When you click [Preferences...], the [Preferences] dialog appears.
This dialog allows you to specify advanced settings for the ScanGear functions.
[Scanner] tab
[Quiet Mode]
This mode reduces scanning noises by slowing down the scanner during document preview and scanning. This checkbox is not selected by default.
[Calibration Settings]
When you set [Execute at Every Scan] to [ON], the machine calibrates the scanner before each preview or scan execution and makes adjustments so that the scanned image is reproduced with correct color tones. This setting is [OFF] by default.
[Color Settings] tab
Color adjustment
Select one of the following options. It defaults to [Recommended].
[Recommended]
Recreates the document color vividly on the screen. It is recommended to select this option under normal circumstances.
[None]
ScanGear performs no color correction.
You cannot select this if [Black and White] is selected for [Color Mode].
[Monitor Gamma]
To adjust the brightness of display image so that it matches the characteristics of the monitor, specify the gamma value (0.10 to 10.00) of that monitor (display).
Specify this setting if the original color tones are different from the color tones of the image displayed on the monitor.
Click [Defaults] to return the monitor gamma to the default value (2.20).
