VRS User’s Manual

Changes to the Background panel are handled according to 

circumstances under which the VRS Interactive Viewer launched. If the 

viewer opened as the result of an exception, changes apply to the exception 

image only. If the viewer opened because you selected Preview or First Page 

mode, changes apply to all subsequent scans. Upon restart, the Background 

panel is reset to the settings associated with the last selected profile.

Use the Blank Page panel to enable automatic deletion of blank pages, a feature that is 

intended for batch scanning in duplex mode. VRS will detect and delete a blank page, 

based on its assessment of its content. 

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

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

as speckles, so that a speckled page would be considered blank, resulting in deletion. 

If desired, you can also configure VRS to detect small amounts of content, in which 

case the same speckled page may not be considered blank and it would not be 

deleted. When VRS evaluates the page content, the background color is ignored.

Some scanners include their own blank page deletion feature. If you are using VRS 

with such a scanner, we do not recommend that both blank page deletion features be 

enabled at the same time. For best results, select blank page deletion from VRS and 

disable the counterpart feature that is available from the scanner.

The availability of the Blank Page panel depends upon your VRS license, as 

well as your scanning mode selection. If your VRS license and scanning mode give 
you access to the Blank Page panel, it will be available only in Preview or First Page 

mode; you cannot access the Blank Page panel while scanning is in progress.
