Correct the colour tones with the ACCT function

The automatic correction colour tone (ACCT) function corrects slight colour deviations in the colour tones that can occur over time.

In order to enable the ACCT function in the future, you must first register these colour tones as a reference. It is recommended to do the registration right after print system installation. The registration procedure uses an internal sensor to measure the colour tones.

To correct slight colour deviations in the colour tones you can activate the automatic correction colour tone (ACCT) function. The ACCT function uses the values of the colour tones that are stored during the registration procedure.

This topic describes how to:

• Register the colour tones for the ACCT function
