"Angle stapling at 1 front corner", "Angle stapling at 1 rear corner" and "Double stapling (side
stitching)"
1) 1) through 7) are the same operation as the offset operation.
8) Gripper conveys the paper stack to the stapling position with holding the stack.
"The operation 9) and 10) are applicable only to the front/ rear corner stapling."
9) After stapling the paper stack, the gripper starts to eject the stack on the stack tray.
10) At the same time, the stacking height detection lever moves up.
The detection lever moves down when the paper stack has ejected on the stack tray to
detect the paper.
"The operation 9)' through 18) are applicable only to the double stapling (side stitching)."
9)The shift roller moves down and gives higher pressure to the paper stack. Gripper then
opens and evacuates itself to the connecting position with the stapler.
