Detailed explanation-1: -Also known as a copier or copy machine, a photocopier makes paper copies of documents. Most photocopiers use xerography, a dry printing process in which electrostatic charges are used to transfer toner onto paper in the same position as the original document, which is then bonded into place using heat and/or pressure.

Detailed explanation-2: -After consulting a professor of classical language at Ohio State University, Haloid and Carlson changed the name of the process to “xerography”, which was derived from Greek words that meant “dry writing”. Haloid called the new copier machines “Xerox Machines” and, in 1948, the word “Xerox” was trademarked.
