Bizhub 283, how to batch copy with a scan

I know there is an option for it but I have been looking into it for a few days now and cannot find even how it is called, let alone to do it.
So, I am copying a big batch of papers that need to have a small stripe (width od A4, about 3cm in height) with information on top. I do it the hardcore oldschool way, putting the stripe on the glass and then copy paper by paper in an neverending automatic cycle.
Does anyone have any idea what I am talking about and hopefully help me?
