Hi @Ggjoy1,
Welcome to the HP Support Community!
Thanks for reaching out about your query regarding error code on your printer!
We're thrilled to have the opportunity to assist you and provide a solution.
If your HP ENVY 6055e printer is showing flashing E and O errors, this usually indicates a printer issue such as a paper jam, low paper, or a cartridge problem. Since you've already checked for paper jams and cartridges, try the following steps to resolve the error:
Hard Reset the Printer
- Turn off the printer and unplug it from power for at least 60 seconds.
- Remove all paper from the tray and reload it properly.
- Reconnect the power cable and turn the printer back on.
Check for Hidden Paper Jams
- Even if you don't see a jam, open all access panels (including the back) and look carefully inside.
- Use a flashlight to check deep inside for small scraps of paper.
- If you see any stuck paper, gently remove it using both hands to avoid tearing it.
Reseat the Ink Cartridges
- Open the printer's ink access door.
- Remove the cartridges and wipe the contacts with a lint-free cloth.
- Reinstall the cartridges firmly.
- Close the door and wait to see if the error clears.
Run a Printer Self-Test
- Press and hold the Wi-Fi & Cancel (X) buttons together for 5 seconds.
- The printer should print a test page. If it prints successfully, the issue might be software-related.
