A patent lawyer and amateur inventor successfully produced the first xerographic image in a simple laboratory in astoria, Queens, new york on 1938 10/22. He spent several years trying to sell the invention patent, but failed. At that time, company managers and entrepreneurs did not believe that there would be any market for photocopiers with carbon paper, and the prototype products of photocopiers at that time were so cumbersome and ugly. At that time, about 20 companies, including IBM and General Electric, rejected the invention with what Carlson called "no interest". Finally, in 1944, the Bater Institute in Ohio signed a contract with Carlson to help him improve this invention which he called "electrophotography". Three years later, a Harold company in Rochester, new york, found Bater and bought a license to develop and sell the copier invented by Carlson. Harold Company later obtained all the patents of Carlson's invention. Both Carlson and Harold think that the term "electronic image reproduction technology" is too obscure.
So they accepted the suggestion of a classical language professor at Ohio State University and changed it to "xerography", which comes from the Greek roots of "stem" and "writing". Harold Company created another word "Xerox" as the trademark of the new copier. 1948 introduced the words "xerography" (used to describe the copying process) and "Xerox" (logo product) at the same time. After tasting the success of Xerox, Harold Company changed its name to "Harold Xerox Company" on 1958. 196 1 year, when the world accepted the first fully automatic office copier using plain paper-Xerox 9 14 copier, the company was renamed Xerox Company again.
September 1999 is the 40th anniversary celebration of Xerox 9 14 (named after the paper it uses is 9x 14 inch). From 1959 to 1976, Xerox has produced more than 200,000 photocopiers of this model. 1985, 9 14 copier has been launched for 26 years, and Xerox announced that it will not renew the full warranty maintenance contract of 9 14 copier. For the 6,000 9 14 machines still in operation, Xerox will adopt the maintenance service mode of charging materials and labor separately. Today, the Xerox 9 14 copier has become an exhibit of the Smithsonian Museum and a part of American history. In some parts of the world, 9 14 machines are still used in customers' companies. In South America, Xerox is still maintaining several 9 14 photocopiers.
