| JAM type | Misfeed at tray 1 paper feed section | |
| JAM code | 11-01, 11-02, 11-04, 11-05, 11-40 | |
| JAM detection timing | 11-01: After the tray 1 starts to feed paper, the registration sensor/1 (PS1) is not turned ON (unblocked) 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 (PS23). | |
| 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. | ||
| 11-04: The leading edge of the paper is not turned ON (unblocked) the registration sensor/2 (PS72) even after the lapse of a given period of time after the tray 1 starts to feed paper. | ||
| 11-05: The leading edge of the paper is not turned ON the tray 1 paper feed sensor (PS23) 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 paper feed sensor (PS23) is turned ON when operation stops due to the tray 1 FD size error. | ||
| Misfeed processing location | -Right door -Tray 1 | |
| Relevant parts | -Paper feed motor (M22) -Registration motor (M24) -Registration sensor/1 (PS1) -Tray 1 paper feed sensor (PS23) -Registration sensor/2 (PS72) -Base board (BASEB) |
