Question about Di1611

[DadO]

I have only one in my area so don't know much obout it. I tried to show a costumer how to use an 2on1 option like u can in new bizhubs 162,163.
When i try to activate 2on1 i get "function unavailable" message.

How do I activate this option on Di1611?

You need to have A4R paper loaded in a tray.
