3.6 GRIP ASSEMBLY
The grip assembly consists of the grip motor [A], the timing belt [B], the drive
gear [C], the grip home position sensor [D], and the cam gear [E].
The grip motor drives the cam gear through the timing belt and drive gear.
Cam gear rotation drives the mechanism that catches the copies and moves
the grip arm unit [F]. When the cam gear rotates clockwise one full turn, the
grip arm moves to catch the copies and returns to the home position to
prepare for stapling. After stapling, the cam gear rotates counterclockwise
once so that the stapled copies go back to the bin, and the cam gear returns
to its home position.
When the cam pushes the roller [G] on the lever [H] and the lever pushes the
grip arm, the grip arm can catch the copies.
A pin [I] on the cam gear fits into the slot in the grip arm unit. So, when the
cam gear rotates, the slot moves the grip arm unit inward and outward.
The actuator [J] on the cam gear activates the grip home position sensor
once every rotation of the cam gear. This allows the sorter stapler to
determine that the cam gear has rotated once.
