Laser Exposure Process

The Start key is pressed.
The laser is forced ON.
The laser beam is corrected and the laser output is adjusted to an optimum level.
When the laser beam strikes the SOS Sensor, an SOS signal is generated.
The SOS signal, together with the HSYNC signal (the image start position in the CD
direction) and TOD signal (the image start position in the FD direction), determines the
laser emission timing.
A laser light is emitted in accordance with the VIDEO signal (image data).
The laser light strikes the surface of the PC Drum to form an electrostatic latent image.
