| JAM type | Misfeed at duplex transport section | |
| JAM code | 93-10 | |
| Detection timing | The ADU paper passage sensor/2 (PS41) is not blocked even after the set period of time has elapsed after the ADU paper passage sensor/1 (PS40) is unblocked by the paper. | |
| – | In case the ADU paper passage sensor/1 (PS40) is unblocked or the ADU paper passage sensor/2 (PS41) is blocked after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at duplex transport section. | |
| – | In case the registration sensor (PS1) is unblocked after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at duplex transport section. | |
| – | In case paper position is detected as locating properly after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at duplex transport section. | |
| Misfeed processing location | Duplex door | |
