The motor (staple unit) controls the stapling. The paper stack is positioned under the staple arm, which clamps the
stack to hold it in place during stapling. If the number of sheets in the stack exceeds the limit, then the stack is fed to
the bin without being stapled.
Staple finisher bin section
The bin height depends on the amount of paper on the bin. The motor (staple finisher elevator) controls the bin
movement.
