Color balance calibration page Step 2: Adjust the cyan (C) density setting. Examine the cyan density bar (C) on the color balance calibration page from a distance of 2 meters (6 ft). If the center oval matches the background pattern more than the other ovals, the cyan density does not need to be adjusted, and you should continue to the magenta (M) setting. If an oval left of center or right of center matches the background more than the center oval, use the following steps to enter the number: 1 2 Press [ITEM] until CYAN DENSITY appears. Press the right side of the [VALUE] key to increase the value, or press the left side to decrease it, until the number corresponding to the oval that most closely matches the background pattern appears. Press [SELECT] to save the value. An asterisk (*) appears next to the selected setting.

Step 3: Adjust the magenta (M) density setting. Examine the magenta density bar (M). If the center oval matches the background pattern more than the other ovals, the magenta density does not need to be adjusted and you should continue with the next step. If not, use the following steps to adjust the density: 1 2 Press [ITEM] until MAGENTA DENSITY appears. Press the right side of the [VALUE] key to increase the value, or press the left side to decrease it, until the number corresponding to the oval that most closely matches the background pattern appears. Press [SELECT] to save the value. An asterisk (*) appears next to the selected setting.
