Canon's goal was to create better xerographic technology, inkjets being just one of several options.
This xerographic leviathan can handle runs of up to 7m colour pages a month.
Amorphous selenium (Se) and, later, amorphous arsenic selenide (As2Se3) were used to form the thin-film, large-area photoconducting element that lies at the heart of the xerographic process.
Throughout the world in offices, libraries, schools, and so forth the xerographic process makes more than five billion copies every day.
This important amorphous semiconductor is also used as the image sensor in facsimile ("fax") machines, and it serves as the photoreceptor in some xerographic copiers.
Electrostatic (or xerographic) transfer plates were developed from the principle that certain materials (such as selenium) that are insulators while in the dark become conductors of electricity when exposed to light.
Xerox Corporation, major American corporation that was the first manufacturer of xerographic plain-paper copiers.
In 1947 the firm obtained the commercial rights to xerography, an imaging process invented by Chester Carlson (see also electrophotography). Renamed the Haloid Xerox Company in 1958, the company introduced the 914 xerographic copier in 1959.
Notably, he constructed a huge electrophorus and, in the course of experimentations, discovered in 1777 the basic principle of modern xerographic copying; the images that he reproduced are still called "Lichtenberg figures".
In xerographic printers, she continued — she had to shout above the press's vacuum pumps, which sound like a copier's, but louder — "the sheets are charged with sixty-five hundred volts.
Today, not all Xerox printers are xerographic; many are ink-jets, which work by converting an image into a waveform, then using the waveform to control an ink nozzle.
