[warmask]

My Envy Pro 6452 is showing error code E4. Internet says its a paper jam. I have reset the printer, pulled out every tray and part that comes out. There is no paper pr debris stuck anywhere. When I reset it, it doesnt even try to feed any paper through. not sure what to do.

Hi @warmask,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

The E4 error code on your HP ENVY Pro 6452 All-in-One Printer typically indicates a paper jam, but as you've noticed, it can sometimes be a false jam, especially if the printer doesn't even attempt to feed paper.
 

Here are a few steps to try and fix the issue:

1. Reset the Printer

• With the printer powered on, unplug the power cord from the back.
• Wait 60 seconds.
• Plug it back in directly to a wall outlet (not a surge protector).
• Turn it on and see if the error clears.

2. Check All Jam Locations

Even if you don’t see paper, check these areas carefully:

• Input tray: Remove all paper and check for small scraps.
• Output tray: Pull it out and inspect underneath.
• Cartridge access area:
  • Open the ink access door.
  • Wait for the carriage to move.
  • Turn off the printer and unplug it.
  • Move the carriage manually left and right.
  • Look for any debris or stuck paper.
• Paper path cover (behind the cartridge area):
  • Pinch the tabs and lift it out.
  • Check under the flip gate and around the rollers.
• Bottom cleanout door:
  • Turn the printer over.
  • Open the cleanout door and check for debris.

 If the Printer Doesn’t Attempt to Feed Paper

This could indicate:

• A sensor failure (thinking paper is jammed when it’s not).
• A mechanical issue with the rollers or carriage.
• A firmware glitch.

Try This:

• Press the Cancel button on the printer to attempt to clear the error.
• Update the firmware using the HP Smart app or from the HP ENVY Pro 6452 support page.

I hope this helps.

Take care, and have an amazing day!
