Operating VRS

VirtualReScan (VRS) User’s Guide

 Black: All background color is changed to black.

 Automatic: All background pixels are smoothed to the same value,

representing an average of the detected background colors. This selection

is appropriate only when minor variations exist in the background color.

Note If you select Automatic, the results may vary, according to the color

detected in the background region of the scanned document.

4 If you selected Automatic in the previous step, the results will be directly

affected by the Snap to White setting, as follows:

 If Snap to White is selected and the image background is close to white,

the resulting background color is white.

 If Snap to White is selected and the background is not close to white, the

background color is set to a smoothed color value determined by the

scanner.

 If Snap to White is not selected, the background color is set to a smoothed

color value representing an aggregate of the detected background colors.

Note The Snap to White feature is not available with all scanners.

5 Do one of the following to adjust the Background Color Sensitivity setting:

 Move the slider to the left to decrease the level of background region

processing in color documents. A low value decreases the likelihood that a

pixel will be determined to be part of the image background.

 Move the slider to the right to increase the level of background region

processing in color documents. A high value increases the likelihood that

a pixel will be determined to be part of the image background.

 Click the arrows of the text box to increase or decrease the Background

Color Sensitivity value.

 Click in the Background Color Sensitivity text box and type a value.

6 Click OK.

Using the Blank Page Panel

Use the Blank Page panel to enable automatic detection and deletion of blank pages, a

feature that is especially useful for batch scanning in duplex mode. VRS can detect

You use the Content Sensitivity setting to control how sensitive VRS is to page

content. For example, you can configure VRS to ignore small amounts of content, such

as speckles. As a result, a speckled page is considered blank, resulting in automatic
