TWAIN scanner driver support.
SimpleIndex will work with both TWAIN and ISIS scanner drivers. TWAIN is more common and works with virtually all scanner models. ISIS is designed for high speed document scanners. Most sheetfed scanners support ISIS.
ISIS is much faster and has more features than TWAIN, and is the preferred way to scan documents. ISIS scanning is included with SimpleIndex Full or is available as an add-on for other versions.
This is done through the TWAIN or ISIS settings for your scanner. To access these settings select “Display Scanner Settings” from the “Scan” file menu. Next click the “Run Job” button and before the scanning process starts your scanners TWAIN or ISIS settings dialog box will appear.
Every TWAIN or ISIS dialog is different, but any of them have a clear option for changing page size or auto detecting page size.
This is done using the “Min File Size” setting on the Batch tab. This setting uses the image file size in bytes to determine which files are blank pages. For 200dpi, compressed, black & white TIFF images (the default format used by SimpleIndex) this is usually around 2000 bytes.
Depending on your scanner settings and how much black is in your images, blank pages could be significantly larger. If you are scanning small pages the margin for error will be less. You will want to do some trial and error testing to ensure the setting is right for your images.
