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.
Video cards
A video card that is sufficient for text may not be good enough
for displaying graphic images, especially in color. If all your
scanned images look coarse on your monitor, you may want to
upgrade your video card. You will need 24-bit color, also called
true color or millions of colors, to make the highest quality image
reproductions.
