| JAM type | Tray 3/4 horizontal transport section | |
| JAM code | 17-30, 17-31 | |
| JAM detection timing | 17-30: The horizontal transport sensor (PS158) 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 (PS152). | |
| 17-31: The vertical transport sensor (PS153) 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 (PS158). | ||
| Paper jam of a sheet of paper left at the tray 3/4 horizontal transport section results, if the horizontal transport sensor (PS158) 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. | ||
