The duplex printing feature of this machine adopts the Paper Exit/Reverse/Duplex method, whereby switching of the Duplex Junction Pawl and forward reverse control of the Paper Exit/Reverse Roller allow the sheet to Switch Back.
In duplex printing, the front end of the sheet with the first side printed is pulled into the Paper Exit/Reverse Roller when the Duplex Junction Pawl is switched, and the Paper Exit/Reverse Roller rotates in the reverse direction. After the rear end of the sheet passes through the Paper Exit Sensor, the Duplex Junction Pawl returns to its original position before the sheet is completely discharged and the rotation direction of the Paper Exit/Reverse Roller switches back to normal. The sheet is then sent to the Duplex Transport path.
Next, after the second side is printed, the sheet printed on two sides is discharged into the Paper Exit Tray.
