Start by looking at the documents you are going to copy. If those documents already have print on both sides and you want the output to print on both sides, you want to use 2-2 Copying. If the documents in your hand have print only on one side and you want the output on both sides of the paper, you want to use 1-2 Copying.
If the documents in your hand are double sided and you want to have each of those sides on its own sheet of paper, you want to use 2-1 Copying.
If required, enter a password to activate the copier. Position your originals face up on the document feeder or face down on the document glass. Now touch Simplex/Duplex as shown in the graphic.
Make sure to touch the correct mode(i.e. 1→2) that you want. Press Start on the keypad to begin copying.
