position. The stack gripped in this way by the paper folding roller is drawn further by the paper folding roller and
then is moved by the delivery roller to the paper tray.
The thickness of the paper folding rollers is reduced at a half of their periphery except the center area.
At the other half of the periphery, where the thickness is not reduced, the paper folding roller (upper) and the paper
folding roller (lower) contact each other tightly, and paper starts to be folded at this position. The upper and lower
rollers feed paper while folding it. Also, these rollers stop at this position.
At the half periphery where the thickness is reduced, the paper folding roller (upper) and the paper folding roller
(lower) do not contact each other except at the center, so they only feed paper to prevent paper from being wrinkled.
The paper folding start position and stop position of the paper folding rollers are controlled by the number of motor
pulses delivered from the paper foldimg home position sensor (P121).
