Copying machines, commonly known as copiers, are devices used to produce duplicate copies of documents and images. They work by scanning the original document and then printing it onto paper, allowing for quick and efficient reproduction. Modern copiers can handle various paper sizes and types, making them versatile for different copying needs. Many copying machines also include additional features such as faxing, scanning, and printing capabilities, often referred to as multifunction printers (MFPs). These machines are widely used in offices, schools, and homes, streamlining the process of document management and distribution.
