3.5 PRESSURE PLATE UP/DOWN MECHANISM

[F]

[I]
[E]
After the used master is transported into the master eject box, the master is
then 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]
moves the link [D] down until the lower pressure plate sensor [E] is actuated.
The spring [F] will pull down on the pressure plate [G] and the ejected master
in the master eject box is compressed. Then, the pressure plate motor will
remain off until the master making process is completed. Then, the pressure
plate motor will 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 that the master box is full if the full master box
sensor [I] is not actuated during the downward motion of the pressure plate.
