1. The laser light of each color enters the cylindrical lens via the synthetic mirror and return mirror (light source).
2. At the cylindrical lens, each laser light is condensed in the vicinity of the polygon mirror.
3. Since the angle of incidence for each color of laser light varies, the laser light reflected by the polygon mirror is reflected in a different
angle for each color.
4. The condensing angle of each color of laser light is corrected by the G1 lens and then reaches each return mirror.
5. The K laser light is condensed on the photo conductor surface via the G2 lens and return mirror1. The Y laser light is condensed on the
photo conductor surface via the return mirror1, G2 lens, and return mirror2. The M laser light is condensed on the photo conductor
surface via the return mirror1, G2 lens, and return mirror2. The C laser light is condensed on the photo conductor surface via the return
mirror1, G2 lens, return mirror2, and return mirror3.
