HP DeskJet 2755e

What Is the E0 Error on an HP DeskJet 2755e All-in-One Printer?

The E0 error code on an HP DeskJet 2755e typically appears when the printer is in a setup or alignment state and hasn’t completed the required first-time setup steps. Instead of signaling a malfunction, the E0 code usually means the printer is waiting for you to finish an action before it can continue printing.

On this model, the E0 indicator most commonly means:

  • The printer is not yet fully initialized after being powered on.
  • You may need to load paper, install or secure the ink cartridges, or confirm alignment.
  • The printer is in Wi-Fi setup mode and is waiting to complete a connection through the HP Smart app.

Essentially, the E0 message acts as a reminder that the machine isn’t ready to print until the remaining setup steps are completed.

Common Reasons for the E0 Code

Here are the typical triggers:

  1. Paper not loaded or loaded incorrectly
  2. Cartridges not installed, missing, or not fully clicked in
  3. Printer is awaiting alignment page completion
  4. Wireless setup not finished using the HP Smart app
  5. Printer recovering from a restart and not fully initialized

How to Fix the E0 Error on HP DeskJet 2755e

Try these steps in order:

1. Check and Reload Paper

  • Make sure plain white paper is loaded in the input tray.
  • Adjust the paper guides so they touch the paper stack without squeezing it.

2. Reseat the Ink Cartridges

  • Open the cartridge access door.
  • Remove both cartridges and reinstall them firmly until they click.

3. Complete Printer Alignment

  • If an alignment page prints, place it on the scanner glass and press the Start Copy Black or Color button to complete alignment.

4. Finish Wi-Fi Setup

  • Open the HP Smart app on your phone or computer.
  • Add the printer and follow the prompts to complete wireless setup.

5. Restart the Printer

  • Turn the printer off, wait 10 seconds, and power it back on.

When to Seek Additional Support

If the E0 error stays on the display after completing all setup steps, there may be a firmware issue or hardware-related problem. In that case, reinstalling the printer in the HP Smart app or contacting HP Printer Support is recommended.
