The Epson 2/4 Hole Punch Unit for Staple Finisher-P1 (C12C936811) adds automatic hole punching to Epson WorkForce Enterprise A3 colour multifunction printers. Documents leaving the printer are punched with two or four holes, ready to file in binders and lever-arch files, which saves time in offices, schools and print rooms that produce reports and handouts in volume. The unit fits inside the Epson Staple Finisher-P1 and cannot be used on its own: according to the distributor, it must be configured together with the Staple Finisher-P1 and the Bridge Unit A-P1 and B-P1. Epson lists it for the WorkForce Enterprise AM-C4000, AM-C5000 and AM-C6000. It is finished in white to match the printer. Installation is normally done when the finisher is fitted.
