Troubleshooting. Jam Codes: 10-01, 10-02, 10-04, 10-40
Contents
| JAM type | Misfeed at manual bypass paper feed section |
| JAM detection timing | 10-01 The leading edge of the paper is not turned ON (unblocked) the registration sensor/1 (PS1) even after the lapse of a given period of time after the manual bypass tray starts to feed paper. |
| 10-02 For paper fed from the manual bypass tray, 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. |
|
| 10-04 The leading edge of the paper is not turned ON the registration sensor/2 (PS72) even after the lapse of a given period of time after the manual bypass tray starts to feed paper. |
|
| 10-40 For paper fed from the manual bypass tray, 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. |
