Tone Curve Adjustment

After prolonged use, or from the effects of surrounding temperature or humidity, the hue of printed color output
may shift or color drift may occur. Use this function to correct color settings when the color of a finished copy
does not match the original. Perform calibration before using tone curve adjustment. Use tone curve adjustment
when the color is not enhanced even after performing calibration (see page 9-73).
NOTE:
To perform tone curve adjustment, verify that either Letter or A4 paper is loaded into a cassette.
A total of 3 pattern pages (No. 1 to 3) are printed during adjustment. The printed patterns are read sequentially
