2. Clamp Plate Opening Mechanism

When the START key is pressed for the master-making or confidential-master making, the print drum starts to

rotate from its position-B. After the presence of the master on the print drum is checked and as the print drum

returns to position-B, the print drum stops once and starts the clamp plate opening action. The clamp motor

activates and rotates the clamp cam until the light path of the clamp sensor-B is blocked by the disc. This

action brings the clamp opening cam down.

The print drum then rotates to start the master removal action. The clamp opening cam, at its lowered position,

opens the clamp plate first, and then lifts the master ejection plate to eject the leading edge of the master out

from under the clamp plate.
