Hi @M-Three,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are having issues with the error E0.

An E0 error indicates an unusable cartridge.

This condition occurs when at least one ink cartridge needs attention, is faulty, incorrect, missing, damaged, or incompatible. Reseat both ink cartridges, clean the ink cartridge contacts, restart the printer, and replace one or both ink cartridges if necessary.

Perform the steps mentioned in this document - Ink cartridge errors

Insert one ink cartridge at a time to identify the defective ink cartridge.

Also, make sure the input tray is properly installed, refer to - Replacing Input Tray

Check for any jams inside the printer - E4 (Paper jam) error

Make sure the printer carriage is moving freely. 

Hope this helps! Keep me posted for further assistance
