Hi All,

Here is wht I want you all to do:

1) From the printer Setup menu look under "Reports" menu and select the option "Printer Status Report". Once it prints out look for the option "Duplexer". It should say "Installed".

2) In the computer, close all the windows which are open like Word, Acrobat etc
3) Double click the printer icon which you see on the computer screen. Open Printer actions and then open "Customize your Printer"
4) Click on "Device Settings" tab. Here "Two Sided Printing" or "Duplexer" should say "Installed" or Automatic" and if you see "Manual Duplex" this should read "Disabled". Click Apply and click OK
5) Click on "Set your Preferences"
6) Check for the option "Print on both sides" or something like that. For this option select "Flip on Short Edge"
7) Also click on "Advance" button and look for any reference to two sided printing.
8) Click Apply and click OK. Now try printing.

If it resolves your problem, but it prints upside down, from the application Click on File ==> Print ==> Select the printer ==> Click on Properties. Here select "Flip on Long Edge" and then try printing.

Note: Legal size paper cannot be used for duplex printing. Try with Letter size or A4 size paper.
