| JAM type | External LCT transport section (When LU-205 or LU-303 is installed) | |
| JAM code | 17-20 | |
| JAM detection timing | The tray 2 vertical transport sensor (PS12) is not turned ON even after the set period of time has elapsed after the LU paper feed sensor (PS3) turns ON by a paper. | |
| – | 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 | Lower right 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) |
