Troubleshooting. Jam Code: 10-01, 10-02, 10-40
Contents
JAM type | Misfeed at manual bypass feed section |
JAM code | 10-01, 10-02, 10-40 |
Detection timing | 10-01 The leading edge of the paper does not unblocked the registration (PS1) even after the lapse of a given period of time after the manual bypass starts to feed paper. |
10-02 For paper fed from the manual bypass, 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. |
|
10-40 For paper fed from the manual bypass, 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. |
|
In case paper position is detected as locating properly after main power switch is turned ON, door and cover are opened / closed or jam/trouble reset is done, it is regarded as paper jam at manual bypass feed section. | |
