The History of Photocopiers
The invention of Photocopiers was made possible through the invention of two simple pieces of science. The first piece of science involved the formation of light, which is a substance that can be converted into a mechanical image. The second piece of science involved the creation of a photocopying machine. It was an American inventor named Chester Carlson who first pitched the idea to some of the world's largest companies back in the 1940s. The idea was met with a resounding lack of interest from the companies - which took Carlson years to realize.
In the photocopying process, a photoconductor gains an electrical charge where light hits it. Once the photoconductor has collected the photons, it fuses with the paper to create an "electrical copy" of the hand. Eventually, it will be transferred from one hand to another. This is the underlying principle behind photocopying. Luckily, the photocopying process is quite simple and easy to understand.
Unlike traditional photocopiers, modern photocopiers can also scan, print, and fax. The latter is becoming obsolete in the modern age, as faxing is becoming an obsolete method of communication. These multifunction units often have network connections and are called All-In-One Printers. These machines are also network-ready, allowing users to connect the photocopier to other computers via USB or folder, fax, or email.
The invention of the first photocopy was made possible by Chester Carlson in 1938. He collaborates with his friend, physicist Otto Kornei. He calls his idea electrophotography, and is granted a US patent for his invention in 1938. However, his machine takes a lot longer to copy than a traditional photo. He was rejected by 20 big companies before Battelle Memorial Institute and eventually a patent was granted.
Despite being predicted to be obsolete, photocopying remains popular in government, business, and education sectors. It is difficult to predict when photocopiers will completely disappear, but they continue to be used in every aspect of business, from creating and storing digital documents to distributing them electronically. The 1980s also saw the emergence of multifunction printers, which combined the functions of a photocopier and a printer. As the price of home office machines continues to fall, low-cost machines have dominated the market.
Colour photocopiers have a wide range of options. They can produce both coloured and black-and-white copies. They contain 4 different toner colours, sometimes referred to as the CMYK colour spectrum, and can reproduce almost any combination of colours. CMYK photocopiers are generally bigger and are more expensive than their counterparts. However, a colour photocopier can produce a rainbow of colours.
The most common feature of a photocopier is its ability to create large volumes of copies in a short time. The toner and electrostatic charge used in a photocopier affects the quality of the image. They will not stick to each other and will not smear when compared to a printer. However, this depends on the make and model of the machine. For high-volume copying, photocopiers are more efficient than printers.
As technology advances, more functions are included in photocopiers. Analogue photocopiers use lenses, lights, and mirrors to reflect the image onto the photo receptor. These machines can sometimes experience technical problems, and support for them is scarce. Desktop photocopiers can only produce A4 copies, but you can upgrade your photocopier with additional paper trays. This, however, will increase the height of the machine.
The main function of a photocopier is to produce duplicate copies of documents and images. They operate by using xerography technology, which is similar to laser printers, but uses a dry process. It uses electrostatic charges to attract toner particles to the light-sensitive photoreceptor. The toner then transfers to the paper. Using this technique, a photocopy machine can produce high-quality images that are both quick and inexpensive.
