(3) Laser scanner unit
The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser
beam is dispersed as the polygon motor (PM) revolves to reflect the laser beam over the drum. Various lenses
and mirror are housed in the laser scanner unit, adjust the diameter of the laser beam, and focalize it at the
drum surface.
