CHAPTER 2 OUTLINE OF OPERATION
5.3 Paper Feed System
5.3.1 Outline
The paper feed system feeds a stack of sheets (coming from the finisher) to the position
where the center of the paper stack (stitching position) is aligned to the stapler's staple, allow-
ing the next step (stitching and folding) to be performed.
When sheets of paper have been stacked and aligned on the processing tray, the paddle mo-
tor (M2) rotates in the reverse direction, causing the swing guide to descend. As the swing
guide descends, the paper stack is sandwiched between the upper and lower stack delivery
rollers. The delivery motor (M3) rotates in the reverse direction, feeding the paper stack to-
ward the saddle unit. When the leading edge of the paper stack reaches the folding position
sensor (PI10), the finisher controller PCB drives the delivery motor a specified number of mo-
tor pulses to stop the center of the paper stack (stitching position) at the stapler's staple posi-
tion. Before the paper stack passes through the stack feed rollers, the feed motor (M1) is
driven to rotate the stack feed roller (lower) so that the leading edge of the paper stack is not
bent.
