[A]
The staple hammer motor [A] drives the staple hammer.
The staple sheet sensor [B] detects the leading edge of the staple sheet at the
stapling position to prevent the hammer from operating if there are no staples at
the stapling position.
If there is no staple cartridge in the stapler unit or no staples in the staple cartridge,
staple end is indicated on the operation panel. The stapler sensor [C] detects this.
The stapler rotation HP sensor [D] checks whether the staple hammer mechanism
returns to home position after each stack has been stapled.
When excessive load is applied to the staple hammer motor, the copier detects a
staple jam. When a staple jam has occurred, the jammed staple is inside the staple
cartridge [E]. Therefore, the jammed staple can be removed easily after pulling out
the staple cartridge.
