Introduction to Scanners
A scanner is an external device used to record data on to the computer. The data can inclued photographs, book pages, and other images already on a piece of paper. The scanner is like a copy machine, but instead of printing the item on a piece of a paper, the digital image gets placed on the computer screen. Items are scanned, transmitted from the scanner to the computer, by two types of scanners, a flatbed scanner and a sheetfed scanner. A flatbed scanner can scan paper documents, books, photographs and other flat objects, as well as photgraphic slides with the additional slide attatchment. A sheetfed scanner can only scan flat pieces of paper including documents, newspaper and magazine clippings and photgraphs.
There are many components to a scanner including:
- bed: the glass screen that documents are placed on
- lid: the top of the scanner that is closed in order to scan a document clearly
- function bar: the place where the buttons are located
- functions: the buttons that can be pressed in order to scan, print or email the document. Some scanners do not have all of these functions.
- power switch: the power button which is normally located in the back of the scanner
