The staple hammer [A] is driven by the staple motor [B] via gears [C], two
eccentric cams [D], and two links [E].
When the aligned copies are brought to the staple position by the positioning
roller, alignment brush roller and jogger fences, the stapler motor starts
rotating. When the cams complete one rotation, the stapler home position
sensor [F] turns on detecting the end of the staple operation. The stapler
motor then stops.
There is a reflecting photosensor [G] in the staple unit to detect staple end
conditions.
