Paper Jam - but no paper and no jam

HP Recommended
Color Laserjet Pro MFP M476dw
macOS 10.15 Catalina

Hi... my printer has started giving a Paper Jam error message after practically every print... tells me I need to open the back door and clear the jam - there is no jam... open the door, close it and the printer restarts - and will then print... once more.

 

It's clearly a faulty sensor, but I don't know where to start looming - any ideas?

When you print do you hear the pickup mechanism rotate more than once? If so, then based on the age of the machine it might be that the pickup roller is worn or dirty. The pickup roller should be a uniform color and have finger print ridges on it. Check you tube for videos on how to remove the pickup roller. If badly work will need to be replaced, dirty ones can be cleaned with a water dampened soft cloth.

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.

Thanks for the reply... I've listened to the machine and the pick up sounds to be working without additional noise - probably worth cleaning the roller anyway as the machine is a few years old!

 

But where there does seem to be additional noise is once the print is complete. The paper has been spat out, but these rollers seem to continue rolling for a while longer... and I'm getting the error with pretty much every single print job now....

Does that shed any further light on the issue?
