The FAX machine as we know it is an outgrowth of wire photo machines of 1920's and 1930's. Same principle. After that was weather fax which is also sent by shortwave to ships today. In all these an original drawing (weather map, newspaper, etc. or a B/W photo) was set on a drum. This was sent to spinning and a tightly focused beam of light was aimed at the item at one end. A synchronizing signal (usually based on 60 Hz power line frequency) was sent and then the light was moved down as the drum was spun, using gears that made picture scan in a fixed speed. A TV picture is produced in a similar but much faster method - the lines are painted across screen then moved down and across, etc. by a beam of electrons hitting the florescent screen. On the old style FAX (facsimile transmission) the light reflected off the paper and hit a photo cell. This generated a weak electric signal - more if white area was lit, less if dark area was lit. This was amplified and was caused to modulate at one. This was decoded at end and drove a lamp that was aimed at photo paper or sensitive flimsy thermal paper or a stylus and carbon paper to reproduce the image.
Flat bed scanners of today have the light fixed side to side, but moves down the paper to give best light where the pickup photodiode is scanning at the moment. The paper orig. document is fixed, while the photo cell is moved and scanned. The light/dark areas produce more or less light and this is converted to digital number stream, which then modulates a multi-tone modem and off it goes down the phone line. The earliest FAX like device was developed soon after the vacuum tube was invented and became generally available in the 1920's.
I have read of crude, experimental devices in lab work even earlier. This was just before the earliest crude TV system was developed (separately) by Dr. Lee De Forest (the inventor of the first amplifying vacuum tube - the triode - which enabled the entire electronics world; his last lab assistant was one of my mentors) and Philo Farnsworth out in the High Plains (ND?) in the 20's and early 30's. TV was broadcast in late 30's in a very limited way around NYC and a few large cities just before WW2. Radio, radar and electronics advances in WW2 brought the explosion of TV as we know it in early 50's.
Here are more opinions and answers from other FAQ Farmers:
Actually, the first fax machine was invented in 1842 by Alexander Bain who patented it in 1843. It consisted of a pendulum moving across that created an electric signal to another pendulm in sync with the first one that transmitted the signal to chemically treated paper.

The first "fax service" was a fax line between Paris and Lyons, that started around the same year that the US Civil War was ending.
The version of the "modern" fax machine was put out by Xerox around the 1960s

What improvments does the fax machine have now compared to when it was first invented?
Fax machine's functions and other mechanical features does not change much over the years.
What was invented first telephone or fax machine?
The telephone predated the fax machine by many decades.
Who invinted the fax?
The first fax machine was invented Alexander Bain in 1843.
Who invented fax machine first?
Alexander Bain
What was the date fax machine was made?
First fax machine was introduced in 1843 in England by Alexander Bain.
Where was the first fax machine invented?
The "original" version of the fax machine was invented by Alexander Bain. The first "fax service" was put into place by giovanni Caselli. Xerox is generally credited with the "modern day" fax machine in the 1960s.
Who invented the fax machine?
The first fax machine was invented in 1842 by Alexander Bain. It was patented in 1843. It consisted of a pendulum moving across that created an electric signal to another pendulm in sync with the first that transmitted the signal to chemically thread and paper. Another development was the Hellschreiber, which allowed facsimile messages to be transmitted by radio.
How did fax machines effect people in the 1950's?
The fax machine for the telephone was not invented until the 1960s. It was first marketed by the Xerox Corporations in 1964.
When was the first fax machine?
First, "Fax" is simply military shorthand for, "Facsimile (fack-simm-uh-lee). The Scot, Alexander Bain, invented the facsimile machine in the year 1843 using the technology of Samuel F.B. Morse, who had invented the telegraph machine a few years earlier. The first fax machine was created by Alexander Bain, an inventor from Scotland. He received a patent for his invention in 1843, before the telephone was invented. Though this was more than 100 years before it became a part of every day life.
What year did the fax machine get invented?
1843 was the year that an image was able to be transmitted over an electronic signal - a similar process to today's fax. By about the time the US civil was was ending, there was an image transmisison service running between Paris and Lyons. The "modern" fax machine was invented in around the mid 1960s by Xerox.
Was the person who invented the fax machine British?
Yes. The person that invented the fax machine was British. Alexander Bain invented it in 1843 in England. At that point, it was only two pens connected to a pendulum that connected to a wire.
What were the first fax machines called?
I looked this up and the nearest name I came up with was the "copying telegraph." The first fax was invented by Scottish inventor Alexander Bain in 1843. He stated in his patent for his invention "improvements in producing and regulating electric currents and improvements in timepieces and in electric printing and signal telegraphs" In layman's terms a fax machine. Several years earlier Morse had made the first telegraph and the fax machine is from this technology. The early fax sent Morse Code over telegraph wires that was decoded into text. In 1850 a London inventor received a patent for the "copying telegraph." In 1860 a fax machine called the Pantelegraph sent the first fax between Paris and Lyon. In 1895 Ernest Hummel a watchmaker invented a competing device called the Telediagraph. Dr. Aurthur Korn in 1902 invented and improved the fax, the photoelectric fax. By 1926 RCA invented the Radiophoto that faxed using radio broadcasting technology, and on March 4, 1955 the first radio fax transmission was sent across the continent.
