Brightness

The Brightness option allows you to adjust the image brightness, making it lighter or darker.

Adjust the brightness setting by dragging the Brightness sliding bar in the Front Side Settings or Back Side Settings group box. Select a value from 1-255. The default is 128. The smaller the number, the darker the image. Or you can type a value (1-255) in the Brightness text box. Scan the document to check the brightness.

A darker setting is recommended for blurred character documents. With a brighter setting, background noise in a color document disappears.

NOTE: Refer to the section entitled “Automatic Threshold” for information about setting automatic brightness by Binary mode.
