Coarse and Fine Skew Adjustments
Skew error is the misalignment of one or more of the four scan lines (C, M, Y, K). During the
RegiCon #4 (Coarse) and RegiCon #1 (Fine) adjustments, the front side of each line is
adjusted to be level with the rear end.

In/Out Skew Adjustment
The In/Out Adjustment (Magnification) ensures that all four scan lines are the same length.
During RegiCon #2, the printer measures, then adjusts the four scan lines to the proper length.
Figure 3 Magnification
Center Skew Adjustment
The Center Skew Adjustment (Magnification Balance) adjusts the linearity of the scan lines.
During RegiCon #3, the printer measures a specific midpoint of each scan line and adjusts it to
a horizontal reference midpoint.
