Copier inventor Chester Carlson (ChesterCarlson, also translated Chester Carlson), originally a patent attorney, a part-time researcher and inventor. He needs to copy large amounts of important paperwork New York patent office. Carlson suffering from arthritis, depending on copying files to the pain and monotonous work. This has encouraged him concerning Photoconductivity experiments, and estimates can most easily make copies. Karl fast in the kitchen at home Electrophotography experiment conducted in 1938 to patent process technology. He used to cover the zinc sheet sulfur to produce a copy of the initial product. He used a zinc plate covered with sulfur made the first "Copier." Text "10-22-38Astoria" printed on a microscopic slide, the slide on the sulfur carry out glare. After the slide away, those words mirrored on the left on the sulfur. Carlson intends to sell his invention to some companies, but because this process is not mature so failed to achieve results. Copier principle copier principle in that era, a lot of duplication of work using carbon paper or copy machine to complete, there is no strong demand for electronic photocopiers. In 1939 and 1944, Carlson was more than 20 companies, including IBM and General Electric, including denial, no one believes there will be a lot of copier market demand. In 1944, a non-profit organization based in Columbus, Ohio, contracted with Carlson to refine his new process. In the subsequent five years, the agency carried out many experiments to improve the electrophotographic process. In 1947, Haloid (a New York-based manufacture and sale of paper was a small organization) approached Battelle to obtain a mandate to develop and sell the technology-based copier. Haloid realized that "electrophotography" the word is too complicated and not very good memory. After consultation with a professor of classical languages ??at Ohio State University, Haloid and Carlson will change the name of the process to "Xerography", which consists of Greek "dry writing" is derived from the word. Haloid decided a new copier called "Xerox" In the selection process be sure to choose a high-quality copy printer.
