Weird issue on Bizhub 751

[Downunder]

Above tray two you have the little transport tray. There are two sensors above that tray. Best to look from the right hand side of machine when covers removed. Might be worth checking to make sure everything is good with the sensors. Vaguely remember this caused a similar issue many years ago.

Everyone covered anything I can think of. Random idea: Try changing the paper size detect in Tech Rep Mode
