constant error message says jam in back and back cover open. no paper in machine, back door is closed.

I've tried powering off and back on, but the error message comes up as soon as power is on.

Also tried a couple "reset" routines found no the web which did nothing.

I've removed the toner, paper cassette, duplex tray, opened the back door, flipped down two roller things in the back and am not seeing any paper, not even a tiny corner.

I have the parts manual for the printer, but I'm not seeing any sensors in the back that might be loose or covered by a bug.

Anyone have a clue?

I remember once where the exit sensor arm had fallen off. The sensor is a u shaped plastic near the center of the fuser.
