Laser Emission Timing - Xerox MF Series Technical Document

5-3.

Laser Emission Timing

• When a READY signal is detected a given period of time after the print command has
been issued, the Controller/Mechanical Control Board outputs a laser ON signal.
• The laser ON signal makes a laser beam to be emitted and the laser beam travels to the
Polygon Mirror, G1 Lens, and the 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.
