Hi @Grace1441 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

An E0 error on an HP printer indicates a problem with the ink cartridges, typically that they are unusable, faulty, or incompatible. This could be due to incorrect installation, damage, or communication issues.

Troubleshooting Steps:

1. Reseat the Cartridges:
Open the printer, remove the ink cartridges, and then reinstall them, making sure they are properly seated.

2. Clean Cartridge Contacts:
Use a slightly damp (not wet) cloth or cotton swab to clean the gold contacts on the ink cartridges and the corresponding area in the printer carriage.

3. Power Drain:
Unplug the printer, wait a few minutes, then plug it back in and power it on. This can help reset any communication issues, according to one post.

4. Check for Compatibility:
Ensure you are using the correct ink cartridges for your specific HP printer model.

5. Replace Cartridges:
If the issue persists, replace the ink cartridges with new, genuine HP cartridges.
