Media Empty Detection
• The media empty sensor (PS10) of the PC control board (PCCB) detects a media empty
condition in the lower feeder unit.
• When there is media loaded in the lower feeder unit, the actuator is raised, which
unblocks the sensor.
• When there is no media, the actuator drops into the slit in the media lift plate, thus block-
ing the sensor.
