What is copiers?

Copiers, also known as photocopiers or copy machines, are devices that make paper copies of documents and other visual images quickly and cheaply. They typically use a technology called xerography, which is a dry printing process that uses electrostatic charges on a photoreceptor to attract toner particles, and then transfers the toner to paper via heat and pressure. Copiers are commonly used in offices, schools, libraries, and other settings where document duplication is required.
