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 operating
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 roll-
ers 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.
