A Document Feeder is a device commonly found in printers and scanners that automatically feeds multiple sheets of paper into the machine. This feature allows users to scan, copy, or print several documents without having to place each sheet manually. It enhances efficiency, especially in office settings where large volumes of paperwork are handled. There are two main types of document feeders: Flatbed and Automatic Document Feeders (ADF). ADFs can handle double-sided documents and often include features like duplex scanning. This makes them ideal for tasks that require quick processing of multi-page documents, saving time and effort for users.
