- About Clutch
The electromagnetic clutch in the printer controls the rotation of the roller by transferring or cut-
ting the torque from the motor to the roller.
The electromagnetic clutch becomes an electromagnet by the passage of electric current through
the coil inside the case and attracts the armature and gear to the rotating rotor, thereby rotating
the gear.
Upon the loss of power to the coil, electromagnetic force is lost and the armature comes off the
rotor, and the gear comes to rest.
The clutch makes so soft noises that you must be close the component to audibly confirm the oper-
ation of the component.
