MECHANISM
1. Clamp Unit Home Position Movement
Clamp open arm and Master release arm positions of the Clamp unit are checked by the Clamp
sensor to see if they are in home position every time the machine power is turned ON or the START
button is pressed for confidential or normal master making.
The Clamp unit is at its home position when the light path of the Clamp sensor is blocked.
If the light path of the sensor is open, the Clamp motor is activate to move the arms until the light path
of the sensor becomes blocked.
2. Clamp Plate Master Release Movement
When the START button is pressed for confidential or regular master making, the Drum rotates to
Position-A.
The Clamp open arm comes down first and opens the Clamp plate to free the leading edge of the
master. Next, the Master release arm comes down and raises the Master release bar to push the
leading edge of the master out of the Clamp plate.
The Clamp motor continues to rotate the Clamp cam assembly until both the Clamp open arm and
Master release arm are lifted to close the Clamp plate and Master release bar. The master release
movement is completed when the light path of the Clamp sensor becomes blocked and the Clamp
motor stops.
