Originals placed in the feeder are automatically fed sheet by sheet to the scanning area. The feeder also automatically turns over two-sided originals to make one- or two-sided copies.
Canon ADF DADF-AY1An automatic document feeder (ADF) may be a mechanism found on devices like printers, fax machines, photocopiers, and scanners that feeds multiple sheets of paper into a scanner or copier to repeat, print, or fax multipage documents during a single operation. An ADF may be a common feature on most multifunction or all-in-one printers to assist relieve people from expecting a printing job to finish.
Mechanically, Canon ADF DADF-AY1 operates by guiding a sheet of paper through a series of rollers and into an exit tray. for instance, on a scanner, rollers guide a sheet over the scanner flatbed or platen to capture the image and send it to your PC. For a printer, on the opposite hand, an ADF guides paper to the printing heads to supply a physical document.
However, some ADFs are more advanced. They scan each side of a document or process more documents in a fraction of the time. A reversing automatic document feeder (RADF), for instance, feeds a document through a scanner’s platen, flips it, and feeds it through the scanner again to urge a replica of each side of any sheet of paper.
