Paper End Detect Circuit
Fig.7-30
The paper end detect circuit consists of the Engine-CPU (IC37) as the central component. It detects the
presence or absence of recording paper placed in the recording paper tray and bypass tray through the
paper end sensor connected to CN21.
When recording paper is loaded in the machine, the actuator of the paper end sensor is pushed down
by the recording paper to turn on the sensor. This causes the MP_PAPER_EMPX signal to go LOW
and input to the Engine-CPU to detect the presence of recording paper.
