Note When Blank Page Detection is enabled without deletion, the ability to

notify the scanning application is supported only for ImageControls-based

applications, rather than ISIS- or TWAIN-based applications.

4 Adjust the Content Sensitivity setting to determine how sensitive VRS is to

page content. The possible values range from 1 to 100. A high sensitivity

value means that VRS is very sensitive to small amounts of content, even if it

is scattered on a page. As a result, such a page would not be considered to be

blank. A low sensitivity value means that VRS is less likely to detect small

amounts of content on a page. As a result, such a page would be considered

blank. You can adjust the Content Sensitivity setting by doing one of the

following:

 Move the slider to the left to decrease the likelihood of detecting small

amounts of content on a page.

 Move the slider to the right to increase the likelihood of detecting small

amounts of content on a page.

 Click the arrows in the text box to increase or decrease the Content

Sensitivity value.

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

The message “Page Content Detected” or “Page Content Not Detected”

indicates whether or not VRS considers the preview image to be blank based

on the current Content Sensitivity setting. You can adjust the Content

Sensitivity setting to locate the threshold at which VRS detects content on a

page.

5 Select the Ignore Holes check box if you want hole marks to be disregarded

when VRS determines if a page is blank. If the check box is not selected, a

page that is blank except for hole marks near the edges may not be considered

blank by VRS.

6 Click OK.

Note If a page is removed as a result of blank page deletion, any exceptions

that it may have generated for other reasons are disregarded and canceled.

Any exceptions related to the image on the reverse side of the blank page are

processed as usual.

When You Can Expect to See Blank Page Images in the Viewer

When the blank page deletion feature is in effect, blank pages are automatically

deleted and you do not see them in the image viewer. However, when you set the QC
