The machine automatically adjusts the following items by drawing lines (1 mm x 20
mm) on the transfer belt and measuring them using the two ID sensors (one at the
front and one at the rear). The machine generates eight sets of these lines for each
color on both sides (front and rear) of the transfer belt, and averages the results
from measuring these sets.
1. Sub scan line position for YCM based on the line position for K (color
registration)
2. Main scan line position for KYCM
3. Magnification ratio for KYCM
4. Skew for YCM based on the line position for K
