what is adf in printer

ADF stands for Automatic Document Feeder. It is a feature found in printers, scanners, copiers, and fax machines that allows the user to feed multiple pages into the device and scan, copy, print, or fax them in a single operation. The ADF guides the sheets of paper through a series of rollers and into an exit tray, ensuring that each sheet is fed into the device straight, resulting in an aligned document. The ADF can be adjusted to fit different paper formats in a few simple steps. The ADF is a common feature on most multifunction or all-in-one printers to help relieve people from waiting for a printing job to complete.
