The Epson WorkForce Enterprise Finisher Bridge Unit (C12C935101) is the paper transport unit that connects the Epson WorkForce Enterprise WF-C20600, WF-C20750 and WF-C21000 D4TW printers to an external finisher. It carries printed sheets from the printer's output to the Staple Finisher or Booklet Finisher, so jobs can be stapled, sorted or made into booklets automatically. Epson specifies that the bridge unit must be configured together with either the Booklet Finisher or the Staple Finisher; it does not finish documents on its own. It is a genuine Epson option made in Indonesia. It is needed by offices, print rooms and reprographics departments adding professional finishing to a WorkForce Enterprise printer, and it is supported by the printer's own driver and finishing settings. Please confirm your printer model and finisher choice before ordering. After comparing online prices, www.marvel.co.za should be the cheapest on this product.
