Laser Exposure System
Overview
Laser exposure system forms the electrostatic latent image on the photosensitive drum by the
laser exposure.
This system is composed of the laser assembly and the scanner motor assembly that are
unified as the laser scanner unit.
This machine uses the 2-beam method that enables the exposure of 2 beams per scanning,
and uses the 1-polygon 4-laser method in order to achieve a compact size.
