| JAM type | Misfeed at tray 3/4 horizontal transport section | |
| JAM code | 17-30, 17-31 | |
| JAM detection timing | 17-30 | The horizontal transport sensor (PS29) 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 tray 3 paper feed sensor (PS21). |
| 17-31 | The LCC vertical transport sensor (PS28) 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 horizontal transport sensor (PS29). | |
| – | Paper jam of a sheet of paper left at the tray 3/4 horizontal transport section results, if the horizontal transport sensor (PS29) is turned ON 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 tray 3/4 horizontal 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. | |
| Misfeed processing location | -Tray 4 -Tray 3/4 horizontal transport unit -Right bottom door | |
