4. Double Folding a Stack
To fold a stack consisting of 10 or more A4-R or LTR-R sheets, folding is executed twice for the same
sheet.
The Paper Folding Rollers rotate in reverse for an equivalent of 20 mm after gripping the stack for a
length of 20mm, enabling the Paper Folding Rollers to apply an increased degree of pressure along
the crease on the stack. Then, the Paper Folding Rollers rotate normally, and the Paper Pushing Plate
returns to its home position while the stack is being delivered. This way, a stack requiring a large force
may properly be folded with less pressure.
a. The Paper Pushing Plate pushes the stack in the direction of the Paper Folding Rollers.
