at the specified time. The puncher will move down to make the punch hole at the back
edge of the paper. (The punch hole will be made sheet by sheet.)
• The drive cam will be rotated by the punch motor inside the punch unit to move the slide
cam back and forth. The slide cam will move the puncher down to make the punch holes.
