A scanner is a digital device that converts films, documents and photographic prints to digital images. It scans documents, which can be sent to a computer, printer, flash drive or email address.

Scanned files can be stored on a computer’s hard drive, flash drive or shared network folders. An operator can send scanned documents to a client computer using web services. A flatbed scanner equipped with a fax feature can send a fax to more than one destination.

A flatbed scanner with printing capabilities can serve as a home printer, allowing the user to make adjustments to the document. Scanners with optical character recognition software, known as OCR, can scan documents and convert them to editable text.

A scanner can even scan 3D objects such as cloth, shells and coins that are somewhat flat.
