| JAM type | Misfeed at duplex transport section | |
| JAM code | 93-10 | |
| JAM detection timing | 93-10 | The ADU paper passage sensor/2 (PS48) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the ADU paper passage sensor/1 (PS47). |
| – | Paper jam of a sheet of paper left at the duplex transport section results, if the ADU paper passage sensor/1 (PS47) is turned ON, or the ADU paper passage sensor/2 (PS48) is turned ON (blocked) when the main power switch ON 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 the main power switch is turned ON, the ADU paper passage sensor/1 (PS47) is turned ON. | |
| – | Paper jam of a sheet of paper left at the duplex transport section results, if the main power switch is turned ON, the ADU paper passage sensor/2 (PS48) is turned ON. | |
| – | 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. | |
