JAM type	Misfeed at duplex transport section
JAM code	93-03
JAM detection timing	93-03: The leading edge of the paper is not turned ON (unblocked) the ADU transport sensor (PS11) even after the lapse of a given period of time after the paper has turned OFF (blocked) the paper exit sensor (PS13).
	– Paper jam of a sheet of paper left at the duplex transport section results, if the ADU transport sensor (PS11) is turned ON (unblocked) when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset.
	– Paper jam of a sheet of paper left at the duplex transport section results, if a sheet of paper is determined to exist at a position detected when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset.
Misfeed processing location	Right door
