Hello hani,
Please take a look at this article for setting up wifi-direct for printing from a phone or tablet.
greed1,
I also noticed in your screenshot of "Required Resources" that Tray 1 is set for A4 short edge feed (SEF). The Banner Page is calling for A4 long edge feed (LEF).
The speed of the machine can be improved if the A4 in Tray 1 is loaded as LEF.
I hope this helps.
greed1,
If you do not need the Banner Page at all then you can turn it off.
I hope this helps.
top page is the unwnated one
If you are using the Xerox Print Services on your phone you should be able to select your paper size. My experience is that most PDFs are setup for A4 so the printer will ask that you load A4 in the bypass tray. If you change the paper size to letter, you shold be able to print from the main tray.
