Figure 1:
The grip assembly consists of the gripper guide bracket [A], the gripper
assembly [B], and the bin side plate [C]. The major components of the
gripper assembly are the grip motor [D] (a stepper motor), dual cam plate
[E], grip home position sensor [F], grippers [G], and grip cam follower [H].
When the copier main switch is turned on, the grip motor rotates forward
and/or reverses to position the whole gripper assembly at the home position.
The home position is detected by the grip home position sensor and the
sensor actuator on the dual cam plate.
Figure 2:
When the bin lift motor stops during the automatic or manual stapling cycle,
the grip motor starts rotating. As the dual cam plate turns counter-clockwise,
the cam groove [I] and the pin [J] on the gripper guide bracket move the
whole gripper assembly along the gripper guide rod [K] into the bin.
Figure 3:
When the high lobe of the grip cam [L] (the small cam on the dual cam plate)
pushes up the grip cam follower, the grippers close to grip the copies that
are stacked in the bin.
