well, there is a know issue on the 75xx
when i had an office document created in landscape, i wasnt able to print in duplex with SEF, it always printed LEF , regardless the setting in the driver... Xerox released a new firmware (internal) to fix that issue, so its best to contact xerox to obtain the latest firmware at this moment = 061.121.221.29800
from notes : Using PS driver, the Duplex Short Edge Flip setting is ignored and the duplex output is flipped on the long edge.
I'm printing a Jetform sales order that has terms and conditions as Landscape on the front and the sales order form as Portrait on the back (duplex). This works fine on a Workcentre 7335 but both sides print out Portrait on the 7535. I tested this with Microsoft Word (Portrait and Landscape as duplex) and it worked ok to the 7535. Anyone doing this with Jetforms on a 7535?
