[E]
After the used master is transported to the master eject box, the master is
compressed by the pressure plate.
The pressure plate is driven by an independent dc motor. The pressure plate
motor [A] drive is transmitted to the gear [B] through gears, and the pin [C]
will move the link [D] downward until the lower pressure plate sensor [E] is
actuated. Spring [F] pull down on the pressure plate [G] and the used master
in the master eject box is compressed. The pressure plate will stay remain in
the lower position until the master making process is completed. The
pressure plate motor then start again to return the pressure plate to the
upper position. The motor will stop when the upper pressure plate sensor [H]
is actuated.
The machine will detect a full master box when the full master box sensor [I]
is not actuated when the pressure plate moves downward.
