| 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 (PS12) 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 paper 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 (M7) -LU paper feed sensor (PS3) -Tray 2 vertical transport sensor (PS12) -LU drive board (LUDB) -Paper feed/transport drive board (PFTDB) -Base board (BASEB) | |
