2. Product Specifications and Description
2.7.2. Laser Scanning Optical path
The laser beam from the LSU is placed at intervals of 78mm for each color. All colors uses the same polygon motor for
oblique incidence.
F2 Lens [A] determines the slope of the primary scanning line and the image position of the secondary scanning direction.
This is adjusted at the factory. The primary scanning line slope by the machine difference is adjusted by skew adjustment
in the LSU.
Reflecting mirrors [B] on each color path adjust the curvature of primary scanning. This is adjusted at the factory.
