panel. The variable needed to recalculate the luminosity of the toners is determined in a
slightly different way—you identify the black dot that best matches a 30% dot gain
field. When all values have been entered, the printer’s toner density and luminosity
settings are recalculated.
Gray Balance
The second VisualCal page, “Gray Balance,” provides the basis for calculating a
“neutral gray balance,” that is, a CMY gray that as closely as possible matches a pure K
(blacK) gray produced by the printer’s engine. This page consists of rows of CMY gray
patches on a field of gray produced solely from black.The variables needed to calculate
the printer’s most neutral gray balance are determined by identifying the CMY patch
that best matches this field, and entering its row and column location on the control
panel. When the values have been entered, the printer’s gray balance is recalculated.

:
Zero (0) and 9 are unacceptable values for color calibration. If you select 0 for
any of the colors, the resulting calibration will be inaccurate. If the entered value for
any color is 9, the Limits and 30% Match page is reprinted automatically. Re-enter
values for all color rows starting with Black Start.
When you have finished entering all values, the
