This printer has a permanent "Jam in output bin. Open rear door and clear jam" error that will not go away. There is no jam and there never was. When the error first started you could open and close the rear access and it would go away until after the next print job. However, over time this worked less and less until now it doesn't work at all.
I've tried all of the standard steps posted by HP staff about resetting it, checking paper tray, powering off and on etc so it is clearly either a damaged sensor or something blocked one of them. Upon looking very closely at the rear access area I cannot see any visible damage or dirt.
I've seen a couple of posts including this one referencing the sensor flags, but I'm not sure if I can find them. This is the closest thing I can find to the description in the linked post. This paper guide has one of these white bits on either end that moves up and down, and the left one does pop out very slightly when pressed in. However, when the printer is closed up these aren't pushed down so I can't see it being that.
Is anyone able to advise what the issue might be? I'm at a complete loss.
