KX-P7100
4.4.15.3. Exit Sensor Circuit
Exit sensor detects that the media is at the rear of the Fuser Roller ( Exit of the printer ). When the exit sensor detects the media,
nEXITSEN signal changes from high level to low level. +5VSP is the power of the photo sensors. When the5VCTL signal at pin32
of IC11 ( CPU ) is low level, the transistor Q13 is turned on. This supplies +5V power to the photo sensors.
