Laser Exposure Process
1. The Start key is pressed.
2. The laser diode is forced to turn ON and the laser intensity is automatically adjusted.
3. The SOS Sensor Board is illuminated by the laser beam, which generates an SOS sig-
nal.
4. The SOS signal determines the laser emission timing for each main scanning line.
5. The surface of the PC Drum is illuminated by the laser beam corresponding to the
image data, which forms an electrostatic latent image.
