Surprising Victorian Origins
The first seeds of facsimile technology were sown by a Scottish inventor named Alexander Bain. In 1843, while the world was still marveling at the electric telegraph, Bain patented a device he called the “Electric Printing Telegraph.” His ingenious concept involved using a pendulum synchronized with another at the receiving end. A stylus, scanning over a surface with raised, electrically conductive letters, would transmit pulses corresponding to the image. The receiving pendulum, equipped with chemically treated paper, would recreate the image line by line as the electric current caused discoloration. While Bain’s invention was groundbreaking, it wasn’t immediately practical for widespread use. However, it laid the fundamental groundwork: scanning an original document and transmitting its likeness electrically to be reproduced elsewhere.It might seem astonishing, but the core concept of sending an image over wires was patented by Alexander Bain in 1843. This was more than three decades before Alexander Graham Bell patented the telephone. Bain’s work truly pioneered the idea of remote image transmission.Further developments followed. Italian physicist Giovanni Caselli built upon Bain’s work, creating the “Pantelegraph.” Unlike Bain’s experimental device, Caselli’s Pantelegraph saw actual commercial service between Paris and Lyon starting in 1865. It could transmit handwriting and even simple drawings over telegraph lines, representing the first practical, albeit rudimentary, fax service. It remained cumbersome and slow, but it proved the concept was viable.
Refinements and Early Applications
The late 19th and early 20th centuries saw continued refinement. Inventors explored different scanning methods and transmission techniques. A significant step was the application of phototelegraphy – using photoelectric cells to convert variations in light reflected from (or passed through) an image into electrical signals. German physicist Arthur Korn successfully transmitted a photograph electrically over a significant distance in 1902, paving the way for “wirephoto” services used by newspapers. Édouard Belin in France developed the Belinograph around 1913, which became popular for transmitting news photographs over telephone or telegraph lines, and later via radio waves (radiophoto). These early systems were specialized, expensive, and primarily used by large organizations like news agencies and government bodies. They weren’t the desktop machines we’d later recognize.Moving Towards the Office
The mid-20th century saw corporations begin experimenting with facsimile technology for business purposes. RCA introduced its “Radiophoto” system, and Western Union also developed fax capabilities. The primary hurdles remained cost, speed, and lack of standardization. Sending a single page could take several minutes, and machines from different manufacturers often couldn’t communicate with each other. Xerox, already a giant in photocopying, entered the fax arena in the 1960s. Their 1964 introduction of the LDX (Long Distance Xerography) system was a landmark. While still large and expensive, it offered better quality and speed than many predecessors. Two years later, Xerox launched the Magnafax Telecopier, arguably the first machine resembling the modern office fax. It was smaller, connected to a standard telephone line, and could transmit a page in about six minutes. Still slow by later standards, but a significant step towards office integration.Standardization and the Japanese Revolution
The real explosion in fax machine adoption hinged on two critical developments: standardization and affordability. The International Telegraph and Telephone Consultative Committee (CCITT), now known as the ITU-T, established crucial standards for fax transmission.- Group 1 (G1): Introduced in 1968, based on analog technology, taking about six minutes per page.
- Group 2 (G2): Standardized in 1976, still analog but faster, around three minutes per page.
- Group 3 (G3): The game-changer, standardized in 1980. This used digital compression techniques (Modified Huffman and Modified READ) to transmit over analog phone lines, drastically reducing transmission time to under a minute per page, often much faster.
The Heyday of the Fax
From the mid-1980s through the late 1990s, the fax machine reigned supreme. It became as common in offices as the telephone or the photocopier. Its advantages were clear:- Speed: Compared to postal mail (“snail mail”), fax was virtually instantaneous. Sending contracts, invoices, orders, or urgent memos across town or across the world took minutes, not days.
- Simplicity: Using a fax machine was relatively straightforward – dial a number, insert the document, press send.
- Hard Copy Verification: It provided a physical copy at both ends, often considered more tangible and legally binding than emerging digital alternatives at the time. Confirmation pages provided proof of transmission.
The Inevitable Decline
Technology, however, rarely stands still. The very forces that enabled the fax machine’s rise – digital technology and telecommunications networks – eventually led to its decline. The primary catalyst was the internet and the proliferation of email. As internet access became widespread and email became a standard communication tool in the late 1990s and early 2000s, its advantages over fax became apparent:- Cost: Sending an email attachment was essentially free, unlike the per-minute phone line charges associated with faxing, especially for long-distance transmissions.
- Quality: Digital documents sent via email retained their original quality, whereas faxes often suffered degradation, especially after multiple transmissions.
- Convenience: Documents could be created, sent, received, and stored entirely digitally, eliminating the need for paper, printing, and physical filing. Scanners allowed existing paper documents to be digitized easily.
- Integration: Email integrated seamlessly with other digital workflows.
