The Inventor
Chester carlson
Chester Flood Carlson was the inventor of the Photocopier which was born on February 8, 1906 in Seattle, Washington, United States.
His father had TB disease, so he had to work hard to get medical expenses. At the age of 17 his mother died and four years after his mother died Carlson's father followed. This did not discourage Carlson from studying.
He was able to finish his education until college at the California Institute of Technology. After graduating from college, Carlson then worked at an electronics manufacturing company. Chester Carlson began his work as a copyist of patent documents in a patent analysis company, Carlson thought to accelerate his work by making a tool that can print documents repeatedly. He also read various references about printing presses.
Eventually, he discovered the concept of electrophotography, which we now know as the photocopier.
In 1938, Chester Carlson made a small experiment that utilized soot powder (carbon) and light irradiation and moved a piece of writing from one medium to another. He also used a concept called photo-conductivity, a process of changing electrons when exposed to light.
In essence, with this process, the image can be duplicated by the process of changing the electron. Most of the literature says, Carlson's findings create a copying process using electrostatic energy, namely xenography.
The name xenography comes from the Greek, radical xeros (dry) and graphos (writing). Because, in the process does not involve chemical liquids, unlike previous technologies. Through this technique, Chester Carlson has devised a way to overhaul the paradigm of a reworked author of a document, which would later become a process called photocopying. The technique was patented on October 6, 1942.
For several years, Chester Carlson tried to perfect his findings. Although very useful, this electrophotographic machine is not in demand by many people, because the machine is considered not to have a promising future. Chester who managed to make the tool must sell the concept for many years so that the copier can be sold on the market.
To develop his findings Haloid Company then changed the name of the first photocopier electrophotography because it was considered to have less selling value, then proposed the name with the name Xerography. Xerography became commercial after it was adopted by Xerox Corporation.
One of Xerox's early products was the Xerox 914, the first automated coffee photo machine to use the xenography process. It was named Xerox 914 to refer to the machine's ability to copy 9 inches x 14 inches (229 mm x 356 mm) of paper.
Xerox 914, which can copy up to 100 thousand papers per month, was very popular among the people at that time. This product accounts for the company's revenue of up to 60 million US dollars. The company decided to change its name from Haloid to Xerox in 1958. Xerox is the world's leading printer and photo copy machine company.
The product produced by the company, which is now headquartered in Stamford, Connecticut, USA in 2006 and managed to record revenue of 15.9 billion US dollars. The number of employees reached 53,700 people, spread across the world. Chester Carlson died on September 9, 1968, in Rochester, New York, of chronic liver disease.
Thanks to his findings through the photocopier, Chester Carlson has found a way to overhaul the paradigm of a document rewriting author.
Up to now, this process can hardly be abandoned in modern life. With the invention of Chester Carlson, we are now easily, cheaply and quickly to duplicate a document.
