A photocopier (otherwise called a copier or copier) is a machine that makes duplicates of reports and other visual pictures onto paper or plastic film rapidly and efficiently. Most current scanners utilize an innovation called xerography, a dry procedure that utilizes electrostatic charges on a light-touchy photoreceptor to initially pull in and afterward move toner particles (a powder) onto paper as a picture. Warmth, pressure or a blend of both is then used to intertwine the toner onto the paper. Copiers can likewise utilize different advances, for example, ink stream, however xerography is standard for office duplicating.

Photocopying is generally utilized in the business, training, and government parts. While there have been forecasts that printers will in the end become out of date as data laborers increment their utilization of advanced record creation, stockpiling and conveyance, and depend less on dispersing real bits of paper, starting at 2015, scanners keep on being generally utilized.
