Flood Chester Carlson inventor of a photocopy machine was born on February 8, 1906 in Seattle, Washington, USA father contracted tuberculosis forced him to work hard to get the cost of treatment. By the time 17-year-old mother died, and four years after his mother died following Carlson's father. This does not make Carlson discouraged to learn. He could finish his education up to the college at the California Institute of Technology. after completing his studies, Carlson and then worked at a manufacturer of electronic goods. Chester Carlson began her work as a copyist in a patent document peruahaan patent analysis, Carlson thought to accelerate job is to create a tool that can print documents repeatedly. He also read the various references to the printing press. Finally, he found the concept of electrophotographic, which we now know as a copier.
In 1938, Chester Carlson made a small experiment that utilizes powder soot (carbon) and light exposure and move a post from a medium to another medium. He also uses a concept called photo-conductivity, an electron change when exposed to the light. In essence, with this process, the image can be coupled with process changes the electron. Most of the available literature, the findings of Carlson creates a copy process using electrostatic energy, ie xenography.
Xenography name comes from the Greek, radical Xeros (dry) and graphos (write). Because, in the process does not involve chemicals, unlike previous technology. Through this technique, Chester Carlson has found ways remodel paradigm replicates author a document, which later would be called the photocopying process. This technique is then patented in October 6, 1942. For several years, Chester Carlson trying to perfect his invention. Although very useful, electrophotographic machine is not
interest many people, because the machine is considered to have a promising future. Chester who managed to make a tool that must sell the concept for many years that the copier can be sold on the market. Large companies like Kodak is selling the equipment and the process of shooting, IBM and General Electric, rejected the findings. After almost desperate, Chester got the first Batelle Memorial Institute partners who are willing to capitalize the fund and then with the same effort and managed to persuade Haloid, a medium-sized company Haloid Corporation, New York that sells photo paper would be its partner to develop its findings later changed the name Haloid Company The first electrophotographic copying machines because they lack commercial value, then been proposed name with the name of xerography. Xerography became commercial after adopted by Xerox Corporation.
One of the initial product is a Xerox Xerox 914, the first automatic copier that uses xenography process. Named Xerox 914 to refer to the ability of the machine to copy paper with a size of 9 inches x 14 inches (229 mm x 356 mm). Xerox 914, which can copy up to 100 thousand papers per month, is very popular among people at that time. This product revenues accounted for up to 60 million U.S. dollars. The success made the company decided to change its name from Haloid became Xerox in 1958. Until now the company Xerox is a copier and printer in the world.
The resulting product companies are now headquartered in Stamford, Connecticut, USA in 2006 and recorded a 15.9 billion U.S. dollar revenue. The number of employees reached 53,700 people, spread across the world. Chester Carlson died on 9 September 1968, in Rochester, New York, due to chronic liver disease. Thanks to its findings through a copy machine, Chester Carlson has found ways remodel paradigm replicates a document writer. Until now, this process can hardly be left in modern life. By Chester Carlson's invention also present us with an easy, cheap and quick to duplicate a document.
