Paper Separator Mechanism - Riso RZ3xx Series Technical Manual

2. Paper Separator Mechanism

The tip of the separator is positioned close to the print drum surface when separating the paper from the print
drum. As the print drum rotates and the clamp plate base approaches the separator, the cam follower on the
separator lever assembly rides on the high part of the main gear. The high part of the main gear pushes the
separator lever assembly down. This action rotates the separator shaft and brings the tip of the separator
down, away from the print drum to clear the clamp plate base on the print drum.
During the removal and insertion of the print drum into the machine, the tip of the separator needs to move
away from the print drum to prevent being hit by the print drum. A plastic release arm attached on the slide
rail pushes the release lever and rotates the separator shaft to move the tip of the separator down, away from
the print drum during the print drum removal and insertion.
