Who invented the Fax Machine?

The term fax machine is the short form for facsimile machine. This device can send copies of documents over a telephone line. The first facsimile machine was invented by Alexander Bain, a Scottish inventor in 1846. He was born in Watten in Scotland and has invented many devices that can make practical use of electricity.

Following this invention, in 1851, Fredrick Bakewell unveiled his system that was a modified version of Bain’s machine. Richard H Ranger, who worked for Radio Corporation of America (RCA), invented the radio facsimile, which later came to be known as ‘fax’, in the form that we know it today. This could send documents and pictures across oceans without the help of cables.

Initially the fax machine used the analogue format like it was in an analog television but now these machines are no longer in use. Today we use the digital fax machines and these machines are the successor of the earlier analog machines. Digital fax machines use compression techniques in the digital format. Transmission rate is much faster and the reproduction quality is also much better. The time taken to transmit a text matter is very less.

Modern fax machine has a sensor which reads a paper inserted through a mechanism to feed paper. The typed or written matter or graphics on the white paper is encoded by reader devices and transmitted through telephone lines. At the other end, the matter is decoded and a copy of the matter is made available through a printer.
