TWAIN Scanning Guide Hardware Properties and Interface Behavior
54 User’s Guide
• 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.
