Using Image Setup
Image Setup for i200 Series Scanners provides four tabs: Filters, Check,
Mask, and Color Dropout. Following are descriptions of these tabs.
NOTE: The Delete button on the Image Setup dialog box allows you to delete
an image setup and remove it from the list of available image setups.
Filters tab
The Filters tab is different for bitonal and color/grayscale image setup.

bitonal image setup
NOTE: The iThresholding button is only available with the i280 Scanner.
Threshold —threshold controls the lightness and darkness of the
background in an image. As the threshold value increases, more of the darker
grays in the image turn black. As the threshold value decreases, fewer darker
grays turn black. Enter a value between 0 and 255. The default is “90.”
Contrast —contrast enhances the edges contained in a document.
Increasing the contrast level sharpens the image edges. Decreasing the
contrast level softens the image. Enter a value between 0 and 100. The
default is “50.”
iThresholding —click to enable iThresholding. When
iThresholding is enabled, the scanner automatically determines the optimal
Threshold setting for each scanned page, thereby improving overall scanning
productivity and image quality. With the iThresholding feature, the need to
make adjustments to the Threshold setting when scanning mixed documents
of different colored or shaded backgrounds is greatly reduced.
When iThresholding is enabled, the Threshold and Image processing settings
are grayed out. The scanner will automatically perform Adaptive thresholding
processing and will determine the optimal Threshold setting.
