Color Calibration
The color calibration procedure is used to ensure consistent color reproduction over time for copies and
prints. Performing the calibration procedure adjusts the output densities to be as close to the printer’s
specified values as possible. If performed on media which has lower densities the outcome will be
increased densities and vice versa. It should be performed if optimal color reproduction and
consistency over time is desired.
1. Press the Log In/Out button on the control panel.

Note:
To fully calibrate both copies and prints it is necessary to run all four job types and apply them to
the corresponding type. If such precision is not needed one should select the most important output
type and then apply the results to both copy and print jobs. If one is experiencing color reproduction
issues in one Job type but not the others then it is only necessary to run calibration for the problematic
job type.
