How does a fax machine work?
The idea of fax machines has been around since 1842, when Alexander Bain invented a machine capable of receiving signals from a telegraph wire and translating them into images on paper. Fax machines provide an easy way to send documents to any phone number equipped with a fax machine. A fax machine works by scanning each outgoing page and converting the image into a series of light and dark dots. This pattern is then translated into audio tones, and sent over regular phone lines. The receiving fax “hears” the tones, pieces the grid together, and prints the total number of dots. The resulting document is a black and white likeness of the original page.

A fax machine, also known as telefax is one of the devices that you can use to send or receive the exact copies of text, images, drawings etc. Since this technology uses the telephone network, you can send printed documents to any remote fax machine on the network. Although internet based telecommunications are widely becoming popular nowadays, fax machines are still used in offices for sending very important documents. As such, it is a good idea to know the mechanism of this wonderful office equipment.
