Recommended Equipment Your scanner is sufficient for most scanning needs, but if you are not satisified 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, see your dealer or an experienced scanner user. RAM and hard disk size Scanned images can 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 need 24-bit color, also called true color or millions of colors, to produce the highest quality image reproductions. Scanner Basics 2-7

Recommended Equipment
Your scanner is sufficient for most scanning needs, but if you
are not satisified 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, see your dealer or an
experienced scanner user.
RAM and hard disk size
Scanned images can 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 need 24-bit color, also called true
color or millions of colors, to produce the highest quality image
reproductions.
