(2) Optical section
The optical section consists of the laser scanner section to write the image.
(2-1) Laser scanner unit
The charged drum surface is scanned by the laser emitted from the laser scanner units. The laser reflects to the poly ­
gon 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. Also, the
LSU cleaning motor operates to automatically clean the LSU glass.
