Hello @Vivek9190, and welcome to the HP Support Community!

 

Thanks for posting your question. I'm here to help you get things back on track.

I understand your HP DeskJet Ink Advantage Ultra 4720 is showing an E4 error with a blinking exclamation mark after cleaning, and it's not feeding paper. I’ll be happy to help you resolve this.

What the E4 Error Means:

The E4 error typically indicates a paper jam or paper feed issue. Since you’ve already cleaned the printer, it’s possible that:

  • A small piece of paper is still stuck inside.
  • The paper feed rollers are not engaging properly.
  • The printer needs to be reset after cleaning.

Step-by-Step Troubleshooting:

Power Reset the Printer

  1. Turn off the printer and unplug the power cord from the wall.
  2. Wait for 60 seconds.
  3. Plug it back in and turn the printer on.
  4. Check if the error clears.

Check for Paper Jams Thoroughly

  • Open all access doors (input tray, output tray, rear access if available).
  • Use a flashlight to inspect for any tiny scraps of paper or debris.
  • Gently rotate the rollers with your fingers to ensure they move freely.

Clean the Paper Feed Rollers

  1. Turn off the printer and unplug it.
  2. Use a lint-free cloth lightly moistened with distilled water.
  3. Clean the rollers inside the input tray and rear access area.
  4. Let them dry for 10 minutes before turning the printer back on.

Load Paper Correctly

  • Use clean, wrinkle-free A4 or Letter-size paper.
  • Fan the stack before loading.
  • Do not overload the tray.
  • Adjust the paper width guides snugly against the paper.
