2.3.4 PRESSURE PLATE MECHANISM
The pressure plate motor [A] drives the pressure plate through the drive arm [B]
and the pressure springs [C].
When the master has been ejected into the master eject box, the pressure plate
motor turns until the actuator on the pressure plate [E] actuates the pressure plate
limit sensor [D]. When the limit sensor is actuated, the motor stops. When master
making and cutting are completed, the motor turns in the reverse direction to return
the pressure plate to the home position. When the pressure plate home position
sensor [F] is actuated, the motor stops.
If the pressure plate limit sensor is not actuated within 2.8 seconds after the
pressure plate motor is activated, the machine determines that the eject box is full
and that the pressure plate cannot travel any more. In this case, the machine
determines that the complete master has been fed into the box and stops the
motor (after returning the pressure plate to the home position). The Empty Master
Eject Box indicator lights when the drum returns to the home position at the end of
the next master making process.
