Scanner Type
Sheetfed Scanners
Unlike a flatbed scanner, the photosensitive array in a
sheetfed scanner is stationary, and the page being scanned
is moved over the array. This is a good type of scanner for
someone who intends to scan a lot of documents to produce
editable text. If you combine a sheetfed scanner with an
automatic document feeder (ADF), you don't need to feed in
each sheet by hand.
Sheetfeds are available in both monochrome and colour.
Although you can feed pictures or small pages into the
scanner, the scanned images can get warped so flatbeds are
still more flexible. Sheetfed scanners are nicely compact so
they're good for limited spaces. You can pick up one of
these scanners for under $150. Rapid, high volume business
models can get into the thousands.
