Double Folding a Stack
To fold a stack consisting of 10 or more A4R or LTR-R sheets, folding is executed twice for the
same stack.
The folding rollers rotate in reverse for an equivalent of 20 mm after gripping the stack for a
length of 20 mm, enabling the folding rollers to apply an increased degree of pressure along the
crease on the stack. Then, the folding rollers rotate normally, and the paper pushing plate returns to
home position while the stack is being delivered.
This way, a stack requiring a large force may properly be folded with less pressure.
