Laser exposure process
A. Operation
1.
The K laser light enters the cylindrical lens via the return mirror (light source). The
Y, M, and C laser light enter 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 and G2
lenses and then reaches each return mirror.
5.
The K laser light is condensed on the PC drum surface via the G3 lens and return
mirror /1. The Y and M laser light is condensed on the PC drum surface via the
return mirror /1, G3 lens, and return mirror /2. The C laser light is condensed on the
PC drum surface via the return mirror /1, return mirror /2, G3 lens, and return mirror
/3.
