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
The laser light scans the OPC belt, forming an electrostatic latent image.
1.The OPC belt surface is charged to
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
d.An electrostatic latent image is formed (invisible) on the OPC belt.
