Hi @aif12 

Welcome to the HP Support Community! 

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

An Error E0 indicates there is a problem with the cartridge indicated by the blinking Ink Level icon.

The left icon represents the color cartridge, and the right icon represents the black cartridge.

Check for an error message in HP software and resolve it by following the onscreen instructions.

If no error is indicated, please follow the steps below and let me know how it goes.

Turn the printer on.

Open the door to access the cartridges.

Wait until the carriage stops moving before you continue.

Remove the cartridge from its slot, holding it by its side.

CAUTION: Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.

Lightly dampen a lint-free cloth with distilled water, and then clean only the copper-colored contacts on the cartridge and the electrical contacts located inside the printer.

Wait 10 minutes for the contacts to dry.

Reinsert the cartridge.

Close the cartridge access door.

If the error persists, repeat the previous steps to clean the cartridge and carriage contacts a second time.
