Tone Curve Adjustment
Makes the grayscale of the printed image more consistent with the original. Perform calibration before using tone
curve adjustment. If you find that the grayscale is not improved by Calibration (see page 9-71), use tone curve
adjustment.
NOTE: To perform tone curve adjustment, verify that either Letter or A4 paper is loaded into a cassette.
A total of 2 pattern pages (No. 1 and 2) are printed during adjustment. The printed patterns are read sequentially
during the adjustment.
