PAPER FEED SECTION

[2] Mechanisms
1. Paper Feed Drive Section
The drive section performs the following kinds of control
when originals are being fed.
a. Original push pressure plate pressing and release
operations
The drive force from the push pressure motor (M304) is
transferred to the swing lever via the lifting cam.
The swing lever is mounted on the original push pressure
plate. The drive force from the swing lever causes the
original push pressure plate to move up and down. As a
result, the original push pressure plate alternately pushes
against and separates from the original in the original paper
feed tray. The push pressure spring maintains the paper
feed pressure constant.
