Adjusting The Brightness And Contrast - Xerox DocuMate 3220 User Manual

Advanced:
The resolution panel also includes an advanced setting for Moiré patterns. Moiré patterns are wavy,
rippled lines that sometimes appear on the scanned images of photographs or illustrations, particularly
newspaper and magazine illustrations. To scan the image and limit or eliminate moiré patterns, select
the Reduce Moiré option. This option is not available for high resolution settings.

Adjusting the Brightness and Contrast

Increasing the Brightness level makes the image lighter and decreasing the brightness level makes the
image darker.
Increasing the Contrast emphasizes the difference between the lighter and darker regions in an image.
Decreasing the contrast de-emphasizes the difference between the lighter and darker regions. Contrast
is used in conjunction with Brightness. Contrast settings are only available for Color and Grayscale
configurations.
To adjust the brightness and contrast:
• Move the Brightness slider to the left to make the item darker or to the right to make the item
lighter.
• Move the Contrast slider to the left to decrease the contrast or to the right to increase the
contrast.
• You can also type a number directly into the brightness or contrast setting boxes, or click the up
and down arrows next to the box to increase or decrease the setting.
• Click Reset to return the settings to their original numbers.
