History of Facsimile Machines
The history of the fax machine dates back to the early days of communication technology, when people sought to send messages across distances. The development of messaging systems, from the 1600s to the 1800s, laid the groundwork for the creation of the first fax machines. In this section, we’ll explore the early beginnings of communication technology, the evolution of messaging systems, and the examples of early messaging devices that paved the way for the development of fax machines.
The Emergence of Communication Technology
Communication technology has come a long way since the 1600s, when the first telegraph systems were introduced. These early systems allowed people to send messages over short distances using a series of electrical impulses. The development of the telegraph paved the way for the creation of other communication technologies, including the telephone and, eventually, the fax machine.
- The first telegraph system was invented by Samuel Morse in the 1830s. It allowed people to send messages over short distances using a series of electrical impulses. Morse’s telegraph system used a combination of dots and dashes to represent letters and numbers, allowing people to send messages in code.
- In the 1850s, the telegraph system was expanded to cover longer distances, allowing people to send messages across cities and even across states.
- The telephone was invented in the 1870s by Alexander Graham Bell, allowing people to have real-time conversations over long distances.
Early Messaging Devices
Before the development of the fax machine, there were several other messaging devices that allowed people to send messages across distances. These devices included:
Optical Telegraphy
Optical telegraphy was a system that used a series of mechanical arms to transmit messages using a combination of lights and reflections. This system was used in the 1800s to send messages over long distances, and was an important precursor to the development of the telegraph.
The Photocopier
The photocopier was invented in the early 20th century, and allowed people to make copies of documents. While it wasn’t a messaging device per se, the photocopier laid the groundwork for the development of the first fax machines, which used a similar process to transmit images over phone lines.
The Telephone
The telephone was invented in the 1870s, and allowed people to have real-time conversations over long distances. While it wasn’t a messaging device in the classical sense, the telephone paved the way for the development of other communication technologies, including the fax machine.
Invention and Development
The invention of the first facsimile machine is often credited to Alexander Bain, a Scottish inventor who created the machine in 1843. Bain’s invention marked the beginning of a new era in communication, enabling people to transmit images over long distances and paving the way for the development of modern fax technologies.
Alexander Bain’s Invention
Alexander Bain’s facsimile machine, also known as the “Electric Printing Telegraph,” used a combination of electrical and mechanical components to transmit images over wires. The machine consisted of a scanning pen that moved along a strip of paper, tracing the Artikel of an image. This image was then transmitted over telegraph lines, where it was received by a corresponding machine that recreated the image on a second strip of paper.
Bain’s invention used a system of clockwork and electrical contacts to transmit images, demonstrating the potential of facsimile technology.
Bain’s invention was significant because it showed that it was possible to transmit images over long distances using a combination of electrical and mechanical components. This paved the way for further developments in facsimile technology.
Improvements to Bain’s Design
Frederick Bakewell, an English inventor, made significant improvements to Bain’s design. In 1858, Bakewell developed a facsimile machine that used a pantograph to enlarge and transmit images. The pantograph was a device that used a moving pen to draw a copy of an image onto a larger surface. Bakewell’s machine was able to transmit images more quickly and accurately than Bain’s original machine.
- Bakewell’s machine used a system of gears and levers to transmit images, allowing for more precise control over the transmission process.
- The pantograph used in Bakewell’s machine enabled the transmission of images with greater resolution and accuracy.
The Role of the Telegraph
The telegraph played a crucial role in the development of facsimile technology. The telegraph allowed for the transmission of electrical signals over long distances, which made it possible to transmit images using a combination of electrical and mechanical components. In the early days of facsimile technology, the telegraph was used to transmit signals between facsimile machines, allowing for the transmission of images over long distances.

Transmission of Fax Signals Using the Telegraph
The transmission of fax signals using the telegraph was a complex process that involved several components. The facsimile machine would transmit electrical signals over the telegraph lines, which were then received by a corresponding machine that recreated the image on a second strip of paper.
- The telegraph lines used for fax transmission were typically operated at a frequency of around 10 Hz, which was lower than the frequency used for telegraph communication.
- The facsimile machine used a system of diodes and transistors to amplify and transmit the electrical signals.
Comparison to Other Technologies
The fax machine was one of the several technologies that revolutionized communication in the 19th century. Alongside the telegraph and telephone, these innovations enabled people to send messages over long distances, paving the way for the modern communication landscape. While these technologies share some similarities, they also have distinct advantages and disadvantages that set them apart.
The telegraph, invented by Samuel Morse in 1837, was the first technology to allow for the transmission of messages over wires. Although it was an electromechanical system, it required manual encoding and decoding, making it a labor-intensive process. On the other hand, the telephone, invented by Alexander Graham Bell in 1876, enabled real-time voice communication over long distances. However, it only allowed for audio communication and not the transmission of visual information.
Technical Specifications of Early Communication Devices
The table below compares the technical specifications of early fax machines with other communication devices:

Technical Specifications
The technical specifications of fax machines play a crucial role in enabling fax communication. These specifications involve various components and protocols that work together to transmit images over telephone lines. In this section, we will delve into the technical components required for fax communication, including the modulator and demodulator, as well as the role of analog to digital conversion in fax transmission.
The Modulator and Demodulator
The modulator and demodulator are critical components in fax transmission. The modulator converts the analog image into a digital signal, while the demodulator converts the digital signal back into an analog image. This process is essential for fax transmission, as it enables the transmission of images over telephone lines.
A modulator typically consists of a encoder, a compressor, and a transmitter. The encoder converts the analog image into a digital signal using a combination of analog-to-digital converters (ADCs) and digital signal processors (DSPs). The compressor reduces the size of the digital signal to prepare it for transmission. Finally, the transmitter transmits the digital signal over the telephone lines.
On the receiving end, the demodulator consists of a receiver, a decompressor, and a decoder. The receiver captures the digital signal transmitted over the telephone lines. The decompressor restores the compressed digital signal to its original size. Finally, the decoder converts the digital signal back into an analog image.
Analog-to-Digital Conversion, When was a fax machine invented
Analog-to-digital conversion is a critical step in fax transmission. This process involves converting the analog image into a digital signal that can be transmitted over the telephone lines. The analog image is first converted into a digital signal using an analog-to-digital converter (ADC). The ADC samples the analog image at regular intervals and converts each sample into a digital value.
The number of samples taken per unit of time determines the resolution of the digital image. The higher the resolution, the more samples are taken, and the more detailed the digital image. However, increasing the resolution also increases the size of the digital image, which can affect transmission speed.
Transmission Protocols
In early fax machines, transmission protocols were used to control the transmission of digital images over telephone lines. These protocols included V.21, V.22, and V.27ter. V.21 was the first transmission protocol used in fax machines and allowed for transmission of faxes at a speed of 300 bits per second.
V.22 was an improvement over V.21, allowing for transmission of faxes at a speed of 1,200 bits per second. V.27ter was the final transmission protocol used in early fax machines and allowed for transmission of faxes at a speed of 7,200 bits per second.
The V.27ter transmission protocol was widely used in early fax machines and enabled transmission of high-quality images over telephone lines.
| Transmission Protocol | Transmission Speed |
|---|---|
| V.21 | 300 bits per second |
| V.22 | 1,200 bits per second |
| V.27ter | 7,200 bits per second |
- Early fax machines used transmission protocols such as V.21, V.22, and V.27ter to control the transmission of digital images over telephone lines.
