Envy 4520 keeps jamming after clearing the jam

[SherLoch]

I keep attempting to print a document, but the printer keeps jamming. I've opened the printer, removed the jam multiple time. I am not able to see any obstructions, but it keeps jamming. Any suggestions?

@SherLoch, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

That sounds incredibly frustrating! 😩 If your HP ENVY keeps jamming despite clearing it multiple times and finding no visible obstructions, there are a few things worth checking. 

Sometimes, tiny bits of torn paper get stuck deep inside the rollers, so using a flashlight to inspect every corner, including the rear access area can help. 

Even if there’s no paper, dirty rollers might be the culprit. Try cleaning them gently with a lint-free cloth and a bit of distilled water or rubbing alcohol, then let them dry completely before trying again. 

If it's still happening, a simple printer reset might do the trick

1. Turn off the printer.
2. Unplug the power cord from the back of the printer.
3. Press and hold the power button for 30 seconds.
4. Plug the power cord back in.
5. Turn on the printer. 

Also, checking for a firmware update from HP’s website could help if it's a software issue. You may refer to this guide on how to update the printer firmware: Update the firmware on an HP printer | HP® Support

Hopefully, this helps get your printer running smoothly again! 🤞
