Calibrating the Gradation
Gradation is the gradual changing of the color depth and brightness. If the gradation is not reproduced correctly and the printed data greatly differs from the source data or original, calibrate the gradation (calibration).
You cannot perform calibration while printing or scanning or when there is insufficient toner.

Paper Sizes and Types Usable for Calibration
Size: A4, LTR

Use the control panel to perform calibration. You cannot perform calibration using Remote UI from a computer.
IMPORTANT
Toner is used during calibration.
Performing frequent calibration may affect the lifetime of the toner.
If the symptoms do not improve even after performing calibration, the remaining amount of toner may be low. It is recommended to check the remaining amount of toner, and replace any toner containers, as needed.
