The Epson 2/4 Hole Punch Unit for the Inner Finisher (C12C936971) adds automatic two- or four-hole punching to Epson WorkForce Enterprise A3 colour multifunction printers fitted with the compact inner finisher. Punched output is ready to go straight into binders and lever-arch files, which saves time in offices, schools and reprographics rooms that print reports and handouts in volume. It is an option for the inner finisher and is not a standalone device; the distributor states it must be configured with the Epson inner finisher. Epson lists it for the WorkForce Enterprise AM-C4000, AM-C5000 and AM-C6000. It is finished in white to match the printer. Check your finisher configuration before ordering, as the staple finisher uses a different punch unit (C12C936811).
