A photocopier (also known as copy machine or copier) was first introduced by Xerox in 1959. It is a machine that produces paper copies of text documents, photos, or illustrations. Most modern photocopiers use a technology called xerography, a method that uses electrostatic charges on a light sensitive photoreceptor to attract and lay down toner to paper. Heat, pressure or both are then used to meld the toner onto the paper creating a visible image.


Copiers can use inkjet technology too but xerography is standard for businesses due to its reduced cost.


Users in a small office or home should use a scanner or All-in-One printer to make copies of documents. This option is much less expensive and more compact than a traditional photocopier.
