| JAM type | Tray 3/4 intermediate transport roller section | |
| JAM code | 17-40, 17-41 | |
| JAM detection timing | 17-40: 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 tray 4 paper feed sensor (PS162). | |
| 17-41: The tray 2 vertical transport sensor (PS19) 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 vertical transport sensor (PS153). | ||
| Paper jam of a sheet of paper left at the tray 3/4 intermediate transport roller section results, if the tray vertical transport sensor (PS153) 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 intermediate transport roller 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 | -Right door -Tray 3/4 horizontal transport unit | |
| Relevant parts | -Intermediate motor (M151) -Transport motor (M152) -Tray 2 vertical transport motor (M23) -Tray 4 paper feed clutch (CL161) -Vertical transport sensor (PS153) -Tray 4 paper feed sensor (PS162) -Tray 2 vertical transport sensor (PS19) -PC control board (PCCB) -Base board (BASEB) |
