hp laserjet pro 400 color m451dn keeps saying "Jam in Tray 1" I have looked and there is no paper in the printer. I pulled tray 2 out and looked under the tray 1 plate and also pulled the back cover off and there is no paper in that location either.
I replaced the the rollers that sit behind tray two as that is what a lot of people are saying fixed their issue. I cleaned out everything i could in the printer and even with ZERO paper in tray 1 it still kicks out "Jam in Tray 1"
Anyone able to help me out here?
thanks

I have worked on a couple of the MFP versions of this device and have found that the optical sensor in the paper path near the rollers fails and causes this unclear able error.
