General
• Lock settings—this option prevents the user from making changes to the options in the scanner interface.
When the interface opens, only the scanning Presets will be available for a user to select and use for
scanning.
• Default preset—select the preset you want to have be the default displayed options in the scanner interface
each time it opens.
TWAIN Driver
• Auto transfer—scanning and transfer starts when the scanner detects paper.
• Auto close on transfer—the interface closes automatically when scanning is complete.
• Force UI-less—select this option to prevent this scanner interface from opening when you initiate a scan in
the scanning application. This option will only work if your scanning application supports UI-less scanning.
You may also need to select Auto close on transfer complete for this option to work.
• Preset overrides capabilities—some scanning applications have the option to adjust the scan settings and
scan without opening this scanner interface. The next time this interface opens, the last used settings will
match the application settings that were used to scan. Select this option to have the settings reset to the last
ones used when this interface was open.
• Enable user compression—this option is enabled only if the scanner and the software allow manual
adjustment of the image compression.
• Remember compression—when a compression option is available for user adjustment, it cannot be saved as
part of a preset. Select this option to have the compression setting saved.
WIA Driver
• Use default WIA UI—select this option to display the Microsoft WIA interface instead of the TWAIN
interface in WIA 2.0 applications.
• Emulate WIA 1.0—select this option to display the TWAIN interface for WIA 1.0 compatible applications.
When this option is selected, WIA 2.0 applications will use the Microsoft WIA interface.
