1.3.2 Exposure

The exposure process forms an invisible electrostatic latent image on the negatively charged drum sur-

face by scanning it with laser beams.

This process is performed in parallel for yellow, magenta, cyan and black colors.

Laser beams are emitted from the laser diode in the ROS ASSY. The surface of each color drum is

scanned from end to end in the axial direction by the rotating polygon mirror, the fixed mirror, and

the lens attached to the Scanner Motor Assy of the ROS ASSY.
