What is Fax Machine
In our daily life, lots of time we heard about a gadget called FAX machine, but numerous among us don’t know the exact concept of FAX machine and its history. So today lets discuss about FAX machine, I am going to share all the information which I know about this unique gadget and also requesting all the followers and daily visitors of this site to add their knowledge about this. FAX word comes from a technical definition “a method of encoding the data and then transmitting it over the IP (Internet Protocol) or by satellite broadcast, and receiving the copy of the message which is either text or picture or photograph or anything.”
How Fax Machine Invented
The first fax machine was invented by Scottish mechanic Alexander Bain in early 18th century.But, in 1843, Alexander Bain finally received a British patent for “improvements in producing and regulating electric currents and improvements in timepieces and in electric printing and signal telegraphs”, which is known as a fax machine.

Fax Machine Working Principle
Alexander Bain uses the concept of electrochemistry and mechanics, as he was the master of those during his days as a clock maker. He used the pendulum’s swing for making the first fax machine. But later he invented the chemical telegraph, which would be modified to become the very first FAX machine. At first this machine simply sent “long” and “short” lines, which a telegraph operator could interpret easily. This process went successful and the electrochemical process it used became a major leap forward for future technology.
Later on he uses two pendulums for this process, which are synchronized at a distance by an electromagnet. The pendulum is fitted with a contact beneath it and swung it over the copper picture. Every time whenever this contact touches the copper image, it would send an electrical impulse which running over the wire to the identically synchronized pendulum swinging over some chemically treated paper. The chemical used in the paper darkened when touched by the energized pendulum. Both the sending picture and the receiving paper moved beneath each pendulum by 1 mm distance following each pendulum swing, resulting in a “scan” of the original and a copy printed on the other end, which eventually resulted in the copper image from the sending pendulum being duplicated on the paper.
At that time, Bain used nitrate ammonia solution for treating the paper that received the picture. When touched by the electrical impulse, the solution decomposed leaving a bluish stain; this created the first fax page.
