Fig. 7-3-14
The paper empty detect circuit consists of the I/OP-2 GA (IC48) and other peripheral devices.
It detects the presence or absence of recording paper in the recording paper tray through the
paper empty sensor connected to CN15 on the Mother PBA.
When recording paper is present, the actuator of the paper empty sensor is pushed down by
the recording paper to turn on the sensor. This causes the PE signal to be LOW and input to
the I/OP-2 GA to detect the presence of recording paper.
