Duplex Stopper and Pick-up Roller Mechanism
The pick-up roller bracket is lifted up by the rearmost duplex stopper [A]. Both the duplex
stopper and the pick-up roller [B] are moved by solenoids.
When paper is being fed, the duplex stopper solenoid [C] is energized and the stoppers are
lowered. The pick-up roller bracket rotates downward and the pick-up roller drops onto the
copy paper. The duplex pick-up solenoid [D] is energized 160 milliseconds after the duplex
feed clutch turns on. Paper feed then begins. The pick-up roller stays in contact with the
paper during paper feed.
