Configuring the scan task to skip blank pages

In Datacap Navigator, you can configure the scan task to skip scanning the blank pages, for scanners that support that capability. The Skip Blank Pages option is available in the Advanced scanner settings. After you configure this option, the setting is persisted.

Complete the following steps in Datacap Navigator:
  1. Add the line of code highlighted in the following code-snippet as the last child element of the ScannerSet paragraph in your application scan task XML.
    Note: For out-of-the-box (OOTB) application TravelDocs, you should update the nscan.set.xml file. 
    <V label="Enable Autofeeder" n="Autofeed" tip="Controls scanner source
 - manual vs. autofeeder option" type="checkbox">1</V> 
<V label="Use Duplex Mode" n="Duplex" tip="When enabled - scans both 
sides of the image - duplex mode" type="checkbox">0</V> 
<V label="Pixel Type" n="PixelType" tip="Specify pixel type for scanning
 (0-BnW, 1-Grayscale, 2-RGB)" type="text">0</V> 
<V label="Bit Depth" n="Bits" tip="Specify bitdepth for above image type" 
type="text">1</V> 
<V label="Image Resolution DPI" n="Resolution" tip="Specify image resolution
 (X and Y resolution assumed the same) DPI" type="text">200</V> 
<V label="Paper Size" n="PaperSize" tip="Specify paper size for scanning
 (0-none, 1-A4, 2-JISB5)" type="text">0</V> 
<V label="Image format" n="Extension" 
tip="Specify extension for the scanned images: tif, jpeg, bmp, png" 
type="text">tif</V> 
<V label="Skip Blank Pages" n="SkipBlankPages" 
tip="Specify whether to discard blank pages, default is do not discard. 
For some scanners, duplex must be unchecked for this to be enabled." 
type="checkbox">0</V>
  2. Take a backup of DatacapWebPlugin.jar file before proceeding to update it, in case you need to revert the change later.
  3. Stop the IBM WebSphere Application Server service.
  4. Replace the updated DatacapWebPlugin.jar in the Datacap installation folder.
    Note: Example: C:\Datacap\tmweb.java
  5. Start the IBM WebSphere Application Server service.
  6. Log in to admin desktop.
    Note: Example URL of Admin desktop: http://localhost:9080/navigator/?desktop=admin
  7. Click on Plug-ins, and select the Datacap Navigator. Click Edit, then Load. Next click Save and Close. Next, click Close to exit and then log out from the application.
To test the Skip Blank Pages feature, perform the following steps:
  1. Log in to the Datacap Desktop.
  2. To update the skip blank pages value, go to NScan application.
  3. Open the Advanced tab. In the section Scanner Setup, select or clear the Skip Blank Pages check box.
  4. Save the settings. Run the scan task to verify that the blank pages are skipped during scanning.
Note: If you want to revert this feature in the Datacap Navigator, complete the steps 3 - 7 using the backed-up copy of DatacapWebPlugin.jar.
