We have been using the M775z+ for a while now and recently discovered a problem with duplex printing. We are using pre printed paper in tray 4 which is used for letters by the administration department. Whenever they print a one-sided document it will come out perfectly fine. But when they want to print double-sided documents the second page is printed on the front of the paper and the first page is printed on the back. Can anyone tell if there is an option for this and where to find it?
We are using driver version 61.135.4.13581 on Windows 2008 R2
Thx in advance,
Arjen
