Did you ever get this sorted?
I have same issue using the top auto loader. If you put your original on the glass it will prompt you to turn it over and rescan - then print. A rather useless way to make double sided copies IMHO.

It is possible that the other user has the MF634Cdw, which is why the 2-sided to 2-sided option was available. The MF632Cdw and MF731Cdw support manually copying 2-sided documents only from the platen. The document feeder does not support automatic duplex scanning. Please view more at the link below:
Regarding not being able to see the option for Copy in initialization menu, Copy is located under [Function Settings], so you will need to select this option if you do not see the 1-sided to 2-sided option.
