5. Make adjustments so that the gray area on each color sample of the output test pattern becomes parallel to the main scan direction.
Calculate the correction values for cyan, magenta, and yellow in the following way.
1. Check the numbers indicated on the ends of A and B which correspond to the darkest black lines in the gray area of each color
pattern. (In the example of the yellow pattern, "1" is selected for the end of A and "7" is selected for the end of B.)
