B205 2-sided print from tray - 1st side orientation
Product Name: Xerox B205 Multifunction Printer
Operating System: macOS 10.14 - Mojave
In case you need to know quickly and w/out experimentation, here's an image I taped to my Xerox B205 printer. This is assuming you are using the regular, front exit tray. I'm getting excellent feed & image results with premium 24lb 8.5 X 11 from Staples.
