| JAM type | Misfeed at tray 2 feed section | |
| JAM code | 12-01 | |
| JAM detection timing | The leading edge of the paper is not turned ON the tray 2 vertical transport sensor (PS12) even after the lapse of a given period of time after the tray 2 starts to feed paper. | |
| – | Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | |
| – | When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned from OFF to ON. | |
| Misfeed processing location | Lower right door | |
| Relevant parts | -Paper feed motor (M22) -Tray 2 vertical transport motor (M7) -Tray 2 paper feed clutch (CL2) -Tray 2 vertical transport sensor (PS12) -Tray 2 paper feed sensor (PS13) -Paper feed/transport drive board (PFTDB) -MFP board (MFPB) |
