I don't understand why you don't have those options on a 3225. You get free service for a year after purchase so you can call it in.
Per the 3225 User Guide:
I've had this printer less than a week... I printed a packet that had double sided pages, 1 double sided page printed with characters not letters. I printed just that page & it printed fine- I needed more copies of that page so I put the paper in the feeder to copy but only it printed 2 pages not double sided. It is set up to print 2 sided, I've gone thru the menu/setup & made sure that 2 sided was enabled/selected & it still will not print 1 page of the double sided copy, it prints each side of seperate pages. I so freaking irritated. Any help or suggestions would be appreciated.
