A manual document feeder is a device found in printers and copiers that allows users to input single sheets of paper for scanning or printing. Unlike automatic feeders, which can handle multiple pages at once, manual feeders require users to place each sheet individually. This feature is useful for handling special media types, such as envelopes or thicker paper. These feeders are typically located at the front or top of the machine and are designed for easy access. Users can simply lift the feeder, insert the document, and initiate the printing or scanning process. Manual document feeders are common in both home and office settings, providing flexibility for various printing tasks.
