Hello i m BAL and i am a cool dude

In this blog i will be talking about different types of scanners and how each different scanner functions.

The first scanner that i will talking about is the FLATBED SCANNER this scanner is often usedto scan books and photographs. The FLATBED SCANNER has a sheet feeder to scan multiple images. The FLATBED SCANNER works like this it has a scanner head which consists of an array of image sensors, which lie beneath the glass and move along the item, whilst capturing the image.

The second scanner is HANDHELD SCANNER which a scanner which is portable small scanner. When using this scanner it is difficult to scan an image so you need to carefully pass the scanner head across the item that you want to scan.When a largeritem is scanned which is bigger than the handhel scanners head you must make more than one pass to capture the full image.  It could be very difficult to recreate the image but the images must beput back into one full single image of the item which was scanned.

The third types of scanner is a DRUM SCANNER which produces a high-quality transfer of an image. This scanner is usually used commercially and many drum scanner can also be used for high-end reproduction. An example of this could be phototgraphs in museums.  If you want to scan a image using the drum scanner, you need to attach the image to a revolving drumor load into a supporting canister. the drum inside the drum scanner roatates at very high speeds across optical scanner. The optical scanner carries on moving slowly across the drum until the whole of the image is completed and is captured. The captured image is then reproduced by the computer as a digital image file.

The last type of printer is ALL-in-one scanner which can scan,print send faxes and make copies, This scanner can do all the jobs that the scanners do above.
