During power-up process my 3620 says, "preparing"; runs the top feeder; feeds a sheet all the way through from the bottom tray and spits it out; then says fix paper jam, but if I put a sheet in the top/lid feeder it doesn't grab it even if I try to help it.
I also have a 3540, so I was going to swap tops. There is an extra 3-pin connector with gray and black wires in the 3620 lid harness. One wire was broken like it got caught in the gears. Appears to be no receptacle for it. 3540 doesn't have that connector and a simpler gear train so I didn't go through with the swap.
Where are the paper sensors located in this thing?
Are these symptoms an obvious telltale for the fix?
