@Topcat72, Welcome to HP Support Community. 

 

Thank you for posting your query, I will be glad to help you. 
The E0 error code on your HP DeskJet 4252e typically indicates an ink cartridge issue, which can prevent the printer from scanning or copying. Here's how you can resolve it:

Check Ink Cartridges

The E0 error often relates to one or both cartridges being:

  • Improperly installed
  • Low on ink
  • Not recognized by the printer

What to do:

  • Open the ink cartridge access door.
  • Wait for the carriage to stop moving.
  • Remove both cartridges.
  • Gently clean the copper-colored contacts with a lint-free cloth and distilled water.
  • Reinstall the cartridges firmly until they click into place.

Note: Make sure you're using genuine HP cartridges. Non-HP or refilled cartridges can sometimes trigger errors.

Reset the Printer

You’ve already tried unplugging, but let’s do a full reset:

  • With the printer on, unplug the power cord from the back.
  • Wait 60 seconds.
  • Plug it back in and turn the printer on.

Check for Firmware Updates

Outdated firmware can cause unexpected errors.

Run HP Smart App Diagnostics

If the issue persists, use the HP Smart app:

  • Open the app on your PC or mobile device.
  • Select your printer > Printer Settings > Advanced Settings > Tools > Diagnose & Fix.

Try a Copy Test

After the above steps:

  • Place a document on the scanner glass.
  • Press the Black or Color Copy button.
  • Check if the printer responds without blinking or showing the E0 code.

I hope this helps. 

 

Take care and have a good day.
