| JAM type | Tray 3/4 horizontal transport section | |
| JAM code | 17-31 | |
| Detection timing | The LCC vertical transport sensor (PS28) is not unblocked even after the lapse of a given period of time after the paper has blocked the horizontal transport sensor (PS29). | |
| – | The horizontal transport sensor (PS29) is blocked when the main power switch is turned ON, a door or cover is opened and closed, or a misfeed or malfunction is reset. | |
| Misfeed processing location | Tray 3/4 horizontal transport unit | |
