Exposing process
In the exposing process, the OPC belt surface is exposed to the
laser light which forms an electrostatic latent image.
The luminous source of the laser is a semiconductor laser. See
“Printer theory of operation” on page 1-19 for optical unit
location.
The laser light scans the OPC belt, forming an electrostatic latent
image.
1. The OPC belt surface is charged to -Vo(V) potential.
a. The laser scans the OPC belt in a rectangular pattern during
forward movement of the OPC belt.
b. High speed switching of the laser matches the transmitted
image data.
c. The charge of the areas radiated by the laser light is
discharged, creating a -VR(V) potential.
d. An electrostatic latent image is formed (invisible) on the
OPC belt.
