Last paper detection is performed so as not to form images within the ITB when the paper is out. Only when feeding the last paper, the last paper roller [1] rotates.
The rotation of the last paper roller [1] induces the output of the pulse signal from the last paper sensor (PS10) by the slits on the roller. When 4 output pulses or
more were detected, the paper is determined as the last one.
