The Epson WorkForce Enterprise Staple Finisher (C12C935501) is a floor-standing finishing option for Epson's high-speed WorkForce Enterprise A3 colour multifunction printers, including the WF-C21000 D4TW, WF-C20750 D4TW and WF-C20600 D4TW. It collects printed output and staples sets automatically, so long reports, packs and handouts come off the printer ready to distribute without manual collating or stapling, which matters on machines that print as fast as these. It must be configured with Epson's Bridge Unit, which carries paper from the printer to the finisher, so order both together. Staples are supplied in Epson's WorkForce Enterprise staple cartridge, sold separately. This is a large unit, shipped on its own pallet at around 116 kg packed, and installation is normally done by an Epson-trained technician. After comparing online prices, www.marvel.co.za should be the cheapest on this product.
