The story of the invention of copiers

Chester Floyd Carlson, the inventor of photocopiers, who challenged all the difficulties he faced, went out to work to support his family. As a result of the depression that prevailed in the world at the time, his willpower enabled him to continue his career in more than one company until the invention of one of the most important inventions of mankind: photocopiers.

Xerox profits reached $ 60 million after 12 years of creating the first copier
 

Harsh conditions

Chester was born on February 8, 1906 in the US city of Seattle, but the misfortunes of his family prompted him to work at the age of 14 years.
His father became infected with arthritis and kept him out of work. His mother fell ill with tuberculosis and died. He was only 17 years old.
 However, he insisted on completing his education. He joined the California Institute of Technology in 1930, and earned a bachelor's degree in physics.
After graduating, he worked as a research engineer at Bell Laboratories in New York for a monthly wage of $ 35, but was dismissed months later.
 The poor economic situation in America, as a result of World War II, led him to leave his favorite field, to work in a battery manufacturer.
 Chester was promoted to the position of Director of the Patent Department, and here he embraced the idea of ??creating a better way to copy documents.

The idea of ??working copiers

Chester was initially interested in research and reading in the field of optical conduction, until he came to conceive of how photocopiers work.
I understand that if a photograph or document is displayed on a light-conducting surface, the current will flow only to the places where the light has fallen.
The places of printing are dark, emitting no light, and Chester called it "Electro-photography."
Chester succeeded in obtaining a patent in 1937, and presented his idea to more than 20 companies, including: IBM and Kodak.

The first production line for photocopiers

Chester reached out to officials of the Patel Memorial Institute for Technology Research, which he invented, and entered into a partnership agreement.
Under the agreement, Chester granted 40% of the proceeds, and in 1947, Patel signed a licensing agreement with Haloid, a photographic products company.
The first photocopiers were introduced in 1949, under the name Xerography, and bore the first Xerox model.
Haloid changed its name twice: the first in 1958, where it became Haloid Xerox, and the second in 1961, and became the name Xerox.

The development of copiers

The success of Xerox in promoting its products was not easy, as it did not taste the success until the launch of the model 914.
 The success was due to the machine's handling of sheets in sizes up to 9 by 14 inches, and because of that the company's revenues rose to 60 million dollars in 1961.
Xerox has sought to develop its products through four research centers for the development of photographic, printing, copying and scanning technologies.
In the 1980s, Xerox was able to produce color copiers, and in the 1990s it was followed by the latest digital technologies.
 With continuous development, photocopiers have become a compact laser printer with a scanner, coupled with other possibilities such as improved image quality and automatic digital ordering.
