How do I make duplex copies?
1 Load your original document in the MFP.
2 From the home screen, touch the Copy icon.
3 Touch the button that looks like how you want your copies to print.
The first number represents sides of the original documents; the second number represents
sides of the copy.
For example, select 1 --> 2-sided if you have 1-sided originals and you want 2-sided copies.
4 Press Start.
1-->1-sided 1-->2-sided
2-->1-sided 2-->2-sided
