Adjusting the Contrast
Contrast is the relative difference between light and dark areas in an image.
To increase or reduce the contrast of the copies:
1. Press the
Services Home button, then touch Copy.

contrast, move the Manual Contrast slider up or down. The middle position on the slider,
Normal, does not change the contrast.
