| JAM type | Misfeed at external LCT transport section (When LU-205 or LU-303 is installed) | |
| JAM code | 17-20 | |
| JAM detection timing | 17-20: The tray 2 vertical transport sensor (PS19) is not turned ON even after the lapse of a given period of time after the paper has turned ON the paper feed sensor (PS3). | |
| Paper jam of a sheet of paper left at the external LCT transport section results, if the LU paper feed sensor (PS3) is turned ON 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 bottom door | |
| Relevant parts | -LU transport motor (M3) -Tray 2 vertical transport motor (M23) -LU paper feed sensor (PS3) -Tray 2 vertical transport sensor (PS19) -LU drive board (LUDB) -Base board (BASEB) |
