I was wondering if anyone knew if a high capacity stacker from the Xerox 700 would be compatible with a Xerox Versant 180 or 280, it's getting to the time to upgrade and wondered if we could use it on a newer machine. I've seen high cap stacker for sale on eBay that it said could be used on new machines and a few other places, but I can't find any documentation from xerox to support this.
