12.1.2.5.3. Paper Feed System
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, allowing the next step
(stitching and folding) to be performed.
When sheets of paper have been stacked and aligned on the Processing Tray, the Paddle Motor (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 toward 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 motor pulses to stop the center of the paper stack
(stitching position) at the stapler's staple position. 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.
