Sizing Up Your System

Your scanner is sufficient for most scanning needs, but if you are
not satisfied with the quality of the images on your monitor or
with the speed of image processing, read this section. While it
does not contain specific recommendations, it describes various
possibilities for improving your scanning system. For further
information, seek advice from your dealer or an experienced
scanner user.

RAM and hard disk size

Scanned images use much more memory than text files, so
you may need more RAM (Random Access Memory) in your
computer and a larger hard disk than you have used previously.

Accelerator boards

In addition to memory, processing speed is important because
large files take longer to process than small ones. Therefore, you
may want to add an accelerator board to your computer.
