Default Setting (System Menu) 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).
