4. Feeding the Stack
The unit folds the stitched stack of sheets, and then feeds them to the point of delivery. This point is
where the center of the stack (i.e., stapling position), matches the height of the Paper Pushing Plate
and the Paper Folding Roller nip. The stack is moved forward by operating the Paper Positioning Plate.
When the plate is operated, the Guide Plate which has been covering the Paper Folding Rollers, also
moves down so that the Paper Folding Rollers directly face the stack.

5. Folding / Delivering the Stack
The Paper Pushing Plate pushes the center of the stack again to move it in the direction of the Paper
Folding Rollers. In response, the Paper Folding Rollers pick the stack along its center and folds it in
two. The Paper Folding Rollers together with the Delivery Roller then move the stack along to output it
on the Delivery Tray.
