Hi @Stevef11871, Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The E0 error on your HP Envy 6065e indicating an "unusable cartridge" can be caused by several factors. Here’s how to troubleshoot it:
Reinsert the Cartridges
- With the printer on, open the cartridge door and remove both cartridges.
- Check for any protective tape on the copper contacts of the cartridges (remove if present).
- Gently wipe the contacts with a dry, lint-free cloth.
- Reinsert the cartridges firmly until they click into place.
- Close the door and see if the error persists.
Restart the Printer
- Turn off the printer and unplug it for 1-2 minutes.
- Plug it back in and turn it on.
- Check if the error goes away.
Check for Firmware Updates
If the printer firmware is outdated, it may reject compatible cartridges:
- On your printer screen: Go to Setup > Printer Update > Check for Updates.
- Or update via HP Smart App (download from the HP website if not installed).
Reset the Printer
If the issue persists, reset the printer to factory defaults:
- Open the Setup menu.
- Go to Printer Maintenance > Restore Factory Defaults.
- Restart the printer and check if it accepts the cartridges.
I hope this helps.
Take care and have a good day.
