2.4.8.2 Laser Emission Timing (SOS Signal)
•
The signal output from the Master Board triggers the firing of the laser. The laser beam travels to the
Polygon Mirror, lens, and SOS Mirror to eventually hit the SOS Sensor, which generates an SOS signal.
•
The SOS signal determines the laser emission timing for each line in the main scanning direction.
