It sounds like your maintenance kit is defective.
The excess oil leads me to believe that.

OK, same problem, I've gotten through the solution. I can print and have the first page and last page on one side of the large sheet and the two inside pages on the other side, so that is foldable into a booklet.
I start with a 4 page (US letter sized) document I wish to print as a booklet on tabloid paper.
In the (page layout or editing program's) print dialogue, I've said print all pages, set it at 1 page per sheet, then clicked the printer properties button to open the Xerox Workcenter 7345PS option dialogue.
In the Xerox dialog on the "Paper/Output" tab, selected the larger (Tabloid, 11x17" in my case) paper size, selected 2-Sided Print. Then I select the "Layout/Watermark" tab and clicked the Booklet Layout radio button, chose "Landscape" for the Page Layout Option. Note: I saved these settings as "Tabloid Booklet" by clicking the down-arrow to the right of "Driver Defaults" so that I could select them and not have to dial in every one of the settings whilst experimenting.

Make sure the machine and the driver are set for A3 . Most likely the paper tray, or setting in the menu are not correct.
Or the driver paper size is not correct.
