Operation:

1.Determine which patch composed of CMY toners have the most neutral gray that close to the background gray

composed of K toner.

2.Enter the value of row and column in front panel.

3.If the number of row is not 0, the Gray balance page is printed again. Repeat from 1.

4.When the current gray balance that is printed at row 0 matches most the background, gray balance is achieved.

Select 0 and continues.

Apply changes

Before applying the calibration changes compare the Color Test that uses the original calibration values against the

Color Test that uses the new values. If you are satisfied with the printer’s calibration based on the new values, select

Yes from the Apply Changes screen that appears, and press the Enter button to recalibrate the printer based on the

previously entered values. If you are not satisfied with the printer’s calibration based on the new values, select No

from the Apply Changes screen that appears. Or if you want to reset the calibration, select Default.

Effect

Because the density level or color balance does not shift much in normal usage, the effect of VisualCal may not be

obvious in most cases. But if you feel the print quality has really deteriorated in a certain condition, this tool must

help improve the quality.
