Canon Multifunction Photocopier Machine

The photocopiers primary function is to produce paper copies of a document. Most modern photocopiers use laser technology to do this, using electrical charges to transfer toner to a piece of paper to form an image.Photocopiers work on the principle that 'opposites attract'. Toner is a powder that is used to create the printed text and images on paper. The powder is negatively charged, and so it is attracted to something positive – the paper.Principal photocopying processes include silver halide, transfer, plan, thermographic (see thermography), and electrostatic (e.g., xerography, which has become so widespread that the process is popularly almost synonymous with photocopying).
