(7-2) Laser scanner unit
The charged drum surface is scanned by the laser emitted from the laser scanner units. The laser reflects to
the polygon mirrors by rotating the polygon motor so that the laser scans horizontally to the image. The laser
scanner unit has some lenses and mirrors, that adjust the diameter of the laser to focus the laser to the drum
surface.
