Everytime my Xerox Phaser 8560 prints the cleaning page (the one with all the red, green, and black squares) the paper james in the exit cover. No matter if it comes from tray 1 or tray 2. No other jamming problems, only with this sheet.
Well, turns out it was the maintenance kit. Although it supposedly had 28% life left in it, I guess it wasn't any good. I replaced it with a new one, and everything's working perfectly. This was a genuine Xerox kit, so I'm surprised at the poor quality. It was the extended capacity, don't know if that had anything to do with it. The one I've replaced it with is the normal capacity.
