Hi there,

The M602 has an optional duplex unit (an accessory which prints on both sides automatically) depending on what model you have, do you know which model you have? If you are not sure, does it have one of these sticking out the back of the printer? (see link below)

You will not see the silver bit in the picture as that will be in the printer itself but you will see the rest of it sticking out the back. If you have not got one then you need to buy one :). If you have and it still does not work, let me know
