Correct the color tones with the ACCT function

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

In order to enable the ACCT function in the future, you must first register these color 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 color tones.

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

This topic describes how to:

• Register the color tones for the ACCT function
