Hello,
We would be happy to assist, but we would need some additional information to assist further. You can reply to this message with the information below and we can provide some troubleshooting steps or suggestions. For a more immediate resolution I would suggest contacting support over the phone at 1-800-652-2666. Our agents would be happy to assist, and they can check the driver/program settings that you are using that might be causing the issue.
1. What size and type of paper are you trying to print on?
2. What program are you printing from?
3. When it does not duplex print, do you get an error or what happens?
