Paper Separation
It also drives the pick-up roller [E] because the pick-up roller is linked to the feed roller by an idle gear. When the paper feed station is set in the mainframe, the separation lift lever rises. As a result, the separation roller [A] contacts the paper feed roller [D] and turns with the feed roller, unless more than one sheet of paper is fed.Web
