2.Fine Skew Setup - Automatically performs horizontal and vertical alignment, and reports any skew in the 
various images caused by the printhead misalignment. The skew must be corrected through manual 
adjustment.
3.In/Out Setup - Automatically performs magnification adjustment so that scan lines are the same length for 
all four colors. Also checks for skew.
4.Center Setup - Aligns the midpoints of scan lines for all colors, for magnification balance. There is also a 
Rough Skew Setup when skew is outside the measurement parameters of the Fine Skew Test.
