HP Error E0: Ink cartridge problem
An E0 on the number display means one or both ink cartridges have a problem, such as a loose, damaged, taped-over or incompatible cartridge. A blinking cartridge icon shows which one: left is tri-color, right is black. Both icons showing empty while they have ink means a cartridge is not seated correctly.
What to try
- Make sure both cartridges are genuine HP cartridges that are compatible with your printer.
- Open the cartridge door, remove the cartridge shown by the blinking icon, and slide it back in until it snaps into place. Press down any cartridge that sits tilted up.
- Close the door and press Cancel to clear the error. If it stays, turn the printer off, wait 60 seconds, and turn it back on.
- Remove the cartridge again, check the number on its label, and remove any orange shipping tape over the nozzles. Do not touch the copper contacts or nozzles.
- If the error is still there, replace the cartridge with a new genuine HP cartridge. A cartridge still under warranty may be replaced by HP.
When it needs a technician
If E0 still shows with a new cartridge installed, HP says to contact HP Customer Support to service or replace the printer.

First steps for any printer error
- Write down the exact code before you do anything else — similar-looking codes often mean completely different things.
- Power the printer off, unplug it for a couple of minutes, then power it back on. A surprising number of transient errors clear here.
- Open the covers and check for paper scraps, packaging material, or anything blocking the carriage.
- Check the cartridges or tanks are genuine, correctly seated, and not empty.
- Confirm the printer is plugged directly into a wall outlet, not a power strip or extension lead.
- Check your model’s own manual — codes are model-specific, and the manual is the authority for your machine.
