About Controller Calibration

Calibration is essential to ensure that colors are accurately reproduced when using this machine, because
color reproducibility can change from day to day.
The following two calibration methods are available:
-
Color Density Control: Automatic adjustment and manual adjustment, by using a main body function
- Calibration: Manual adjustment by using Color Centro
Tips
-
Only one of the above is available.
To perform calibration by using Color Centro, disable Color Density Control.
This section explains the manual calibration using the Controller function.
. Meaning and Purpose of Controller Calibration
Measure the output density of C, M, Y, and K colors on a chart using the instrument, and give the results to
the Controller as feedback. Based on this feedback, the Controller automatically calibrates the output density
with reference to the predefined target density. This calibration enables output close to the target density.
. When to perform
- Every 1,000 to 2,000 sheets printed
-
Before printing an important job that requires strict color reproducibility

.Precautions
- Color output density can fluctuate over the course of a day due to humidity, temperature, and other
conditions. Paper type, thickness, and screen may also affect color output density.
- Perform the advanced Controller calibration several times a year.
- To reproduce stable colors, make other image quality adjustments as necessary, such as when chang-
ing screens or papers or when hue is important. For details, refer to page 3-6, page 3-3, and page 3-4.
