5.1 Construction

5.1.1 Overview

0020-4075

The laser scanner unit consists of a laser driver, scanner motor, and others. It is controlled by the signals from the DC controller PCB.

The laser driver operates the laser diode to emit light in response to the laser control signals and video signals from the DC controller PCB.

Laser beams are emitted, through a collimator lens and cylindrical lens, to the hexahedral mirror rotating at a constant speed.

Laser beam reflected by the hexahedral mirror focus on the photoconductor drum via the imaging lens and loop-back mirrors installed before the hexahedral mirror. 

When the hexahedral mirror rotates at a constant speed, the photoconductor drum is scanned with laser beams at a constant speed. 

When the photoconductor drum rotates at a constant speed and the photoconductor is scanned with laser beams at a constant speed, a latent image is formed on the

photoconductor drum.
