Troubleshooting. Jam 06. Misfeed at duplex pre-registration section
Detection timing
Type | Description |
---|---|
Detection of misfeed at duplex pre-registration section | • The leading edge of the paper does not turn ON the sensor in front of tim. roller (PS23) even after the lapse of a given period of time after a duplex paper feed sequence has been started. |
Duplex pre-registration section loop registration reversing jam detection | • For the second-side feed of paper in the duplex mode, loop forming has not been complete before the second side of a sheet enters the timing roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop. |
Duplex pre-registration section TOD permit waiting jam | • For the second-side feed of paper in the duplex mode, TOD permit continues to be disabled for a predetermined period of time after the timing of TOD output. |
