Summary of Each Adjustment

Sub scan line position for YCM
The adjustment of the sub-scan line position for YCM uses the line position for K as
a reference (color registration). The machine measures the gaps between the lines
of each color in the pattern on the transfer belt. If the gaps for a color are not
correct, the machine moves the image of the color up or down the sub scan axis.
To do this, it changes the laser write timing for that color.
Main scan line position for KYCM
If the machine detects that the image is out of position in the main scan direction, it
changes the laser-write-start timing for each scan line.
Magnification adjustment for KYCM
If the machine detects that magnification adjustment is necessary, it changes the
LD clock frequency for the necessary color.
Skew for YCM
The adjustment of the skew for YCM uses the line position for K as a reference.
