JAM type | Misfeed at duplex pre-registration section | |
JAM code | 92-01, 92-02, 92-04, 92-40 | |
JAM detection timing | 92-01: 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 a duplex paper feed sequence has been started. | |
92-02: 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 registration roller because the rise timing of load to perform registration is earlier than the rise timing of load to form a loop. | ||
92-04: The registration sensor/2 (PS72) is not turned ON even after the lapse of a given period of time after a duplex paper feed sequence has been started. | ||
92-40: For the second-side feed of paper in the duplex mode, 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 duplex pre-registration section results, if a sheet of paper is determined to exist at a position detected when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | ||
