| JAM type | Duplex transport section | |
| JAM code | 93-10 | |
| Detection timing | A sheet of paper does not unblock the ADU paper passage sensor/2 (PS48) after a predetermined period of time has elapsed since the sheet blocks the ADU paper passage sensor/1 (PS47). | |
| – | The ADU paper passage sensor/1 (PS47) is blocked, or ADU paper passage sensor/2 (PS48) is unblocked when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset. | |
| – | The ADU paper passage sensor/1 (PS47) or ADU paper passage sensor/2 (PS48) is blocked when the main power switch is turned ON. | |
| Misfeed processing location | Duplex door | |
