(1) Image Drum Unit
The image drum unit consists of a light-sensitive drum, a charger, and a developer. The unit forms a toner
image on the sensitive drum, using an electrostatic latent image formed by the LED head.
(2) Registration Motor
The registration motor is a pulse motor of 48 steps/rotation, which is two-phase excited by the signal from
the Main Control PCB. It drives the hopping and registration rollers via two one-way clutches according to
the direction of rotation.
