Theory of Operation
Exposure
Four laser diodes (one for each color) in the Laser Unit emit laser beams. The
beams are directed by mirrors to the rotating polygon mirror attached to the
scanner motor. As the polygon mirror rotates, the beams are directed through a
series of lenses and mirrors to each of the drums, which are scanned by the beams
from end to end in the axial direction.
The negatively charged drum surface is scanned by the laser beams to form an
invisible electrostatic latent image on the drum surface. The process is performed
in parallel for all colors. The area on the drum where the laser beam strikes
becomes conductive. The negative charge on the surface flows to the more
positive drum, lowering the voltage potential.
