| 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) |
Procedure

| 2 | PS3 I/O check, sensor check | LUDB CN5-8 (ON) | LU-205/LU-303 4-G |
| 3 | PS12 I/O check, sensor check | PFTDB CN12-10 (ON) | 3-P |
| 4 | M3 load check -Check code: 28 -Multi code: 21, 22, 23, 24 | LUDB CN4-1 to 4 | LU-205/LU-303 3-G |
| 5 | M7 load check -Check code: 28 -Multi code: 13, 14, 15, 16 | PFTDB CN10-9 to 12 | 13-P |
| 6 | Replace LUDB. (LU-205 Part# A8H6H00100 /LU-303 Part# A8H6H00100) | – | – |
| 7 | PFTDB F1 or F4 conduction check | – | – |
| 8 | Replace PFTDB. (Part# A795H00200) | – | – |
