Welcome to ScanGear CS-U
Welcome to Canon ScanGear CS-U 6.0 software for Windows.
ScanGear CS-U 6.0 (hereafter referred to as ScanGear CS-U) will provide
flexible, efficient image enhancement tools for scanning with your
CanoScan D646U Scanner by providing an interface with a variety of
TWAIN-compliant software applications. (TWAIN ☞p.97)
ScanGear CS-U has a number of powerful features that help you achieve
peak performance with your scanner. Using ScanGear CS-U, you can
preview and adjust an image before the image is scanned and acquired
by the parent software application.
Here is a quick summary of the important features of ScanGear CS-U:
• Two operation modes: Simple mode, which allows you to select all
optimum settings with one selection, and Advanced mode, which
allows you to create professional color and other enhancements for
artistic effects.
• Flexible, fully automatic image acquisition, and pre-scan image
manipulation prior to passing data to the image application
• TWAIN 1.6 compliant
• Text Enhanced mode for OCR applications
• Canon ColorGear (color matching software technology)
• Automatic preview or preview image cache
• ScanGear CS-U can run with or without its main window,
depending on the acquiring application.

Normally when you start a scanning job, you will see the ScanGear CS-U
main window with its toolbar, Preview Area, and tabs.
However, some software applications may not open the ScanGear CS-U
main window. When this occurs you cannot use the settings described in
this user’s guide because the host software application will provide the
settings so you can change the image after it is acquired. When a
software application uses ScanGear CS-U without opening the ScanGear
CS-U main window, this is called the windowless mode.
