| JAM type | Tray 3/4 horizontal transport section | |
| JAM code | 17-31 | |
| JAM detection timing | The LCC vertical transport sensor (PS28) is not turned ON even after the set period of time has elapsed after the horizontal transport sensor (PS29) turns ON (block) by a paper. | |
| – | Paper jam of a sheet of paper left at the tray 3/4 horizontal transport section results, if the horizontal transport sensor (PS29) is turned ON (blocked) when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | |
| Misfeed processing location | Tray 3/4 horizontal transport unit | |
| Relevant parts | -LCC transport motor (M25) -Tray 3 transport clutch (CL6) -Horizontal transport clutch (CL3) -Tray 3 paper feed sensor (PS21) -Horizontal transport sensor (PS29) -LCC vertical transport sensor (PS28) -Paper feed/transport drive board (PFTDB) -MFP board (MFPB) |
