11. The duplex gate is moved into position by a solenoid. After passing through the gate, the paper reaches the
paper pass sensor. The paper pass sensor performs two tasks. It can determine whether a jam has taken place.
The jam is triggered by the time it takes for the paper to pass through the sensor. The sensor also determines
the position of the paper in the ADF paper path. Based on the size of the paper in the scan job, the sensor
determines that the paper has left the ADF paper path. At this point, a signal is generated to trip the duplex gate,
moving it to the position allowing the paper to enter the duplex paper path. Also, a signal is generated triggering
the gear solenoid. The gear solenoid moves the reversing gear assembly into place, reversing the direction of
the duplex paper rolls. This creates the peek a boo effect, pulling the paper into the duplex paper path. If the
scan job is simplex, the duplex gate is positioned to direct the media to the exit roller and the media exits the
ADF to the output bin.
12. The reversed exit roll pulls the paper back into the ADF. The transport roll then moves the media to the
paper in sensor. When the paper in sensor is actuated, the exit roll stops. Also, the paper in sensor indicates
that this is the second side of the media to be scanned.
13. The imaging process is repeated for the other side of the sheet of paper. After the image is created, the
paper again proceeds to the paper pass sensor a second time
14. When the trailing edge of the media reaches the reverse point the second time, the solenoid again moves
the diverter gate to the down position and reverses the exit roll. The paper goes back into the ADF unit for a third
time. The paper passes through the paper path, but no imaging occurs. This pass is to turn the paper over to the
original side up. On the third pass of the media trailing edge over the reverse point, the solenoid is not actuated.
The paper proceeds to the exit rolls and passes out of the ADF to the exit bin.
