The scanner is a very important multimedia component to the PC system and is a must if you want to make copies of pictures or any type of media. Scanners have developed into a commonplace computer accessory capable of not only converting photos into digital images but also of photocopying, faxing, importing printed pages into word processing documents, and even posting photos to Web pages. In fact, a scanner can be just about the most versatile addition you can make to a PC. With the push of a button, a good color scanner can copy any type of document, report, or photograph you need transferred to the Internet or computer file.
A scanner is a device that captures and converts images to a computer format. Its eyes are an array of photosensitive cells that detect light reflected off or transmitted through the object being scanned. This array of receptors, referred to as a charged-couple device (CCD), measures light intensity and converts it into an electrical charge. The photosensitive array in a sheet fed 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.
Portable sheet fed scanner is reminiscent of the mimeograph of old, where a paper document is threaded into a rolling mechanism. As the paper moves through the scanner the information is collected and presented in its original format on your screen. Depending upon the accompanying software, the material may be presented in a word processing document or image viewer.Sheet feds are available in both monochrome and colour.Sheet fed scanners are nicely compact so they’re good for limited spaces.

Sheet fed scanners have grown in popularity in recent years, particularly for small office or domestic use as they are reasonably priced, can scan full-sized documents and are compact, requiring limited desk space. Most models of sheet fed scanners have an inbuilt document feeder to overcome the problem of manually feeding one sheet of paper at a time. However the actual process or scanning with a sheet fed scanner may result in distortion as the image to be scanned moves over the scanning heads.
