Theory of Operation
Laser Unit
The Laser Unit generates laser beams to form an electrostatic latent image on the
drum surface. The Laser Unit consists of a laser diode (LD) board, scanner, start of
scan (SOS) board, lenses, mirrors, and windows.
• Laser Diode Board
The laser diode board consists of four laser diodes (LDs) corresponding to C,
M, Y, and K. Each LD converts the electric signals of incoming image data into
laser beams. In order to stabilize the laser light quantity during formation of
an electrostatic latent image, the laser diode board monitors the intensity of
the laser beam to adjust it to the appropriate level. This process is called auto
power control (APC).
