ADF feed system

The ADF has built-in duplexing capability for scanning two-sided documents. Pages from the original document enter the ADF from the ADF input tray. A separation roller and separation pad work together to separate the top sheet from the stack. The page passes through a set of registration rollers and two sets of feed rollers that advance the page. A set of delivery rollers delivers the page to the ADF output bin. A bin-full sensor detects when the ADF output bin is full and stops the feed mechanism until the bin is emptied.
