A fax machine (or facsimile machine) is a device "that transmit[s] and receive[s] printed or pictorial matter on documents from one location to another, typically over telephone lines.”[1]


Such devices "transmit the material by scanning input documents and producing a series of digital pulses electrically related to the scanned printed or pictorial images. The digital pulses are sent via wire to a receiving machine which, when synchronized with the sending machine, is able to reproduce the transmitted document.”[2]
