| JAM type | Tray 3/4 intermediate transport roller section | |
| JAM code | 17-40 | |
| JAM detection timing | The LCC vertical transport sensor (PS28) is not turned ON even after the set period of time has elapsed after the tray 4 paper feed sensor (PS26) turns ON (unblock) by a paper. | |
| – | Paper jam of a sheet of paper left at the tray 3/4 intermediate transport roller section results, if the LCC vertical transport sensor (PS28) 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 -Tray 3/4 horizontal transport unit | |
| Relevant parts | -LCC transport motor (M25) -LCC vertical transport motor (M26) -Tray 2 vertical transport motor (M7) -Tay4 paper feed clutch (CL7) -Tray 2 vertical transport sensor (PS12) -Tray 4 paper feed sensor (PS26) -LCC vertical transport sensor (PS28) -Paper feed/transport drive board (PFTDB) -MFP board (MFPB) |
