Booklet-making
Paper-fold rollers and the paper-pushing plate fold paper in the multifunction finisher. When the
rollers start to rotate, the paper-pushing plate pushes the paper stack into the gap between the
paper-fold rollers. When the paper stack is fed approximately 10 mm (0.4 inch) by the rotation of
the paper-fold rollers, the paper-pushing plate returns to the home position. The paper-fold
rollers and booklet-delivery rollers deliver the paper stack to the booklet tray.
Half of each paper-fold roller is uncovered (the center and the left and right ends are covered).
The upper paper-fold roller touches the lower paper-fold roller at the center and at both ends to
feed a paper stack without creating creases. The covered portion of the upper paper-fold roller
touches the covered portion of the lower paper-fold roller, allowing a paper stack to be folded
while being fed.
