[E]
In staple mode, when stapling is completed, the exit unit lift motor [A] starts
rotating to open the exit unit [B]. This is to prevent paper jams when a thick
paper stack is exiting. The exit unit lift motor stops when the exit unit half turn
sensor [C] is actuated. While the paper stack is exiting, the exit unit lift motor
starts rotation again to close the exit unit. The upper and lower exit rollers [D]
catch the stack of copies to feed them out. The exit unit lift motor stops when
the exit guide home position sensor [D] is actuated.
The exit unit lift motor does not work in sort/stack mode.
The exit drive motor starts rotating to drive the exit rollers [E] when the first
copy activates the entrance sensor. The exit drive motor speed is reduced
just before each copy paper is completely fed out. This is to ensure an even
copy stack.
