System Requirements
The minimum system requirements are listed below. For
optimum performance, a faster processor and more memory
are recommended. If you’re scanning high resolution images,
you need more than the minimum available hard disk space.
Note: Color and tone reproduction are subject to the display
capability of your computer system, including the video card, monitor,
and software. See the documentation for these products for details.
