resolve any errors or issues with cartridge recognition.

• Reset the Printer:
  1. Turn off the printer.
  2. Unplug the printer from the power source and wait for 30 seconds.
  3. Plug the printer back in and turn it on.
  4. Try reinstalling the ink cartridge and check if the error persists.

I hope this helps.

Take care and have a good day.
