■ Level Sensor
The Level Sensor uses an actuator to determine whether paper in the tray is lifted
to the optimum feeding position. When the flag of the actuator leaves the sensing
area, the sensor detects that the paper has been lifted.
■ Feed-Out Sensor
The Feed-Out Sensor detects a paper jam in the tray by the paper position and
sensor transition time.
■ No Paper Sensor
The No Paper Sensor uses an actuator to determine whether the tray is empty.
When the actuator lowers, the No Paper Sensor signal goes High indicating an
empty tray.
■ Feeder Board
The Feeder Board communicates sensor information to the Motor Driver Board.

Paper Support that rotates 180 degrees to support the stack, and a latching door for
