2.2.2 LASER EXPOSURE
Overview
This machine uses a laser diode to produce electrostatic images on an OPC drum.
The laser diode unit converts image data from the FCU into laser pulses, and the
optical components direct these pulses to the drum.
Exposure of the drum by the laser beam creates the latent image. The laser beam
makes the main scan while drum rotation controls the sub scan.
