When the last paper pickup roll rotates, the slit in the roll cuses the output of the last paper sensor (PS9) to beocme
wave-form pusles. The last paper roll rotates only when the last paper is picked up; otherwise, it remains still. The
machine will identify the paper to be the last paper if it detects 4 or more output pules form the lat paper sensor.
