Chapter 2 Operation of Diagnostic
- About Clutch
The electromagnetic clutch in the printer controls the rotation of the roller by allowing or interrupting the
torque transmission from the motor to the roller.
By the passage of electric current through the coil inside the case, the electromagnetic clutch becomes
an electromagnet, 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 operation
of the component.
