Located below the bottom plate of the paper cassette in
Tray 2 (the optional paper feed unit). A spring loaded
bottom plate keeps the top of the stack against the
pick-up roller for paper feed. A free-swinging feeler
rests on top of the stack. After the last sheet feeds, one
end of the feeler falls down through a cutout in the
bottom plate. An actuator on the other end of the feeler
swings up and out of the gap in the paper end sensor.
This signals paper end.
Located below the transport belt. A spring loaded
bottom plate keeps the top of the stack against the
pick-up roller for paper feed. A free-swinging feeler
rests on top of the stack. After the last sheet feeds, one
end of the feeler falls down through a cutout in the
bottom plate. An actuator on the other end of the feeler
swings up and out of the gap in the paper end sensor.
This signals paper end.
Located inside the printer near the transport belt. The
temperature/humidity sensor constantly measures
temperature and humidity around the transport belt.
The printer uses these readings to adjust the amount of
charge applied to the areas of the belt that contact the
leading edge, center, and trailing edge of the paper. For
more, please refer to Section "4. Troubleshooting."
