The photocopier was invented to make quick and easy copies of documents without the need for manual transcription or duplication. It revolutionized office work by streamlining the process of reproducing documents and sharing information. The first photocopier was developed by Chester Carlson in the early 20th century.
brazil invented the first photocopier machine
To make copies of documents and pictures.
Photocopiers replaced several less-versatile machines, including the mimeograph, a nasty monster that used a typed template on a drum. Ink inside the drum flowed out through openings made by the typewriter, and onto paper as the drum rotated over it. Those of us who used them were very happy to see the first photocopiers, believe me.
James Watt did not invent the photocopier. He was a Scottish engineer and inventor known for his work on the steam engine. The photocopier was actually invented by Chester Carlson in 1938.
by hand
The process of xerography upon which the photocopier is based was first successfully demonstrated by Chester F. Carlson in Astoria, Queens, New York City on 22 October 1938. He was seeking a better means of reproducing drawings for use in patent applications, which until that time had to be reproduced by hand or through a costly and time consuming photographic process. It was another 20 years before the first fully automated photocopier was offered for sale by the Xerox Corporation of Rochester, NY.
