Laser scanner system, 10Laser/scanner system | HP Enterprise CP5525

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.
