The feeder assembly contains a mechanism to feed paper picked up from the cassette into the printing
device. When the paper feeder is the paper source, paper is passed on through the vertical paper feeder
assembly, then the feeding roller and feeding roller as they rotate, finally to the main device. The multiple feed
sensor is provided to detect more than one sheet of paper are fed at one time. The SM diverging solenoid
then activates the diverging guide so that the excessive sheet(s) of paper is diverged and set aside by means
of the ejection rollers as they rotate into the ejection tray.
