Document feeder duplex operation (standard model)

Following is a description of the second pass of a page during a duplex copy job. The back side of the

page is scanned.

1. The trailing edge of the paper travels a preset distance before pinch-m-duplex activates to pull the

paper back.

2. The deskew motor rotates the deskew drive roller to pull the paper into the prescan drive roller.

3. The feed motor rotates to drive the paper into the prescan sensor. The firmware registers the

leading edge position of the paper as the prescan frontside sensor is activated.

4. The feed motor continues to rotate and drive the leading edge of the paper through the preset

distance from the prescan frontside sensor to the scan zone. The scanner begins the scanning and

data retrieval process.

5. The prescan frontside sensor deactivates when trailing edge of the paper passes the sensor. The

firmware registers the trailing edge of the paper position.

6. The feed motor continues to rotate and drive the trailing edge of the paper through the preset

distance from the prescan frontside sensor to the scan zone. The scanner ends the scanning and

data retrieval process.

7. The trailing edge of the paper travels a preset distance before pinch-m-duplex activates to pull the

paper back.

Document feeder duplex operation (standard model)

Following is a description of the third pass of a page during a duplex copy job. The page is turned

over and then moves to the output bin. This action allows the copy job to maintain the same page order

as the source documents.

1. The deskew motor rotates the deskew drive roller to pull the paper into the prescan drive roller.

2. The feed motor rotates to drive the paper into the prescan frontside sensor.

3. The feed motor continues to rotate and drive the leading edge of the paper through the preset

distance from the prescan frontside sensor to the scan zone.

4. The prescan frontside sensor deactivates when trailing edge of the paper passes the sensor.
