To use the optional duplex printing accessory:

●Be sure that the optional duplex printing accessory is installed correctly. If the 500-sheet paper feeder (Tray 3) is installed, the duplex unit must be positioned between the printer and Tray 3.

●Verify that the printer driver is configured to recognize the duplex printing accessory. (For instructions, see the online Help for the printer driver.)

●Close the door to the rear output bin. The rear output bin is located at the back of the printer.

●Select the appropriate duplex options in the printer driver software. Duplex options include the page and binding orientation.

●Duplex printing is not supported for certain media types, including transparencies, labels, and cardstock.
