CANNER
Best suited for most business applications, this
scanner looks similar to a desktop photocopier.
You place a document on glass and close the
cover, and the scan head moves underneath it
along the “bed” of the scanner. Originally a gray
scale technology, color models are now just as
affordable, offering the widest range of uses in a
desktop system. A flatbed color scanner is ideal for
virtually all uses, from simple line drawings to
complex full-color illustrations and photographs.

You hold this type of scanner in your hand and
run it over the image. The scan head is limited in
size, usually just four inches wide, so you have to
piece together wider images using your software.
While this is the least expensive of scanner
technologies, you’ll need a steady hand to avoid
distortions caused by shaky movement.

Developed specifically for use with OCR
applications, this scanner feeds sheets of paper
into the unit and scans them automatically. You
can get similar results by adding an optional
automatic document feeder (ADF) to your
flatbed scanner.
