Stapling
The motor M3 rotates and operates a cam to move the stapler up and down. The
stapler detection cam makes a single rotation each time the stapler is activated.
The rotation of the cam is monitored by the sensor MS7.

Controlling the stapling motor M3
Motor M3 is a DC motor.
The stapling home position sensor (MS7) remains on while stapling operation
takes plate. (See figure 'Stapler Construction')
Stapling takes place when the motor M3 rotates clockwise. If a staple jam pre-
vents the motor from rotating clockwise, the motor is rotated in reverse, to re-
turn the stapler to the home position.
