Laser/scanner system
The laser/scanner system forms the latent electrostatic image on the photosensitive drums according to
the VIDEO signals sent from the formatter. The product has two laser/scanners: one for yellow and
magenta and the other for cyan and black.
The formatter sends the DC controller instructions for the image of the page to be printed. The DC
controller signals the lasers to emit light, and the laser beams pass through lenses and onto the scanner
mirror, which rotates at a constant speed. The mirror reflects the beam onto the photosensitive drum in
the pattern necessary for the image, exposing the surface of the drum so it can receive toner.
