Adjustments and Maintenance Procedures

C C o o l l o o r r C C a a l l i i b b r r a a t t i i o o n n
Use Color Calibration to maintain consistent colors. You can adjust the color density, gray balance, or
both. For the best results, adjust the color density, then adjust the gray balance.
At the start of each color calibration procedure, three pages are printed.
1. An instruction sheet explaining the calibration and evaluation procedures that are used for both
color density calibration pages, and the gray balance calibration pages.
2. An initial Color Reference Page with color density patches, ranging from 5 percent to 100 percent.
Mark this initial page to identify it from the final Color Reference Page, which is printed
automatically at the completion of your adjustments. Comparing the initial print with the final
print allows you to compare visually the results of your adjustments.
3. A calibration page that changes, based on the adjustment procedure. The calibration page is your
primary tool for evaluating when an adjustment is required. To allow you to repeat an adjustment
until the calibration is complete, this page reprints each time you make an adjustment. All colors
on a calibration page reflect the previous adjustments. An adjustment is complete when the
center, or zero, position shows the best available color setting.

Adjusting color density allows you to calibrate the density and balance of the four primary colors of
cyan, magenta, yellow, and black. The density settings adjust the printed output, based on the level
of color saturation. If you select the minus settings, the color density decreases and the output light-
ens. If you select the plus settings, the color density increases and the output darkens. Examples of
low density areas include faces and sky.
Starting a Color Density Calibration
To begin your calibration and print the calibration pages:
1. At the printer control panel, press the Home button.
2. Log in as administrator. For details, refer to the System Administrator Guide at
support/VLC8000docs
3. Touch Device→Support→Color Calibration.
The third page printed at the start of your color density
adjustment is the Cyan/Magenta Calibration Page. This
page contains a range of density settings available for cy-
an and magenta. The current density setting for each of
the light, medium, and dark rows are numbered zero. The
available settings are printed in a comb pattern, against
a background representing the desired density setting. If
the best match is between two combs, select a value be-
tween the two printed combs.
