Paper empty detection

• The paper empty sensor of the PF drive board detects a paper empty condition in the
lower feeder unit.
• When there is paper loaded in the lower feeder unit, the actuator is raised, which
unblocks the sensor.
• When there is no paper, the actuator drops into the slit in the paper lift plate, thus block-
ing the sensor.
