| JAM type | Misfeed at duplex transport section | |
| JAM code | 93-10 | |
| JAM detection timing | 93-10: The ADU paper passage sensor/2 (PS41) is not turned ON (blocked) even after the lapse of a given period of time after the leading edge of the paper has turned ON (unblocked) the ADU paper passage sensor/1 (PS40). | |
| Paper jam of a sheet of paper left at the duplex transport section results, if the ADU paper passage sensor/1 (PS40) is turned ON (unblocked) or the ADU paper passage sensor/2 (PS41) is turned ON (blocked) 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. | ||
