Laser scanner system
The laser scanner system forms latent images on the photosensitive drums according to the VIDEO
signals sent from the formatter.
The main components of the laser/scanner are the laser unit and the scanner motor unit. The DC
controller sends signals to the laser/scanner to control the functions of these components.
