Hi @Elvisdeb 

Welcome to the HP Support Community! We're here to help you get back up and running.

The E0 error typically means one or both ink cartridges are unreadable or unusable—possibly due to incorrect installation, compatibility issues, or even failing internal sensors.

Step-by-Step Troubleshooting.

1. Reseat & Inspect Cartridges

Turn off the printer and unplug it.

Remove both ink cartridges.

Check for any protective tape or packaging that's still attached—remove it.

Reseat them firmly until you hear a click.

Power the printer back on to test.

 

2. Clean Cartridge and Contact Points

Use a lint-free cloth lightly moistened with distilled water.

Gently clean the copper-colored contacts on both the cartridges and inside the printer carriage.

Let everything dry fully (about 10 minutes) before reinserting.

 

3. Single-Cartridge Mode (Diagnostic Test)

Remove one cartridge and try printing with only the other (start with color or black).

Swap and test again with the other cartridge.

This helps identify if one cartridge is causing the issue.

 

4. Power Reset

With the printer on, unplug it from both the printer and the wall for 60 seconds.

Plug it directly back into a wall outlet (avoid surge protectors).

Power it on and test again.

 

5. Firmware / Software Check

Use the HP Smart app (or HP’s drivers) to check for firmware updates.

If available, apply updates and restart the printer.

If on Windows, run the HP Print and Scan Doctor utility to diagnose.

 

6. Check for Paper Jams or Tray Overfill

Inspect the paper path and trays for any stuck paper or debris.

Make sure the tray isn’t overloaded.

Clear any jams carefully and test printing again.

 

7. Reinstall Printer in OS

On your computer(s), remove the old printer entries.

Restart the computer.

Re-add the printer afresh—ensure you're connecting to the newly detected printer, not a ghosted or old instance.

Let me know how it goes after trying these steps—and if the error disappears, you’re good to go! If not, we can explore next-level options like printhead checks or external support.
