Clamp Plate Master Clamp Mechanism - Riso RZ3xx Series Technical Manual

4. Clamp Plate Master Clamp Mechanism

Once the load pulse motor on the master-making area feeds a set length of the master material onto the print
drum, the clamp motor activates to rotate the clamp cam until the light path of the clamp sensor-A is blocked
by the disc and the light path of the clamp sensor-B becomes unblocked. This action brings the clamp
opening cam up and closes both the master ejection plate and the clamp plate to clamp the master material
under the clamp plate. At this stage both the clamp opening cam and position-A compensation plate are
brought up back to their home position.
