Staple firing is driven by the corner stapler motor inside the stapler unit.
When the corner stapler motor is overloaded because of a staple jam, the machine displays an error on the operation panel and stops copying.
The self priming sensor and the cartridge set sensor are inside the stapler unit.
- The self priming sensor [A]: It detects whether the staple needle is at the staple position (upper position). If the sensor is OFF, it means that the staple needle is at the lower position. Therefore, the machine feeds the staple needle to the staple position.
- The cartridge set sensor [B]: It detects the cartridge at the correct position. It also detects the staple end condition. (If the sensor is OFF, the "Add Staple" icon is displayed on the operation panel)
If staple end is detected during copying, the "Add Staple" icon is displayed on the operation panel after the end of the job.
