Black Detection
The Black Detection option allows you to specify whether or not to detect black-and-white pages before printing your job. To use this option, set Color Mode to Standard Color or Expert Color.

• Off: Select Off if your job consists of black-only text pages combined with a significant number of color pages.

•

On: Select On if you are printing a predominantly black-and-white job. Black-and-white only pages will print with the proper billing information.
