The Plockmatic is a much more robust unit than the Xerox unit. As such, it is also much larger, much more expensive, and often comes with an additional base service fee that is either listed on the service contract, or is hidden/buried into the lease. Either way, the Plockmatic handles more sheets, heavier weights, and has a very nice square fold. If you plan on doing constant production of booklets, upgrade to the trimmings conveyor which automatically conveys the trimmings to an external large waste bin, as opposed to having the unit stop every so often to empty. You can also opt for the larger stacker.
