Color mode cannot be changed in applications such as OCR software
which will not display the ScanGear MF dialog box (UI off mode), and
consequently the document will be scanned with the settings in the
application. To override the application settings and scan in a specific
color mode, configure the settings here. Neither of these settings is
selected by default.
