CHAPTER 5  LASER EXPOSURE SYSTEM

III.  LASER DRIVER PCB

A.  Outline

Figure 5-300 shows the laser driver PCB, which drives the laser semiconductor using control

signals and the image signals from the image processor PCB. The circuit has the following
functions:

1.

Driving the laser semiconductor

2.

Stabilizing the laser intensity (APC control)

3.

Switching laser activation mode

4.

Switching laser output

The image signals from the image processor are written in the line memory in conjunction with

the sync signals generated for internal use on the laser driver PCB. The laser drive signals are
generated based on these image signals to drive the laser semiconductor.
