The office photocopier uses a process called xerography, a term that derives from the ancient Greek words meaning “dry writing.” Powered by an electric type of photography – Copier Repair Pros.
At the heart of the photocopier is a metal rotating drum coated with a material that conducts electricity when light hits it. When it is dark, the drum rotates against a alambrito leading high-voltage electric charge, allowing the drum is charged with static electricity. A bright light illuminates the document to be copied and mirror projects this image. When the document is blank printing paper without light strikes the drum and remove the static charge.
The drum is loaded in the areas corresponding to black parts in the original, where light does not reach. A black fine powder called toner , which leads the opposite electric charge is attracted to the charged areas of the drum, and then transferred to a sheet of paper on which melts through a heated roller. Some of this heat can be felt at the time the copy exits the machine.
The copy machine was patented in 1938 and the American company Xerox marketed it in 1947, its use was popularized in the 1960s. The modern copiers can copy documents as continuous-tone photographs, color copying, copying on both sides of the paper and enlarge or reduce copies Copier Repair Pros.
