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
Only one of the above is available.
To perform calibration by using Color Centro, disable Color Density Control.
For details, refer to Periodical Adjustment (Automatic Adjustment).
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

Coated GL 128 g/m2 / 33 lb Bond (A3, Loaded in Tray 1)
* The sample screen may be different from the actual display depending on your system environment and application version/revision.
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 changing screens or papers or when hue is important. For details, refer to Adjustment Flow when changing the screen, Regular adjustment flow: Normal, and Regular adjustment flow: High Precision.
If controller calibration, Adjustment Flow when changing the screen, Regular adjustment flow: Normal, or Regular adjustment flow: High Precision does not improve color stability, creating a profile may help solve the problem.
