Main Functional Cycles of the Stapler (Internal Paper Path) Figure 5-27 Stapler Cycles Paper Feed Cycle The stapler bed assembly receives the paper from the 8-bin Mailbox/ 5-bin Mailbox with Stapler Head assembly. The IR Sensor detects when the paper arrives in the stapler. The Retainer (a shaft holding two rubber flexible fingers or anti-curl fingers) rotates once to apply pressure down and backward. This action forces the paper to register against the rear wall of the stapler bed, as well as reduces paper curl. The Registration Pusher (located in the right side of the Top Assembly) registers the paper against the left wall of the stapler bed.
This cycle is repeated until the amount of sheets to be stapled is reached (with a maximum of 20). C4085-91087 Paper Paths and Components 141
