[1] Printer Image
Processing
The intensity of the laser light is controlled by the image signal sent
from the image processor board.
[2] Laser Exposure The surface of the Photo Conductor is irradiated with the laser light
and an electrostatic latent image is thereby formed.
[3] Photo Conductor The image projected onto the surface of the Photo Conductor and is
converted to a corresponding electrostatic latent image.
[4] Photo Conductor Charging A negative Imaging Unit charge layer is formed on the surface of the
Photo Conductor.
