Calibrating from the Control Panel using VisualCal
VisualCal is a calibration method that allows you to calibrate your printer to a color 
output standard defined by the manufacturer. The calibration calculations performed 
by the controller software are based on a series of values entered on the Control Panel. 
The values used in the calculations are determined by evaluating toner densities and 
color combinations produced on two specially designed calibration pages printed from 
the Control Panel.
Limits and 30% Match
The first VisualCal page, “Limits and 30% Match,” provides the basis for calculating 
the most acceptable luminosity (brightness) of the toners. This page consists of rows of 
CMYK dots in a graduated range of toner densities.
The variables needed to recalculate the density of the colored toners are determined by 
identifying the leftmost dots that can be fully distinguished against their fields in each 
row, and sequentially entering their corresponding numeric values on the Control 
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.
