- About Solenoid
The solenoid in the printer opens or closes the shutter, or controls the position of the gear for transfer-
ring the torque of the motor to the roller.
By the passage of electric current through the coil inside the case, the solenoid becomes an electro-
magnet and attracts the plunger.
Upon the loss of power to the coil, electromagnetic force is lost, and the plunger returns to its original
position by spring action, thereby allowing the shutter to operate or the gear to move to the predefined
position.
Unlike a clutch, a solenoid generates a loud operation noise.
