2-1-1 Mechanical construction
The side feeder consists of the paper lifting mechanism, which winds up paper with the wire of the side feeder lift motor
(SFLM), and the paper feed and conveying mechanism, which conveys paper with the drive of the paper conveying belt,
feed roller and left feed roller.
The side feeder lift motor (SFLM) raises the lift by winding up the wire engaged with the pulley. The lift is stopped at the
upper and lower limit by the control of the upper limit detection switch (ULPSW) and lower limit detection switch (LLPSW).
Paper is fed by controlling currents of air. The top sheet of the paper loaded on the lift is floated by the separation fan
motor (SPFM) and then induced onto the paper conveying belt by the suction fan motor (IFM). The sheet thus attracted to
the paper conveying belt is then conveyed to the feed roller and left feed roller by the drive of the side feeder drive motor
(SFDM).
