As history of photocopy machine takes center stage, this journey explores the evolution of a technology that has revolutionized the way we communicate and work.
The first photocopy machines were invented in the 1700s, but it wasn’t until the 1950s that commercial photocopy machines became widely available, transforming the office environment and business operations.
Early Development and Invention of Photocopy Machines: History Of Photocopy Machine
With the advent of digital technology, photocopy machines have become an essential tool in modern offices and homes. However, have you ever wondered how these machines came to be? In this chapter, we’ll delve into the early development and invention of photocopy machines.
The concept behind the first photocopy machines was based on the principle of electrostatic photography, where a charged beam of light was used to create an electrostatic image on a surface. This technology was first demonstrated by Alexander Graf Ban, a German engineer, in 1907. Ban’s experiment involved using a beam of light to create an electrostatic image on a piece of paper, which was then used to create a negative image.
Early pioneers and innovators in the field of photocopy technology were: Harold Edgerton and Chester Carlson.
Pioneers and Innovators
Early Pioneers
The early pioneers in the field of photocopy technology made significant contributions to the development of modern photocopy machines.
- Harold Edgerton: Known as the “father of high-speed photography,” Edgerton was a pioneer in the field of electromagnetics and electrostatic photography. In 1928, he demonstrated the first high-speed camera, which was capable of taking photographs of objects in motion. This technology laid the foundation for the development of photocopy machines.
- Chester Carlson: A physicist and chemist, Carlson is credited with inventing the first electrostatic copying process in 1938. His technique involved using a beam of light to create an electrostatic image on a surface, which was then used to create a negative image.
The First Photocopy Machine
The first photocopy machine was a prototype developed by Chester Carlson in 1947. This early machine used an electrostatic process to create a copy, and it was capable of producing about 30-40 copies per minute.
- The first photocopy machine used a selenium drum coated with a thin layer of metal. When a document was placed on the drum, an electrostatic charge was transferred to the drum, creating an electrostatic image.
- The electrostatic image was then transferred to a sheet of paper, which was coated with a material called zinc sulfide. When the paper was exposed to light, the electrostatic image was recreated as a negative image.
In 1949, the first commercial photocopy machine was released, with an estimated cost of around $30,000. It wasn’t until the 1950s that photocopy machines became more affordable and accessible to the general public.
Evolution of Photocopy Machines to Xerography
The invention of the xerographic process by Chester Carlson in the 1930s revolutionized the copying industry, paving the way for the development of modern photocopy machines. Xerography, also known as electrophotography, is a dry photocopying process that uses electrostatic charges to transfer images onto paper. This innovative technology replaced earlier photocopying methods, such as contact copying and mimeography, which were time-consuming and of poor quality. Xerography offered several advantages, including high-quality images, speed, and ease of use.
Key Innovations in Xerography
Carlson’s invention involved several key innovations that made xerography possible. One of the most significant was the development of the electrostatic charge generation process, which involved rubbing a charged rod against a glass plate. This process created a latent image on the plate, which could then be transferred onto a sheet of paper. Another important innovation was the use of a light-sensitive material, known as zinc oxide, to create the latent image. This material, when exposed to light, became electrically charged and adhered to the paper.
Xerography Process
The xerography process involves several key steps. First, a document is placed face down on a drum coated with a light-sensitive material. The drum is then charged with a high voltage, creating a strong electrostatic field. A light source, such as a lamp, is directed at the document, creating a latent image on the drum. The latent image is then transferred onto a sheet of paper, which is passed through the drum. The paper becomes attracted to the drum due to the electrostatic charge and picks up the latent image.
Impact of Xerography on Photocopy Machines
The development of xerography had a profound impact on the design and functionality of photocopy machines. Modern photocopy machines use a similar xerographic process, but with significant improvements. For example, many modern machines use a solid-state drum, which eliminates the need for mechanical drums. They also use advanced light sources, such as LEDs, which provide higher intensity and longer lifespan. Additionally, modern machines often incorporate features such as automatic document feeders and duplexing, which allow for faster and more efficient copying.
Photocopy Technology Advancements (1970s-1980s)
Following the introduction of xerography, photocopy machines underwent significant improvements in speed, quality, and reliability during the 1970s and 1980s. These advancements enabled businesses and individuals to rely on photocopy machines for a wide range of applications, from document management to marketing materials.
Improvements in Photocopy Machine Speed
As technology progressed, photocopy machine speeds increased dramatically. Manufacturers began to integrate more advanced systems, including improved paper handling, faster motorized parts, and advanced control systems, to enhance overall performance. This allowed users to complete tasks more efficiently, contributing to increased productivity and improved workflows.
Introduction of New Copy Modes
In addition to the introduction of higher speeds, manufacturers also began to develop new copy modes that catered to specific user needs. Some notable examples include the introduction of color copying and high-speed copying.
Notable Photocopy Machines of the Era
Several notable photocopy machines emerged during this period, showcasing the advancements in technology. Here are a few key examples:
| Model | Year | Speed | Resolution |

| IBM Copy 350 | 1977 | 7cpm | 600 x 600dpi |
| Xerox 920 | 1980 | 10cpm | 600 x 600dpi |
The Xerox 700, released in 1976, demonstrated a speed of 5 copies per minute (cpm) at a resolution of 300 x 300 dots per inch (dpi). The IBM Copy 350, introduced in 1977, offered 7cpm at a higher resolution of 600 x 600dpi. Finally, the Xerox 920, launched in 1980, pushed the speed barrier with 10cpm and maintained 600 x 600dpi resolution.
Digital Photocopy Machines and Copiers
The transition from analog to digital photocopy technology marked a significant milestone in the evolution of photocopying. Digital photocopiers, also known as digital copiers, have revolutionized the way we reproduce documents, offering improved quality, speed, and environmental benefits. This shift towards digital technology has enabled the development of more sophisticated and efficient photocopy machines.
