| JAM type | Misfeed at tray 1 paper feed section | |
| JAM code | 11-01, 11-02, 11-05, 11-40 | |
| JAM detection timing | 11-01 | After the tray 1 starts to feed paper, the tray 1 vertical transport sensor (PS4) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the tray 1 paper feed sensor (PS5). |
| 11-02 | For paper fed from the tray 1, loop forming has not been complete before a sheet enters the registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop. | |
| 11-05 | The leading edge of the paper is not turned ON the tray 1 paper feed sensor (PS5) even after the lapse of a given period of time after the tray 1 starts to feed paper. | |
| 11-40 | 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 paper 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. | |
| – | Paper jam of a sheet of paper left at the tray 1 paper feed section results, if the main power switch is turned ON, the tray 1 vertical transport sensor (PS4) is turned ON while the tray 1 paper feed sensor (PS5) is ON. | |
| 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) -Base board (BASEB) | |
