Scanners types
Drum
Scanner - A drum scanner is usually found in a professional printing
business, because they provide the highest level of image quality available.
They are used with a cylindrical drum that rotates past sensing elements to
complete scanning jobs. They are more on the expensive side and they are much
more advanced than typical desktop scanning.
The flatbed scanner
is the most popular type, and the flat desktop design gives you a lot of scanning area.
Items to be scanned are placed on a glass plate, like a copier, so you can scan
multiple items of various shape and sizes, with the largest paper size being
either a letter or legal page, depending on the model. Some models even include
a transparency adapter to scan slides, x-rays or other transparent originals.
Flatbed scanners are highly recommended, if you are going to scan a good number
of graphics or separate pieces of text. Flatbed scanners are available with a
SCSI, Parallel Port or USB Port Connector.
Sheet fed Scanner is fed a piece of paper into it, much like a fax machine. Sheet fed scanners
can only handle one piece of paper at a time, although some models come with
built-in automatic document feeder (ADF) to scan multiple pages unattended.

Digital
Cameras
:
Digital cameras are a versatile tool that can produce superior
quality images. Though slower and more difficult to use than user types of
scanners, digital cameras are adaptable to a wide array of documents and
objects. Most fragile materials can be safely captured, though the need to
provide external lighting means. Digital camera technology continues to improve,
helped along by the growing consumer market.
