2.10 MOVING THE STACK TO THE FOLDING POSITION
First, the upper clamp roller feeds the stack down after the stack has been stapled. When
the lower clamp roller [A] catches the stack, the upper clamp roller stops, and the lower
clamp roller feeds the stack down.
The lower clamp roller is released just before the leading edge of the stack reaches the
bottom fence [B] (this fence consists of two pawls that catch the paper). The bottom fence
moves the stack to the folding position
The fold roller motor [C] turns the lower clamp roller.
The lower retracting motor [D] moves the lower clamp roller against and away from the
stack. The lower clamp roller HP sensor [E] detects when the lower clamp roller is moved to
the home position.
The bottom fence lift motor [F] moves the bottom fence up and down. The bottom fence HP
sensor [G] detects when the bottom fence is at home position.
