For autoduplexing, make sure that you 
have a duplex option installed.

Make sure that you are using correct 
media. 

" Only Letter/A4 plain paper can be 

autoduplexed.

" Do not duplex labels, postcards, 

thick stock, letterheads, or plain 
paper with a size other than Letter/
A4.

" Make sure that you have not mixed 

media types in Tray 1.

Make sure the duplex option is installed 
and declared in the Windows printer 
driver (Properties/Configure tab).
