3. Using the produced test pattern, adjust so that the gray line on each color pattern extends in parallel with the main scanning direction.
Follow the steps given below to calculate the setting value of each of cyan, magenta, and yellow:
1. On the ends on side A and side B on each color pattern, identify the numeral at which the darkest gray line is located. (For the sample
yellow pattern, the numerals are "1" on side A and "7" on side B.)
2. The setting value is the numeral on side B subtracted from the numeral on side A. (For the sample yellow pattern, 1 - 7 = 6 and the
setting value is "-6".)
4. Touch the key of the color to be adjusted.
5. Enter the setting value calculated in step 4 and touch [END].
