The Océ concept eliminates the need for an auxiliary duplexing tray. In an Océ copier or printer, double-sided copies are produced in one pass through the machine, whereby the second image is copied onto the rear of the page directly after the first image is copied onto the front.

The use of an auxiliary tray restricts the amount of double-sided copies available and is particularly susceptible to static build up on the copy pages with subsequent paper jams and time and paper wastage. This is a limiting feature in many copiers but not with Océ copiers.

Making double-sided copies is as easy and reliable as making single-sided copies. So there is less waste, less time lost, and costs are reduced.
