How does the scanner work?

Scanner is electronic which has function such as the engine of photocopy. The engine of photocopy produces something that the product can be looked directly by us at the paper. But, the result of the using scanner can be looked at the computer previously and then it can be changed and modified. So that the result can be better than the original, it can be saved as the file text, document and the picture.

The form and the size of the scanner are various, there is a scanner has size such as folio and has size such as postcard and moreover there is the scanner which has form such as pen. It can save up to 1000 pages and then it has transferred to the pc. It known as quiklink. The length of it is 6 inches and the weight are 3 owns. Wiz com say that the quicklink does the work more faster than the flat’s scanner.

Data had been talked why the scanner can input directly to the all of the computer’s application which has relevancy about ASCII.

At the moment, many scanners circulated in the world with the merks. They are canon, HP (Hewlett Postcard), Epson, Umax and etc.

The differences of scanner are at the technology and the resolution. The using of technology such as the using of digital knobs and etc.

This is how the scanner works:

§ While you press the mouse to beginning the scanning, it will be happen:

o The pressing of mouse from the computer will actuate the leader at engine of scanner. The engine at scanner manages process of sending to the unit of scanning.

o And then the unit of scanning put the process of sending to position appropriate to beginning the scanning.

o The flame of lamps are looked at the scanner indicate that the scanning.

o The flame of lamps are looked at the scanner indicate that scanning begin the process.

o While the lamp turns off, it indicates that the process of scanning has finished and the result can be looked directly at the monitor.

o If the result want be changed, we can changed by using the application of software. The examples are Photoshop, adobe and etc.

§ There is two differences of using the scanner, notably at the checking for colors of picture, there are :

o Scanner just one to scanning color and save all of color.

o Scanner is used to save the more color. The colors are red, green, and blue.

the first scanner more faster than the second scanner. But, it will be bad if it used to reproduction of color. Many scanners are used at 1 byte (Binary digit), 8 bytes and 24 byte more than 16 million colors. So that, if we need the best result, we are suggested to use scanner with the big of byte in order to the resolution of color is the best.
