light source underneath the picture or document illuminates the image. space white or black reflect more light than do inked and colored area.
a motor moves the scan head underneath the page.when the scan head is moving it capture light that was reflected from individual areas of the page about 1/90,000 of an inch.
A flat bed scanner is a machine upon which a document such as a business letter or a drawing made on paper is laid flat (usually face-down) so that a bar of light can pass under it, allowing sensors to record a digital recipe to a hard disk. This recipe can later be recalled for printing or digital alteration of the document. The flat bed can be compared to the drum scanner, which spins the document on a cylinder, against a stationary light fixture. There are also 3-D scanners and bar-code scanners.
Spraying the frame of a metal bed is quite tricky. You can use a metal paint primer. Most paint professionals use "Flat paint" as a primer because it mixes with other products. So no worries on the rust preventative enamels and latex enamels.
Sheet-fed
Three examples of prepress image capture devices are drum scanner, flatbed scanner, and scanning back for large format camera. The price of changing a print image during prepress is normally 10% of what it would cost on press.
scanner for your computer
The limitations of a camera and scanner are rather basic, first I'm going to be talking about the camera, which is a small portable device, which is used to take images and manipulate them which the software the camera comes with. Finally the scanner is a large device, which is portable but rarely taken from place to place because of the size of the scanner, this is used to transfer objects which you can hold into the computer e.g. documents, images etc.
True.

A scanner can be used to scan almost anything. A flat bed scanner could be used to scan a piece of paper, a book, a picture, some of are capable of scanning a small figurine, and documents (as long as it's legal for them to be scanned).
The typical printer does not have a "scanner". It simply connects to your desk top or laptop. There are what is referred to as "all in ones" that provide the ability to print, send/receive fax, and copy/scan. These units will have a glass flat bed on top with a hinged cover.
A scanner is the best way. If the pictures are old, you will probably want to use a flat-bed scanner (one that you lay the pictures on) as opposed to a sheet-fed scanner (that would take a chance of damaging the pictures as they were fed through).If you do not have a scanner, you could possibly get them into your computer if you have a good digital camera and a tripod.
It is better to buy an all in one printer because it saves space and money. You can read more at www.consumersearch.com/multifunction-printer-reviews
The page of text is first scanned and then an Optical Character Recognition (OCR) software program is used to convert the scanned text file into a machine-encoded text file that the user can edit and make changes to. So the device is a scanner, usually a flat-bed scanner, or a hand-held scanner, or a printer that has an inbuilt scanner.
depends if it is short bed or a long bed
