Operation

8.2.1

Overview

• Four semiconductor lasers provided, one for each of the four different colors. A single
polygon motor is used to make a scan motion.
• Each photo conductor is irradiated with a laser light so that an electrostatic latent image
is formed on it.
8.2.2

Laser exposure process

1. The laser light emitted by each of the semiconductor laser/Y, M, C, and K is
reflected onto the polygon mirror via the synthetic mirror.
2. Since the angle of incidence for each color of laser light varies, the laser light
reflected by the polygon mirror is reflected at a different angle for each color.
3. The condensing angle of each color of laser light is corrected by the G1 lens before
reaching each return mirror.
4. The laser light of each color is condensed on the surface of the photo conductor
through the return mirror/1st, G2 lens, and return mirror/2nd.
