How do I correct odd page upside down while duplex printing?

Question

My MX870 prints every other page upside down while printing a catalog in duplex mode.  How can I correct this? The catalog was written using MSWord 2007. Obviously, I can manually duplex the catalog. I am praying there is a solution to be able to automatically duplex.
Thank you.

After 3 days of futile efforts to solve odd page upside printing in duplex print. The problem was solved as follows:
Go to the print menu
1. Go to quick setup
select "Preview - Duplex - Paper size - Orientation [make sure document and printer orientation are the same}
2. select "page setup "
on page layout select "normal size print" - "duplex automatic" - "stapling left side"
Print area setup  "select - used reduced printing"       Selection of " use reduced printing" is the key to solving the problem
3.  Problem solved
