CHAPTER 2 OUTLINE OF OPERATION
5.5.2 Paper Folding
Paper is folded using paper fold rollers and a paper pushing plate.
Almost concurrently with the start of roller rotation, the paper pushing plate starts operat-
ing to push the paper stack into the gap between the paper fold rollers. When the paper
stack is fed about 10 mm with the rotation of the paper fold rollers, the paper pushing plate
returns to the home position. Then, the paper stack is delivered to the bind tray using the
paper fold rollers and bind delivery rollers.
Half the entire surface of each paper fold roller is uncovered excluding the central area
and the area at the left and right ends. The uncovered surface of the upper paper fold roller
comes in touch with the uncovered surface of the lower paper fold roller only at the center
and left and right ends, allowing a paper stack to be fed without causing creases. The other
half of the upper paper fold roller that is covered comes in touch with the other half of the
lower paper fold roller that is also covered, allowing a paper stack to be folded while being
fed.
