Hi @Steinar3 ,

Welcome to The HP Support Community.  

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

I understand you're facing an "Error 0" on your HP DeskJet 4210e All-in-One Printer, even after replacing the ink cartridges. Here's how you can resolve the issue:
 

1. Check for Proper Cartridge Installation

• Turn off the printer and unplug it from the power source.
• Open the cartridge access door and make sure both cartridges (HP 305 Black and Tri-color) are seated properly.
• Ensure there is no protective tape left on the cartridges.

2. Clean the Contacts

• Turn off the printer and unplug it.
• Carefully remove the cartridges.
• Gently clean the copper contacts on both the cartridges and inside the printer with a lint-free cloth slightly dampened with distilled water or rubbing alcohol. Allow them to dry.

3. Reset the Printer

• Disconnect the power cable while the printer is on.
• Wait for 60 seconds.
• Plug the power cable back in and turn the printer on.

4. Check for Firmware Updates Update the firmware on an HP printer

• If the error persists, connect the printer to your computer and check for any firmware updates via the HP Smart app or the HP website.
