Density And Color Balance Test Pattern - Xerox DocuPrint C55 Service Manual

Density and Color Balance Test Pattern.

This test pattern is used to set the density and to
determine if the printer color is balanced properly. It will
allow the customer to judge the color balance, and
correct the color balance if necessary. Refer to ADJ. 3.1
Density and Color Balance Procedure in Section 4 for
additional information.
NOTE: It is often difficult to see changes in the color
balance. You can check the change by running a printer
diagnostic sheet before and after the adjustment.
Changes will show in the values under Density Rate
Setpoints and Developer Bias. The NC60 includes
these values on the Density and Color Balance Test
Pattern.
On the NC60 only, you must disconnect all input ports
from the ESS before performing this adjustment.
