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 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.
