(1) Laser scanner unit

The charged surface of the drum is then scanned by the laser beam from the laser scanner unit.
The laser beam (780 nm wavelength) 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.
