Paper jams are detected by the registration sensor [D] and the exit sensor [E]. Jam
detection timing is determined by the drum position sensors and the main motor
encoder (not shown). The 2nd feed timing sensor [A] and the paper exit timing
sensor [B] are used as the drum position sensors.
The timing chart on the next page shows the jam detection timing.
