| JAM type | Misfeed at tray 1 feed section | |
| JAM code | 11-40 | |
| JAM detection timing | For paper fed from the tray 1, the image write start signal permit continues to be disabled for a predetermined period of time after the timing of the image write start signal output. | |
| – | Paper jam of a sheet of paper left at the tray 1 feed section results, if the tray 1 vertical transport sensor (PS4) 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 1 feed section results, if the tray 1 vertical transport sensor (PS4) is turned from OFF to ON while the tray 1 paper feed sensor (PS5) is OFF. | |
| Misfeed processing location | Manual bypass tray door | |
| Relevant parts | -Paper feed motor (M22) -Tray 1 vertical transport motor (M5) -Tray 1 paper feed clutch (CL1) -Tray 1 vertical transport sensor (PS4) -Tray 1 paper feed sensor (PS5) -Paper feed/transport drive board (PFTDB) -MFP board (MFPB) |
