The Epson C12C935171 is a 2/4 hole punch unit for Epson WorkForce Enterprise multifunction printers. It fits to the printer's Staple Finisher or Booklet Finisher and punches either two or four holes in printed sheets as they are output, so documents come off the printer ready to file in ring binders or lever-arch files with no separate punching step. That saves time in offices that produce large volumes of reports, policies, training packs or records which end up in binders, and it gives neater, consistently aligned holes than punching stacks by hand. The unit is made in Japan and ships in a package weighing about 5.8 kg. Note that a compatible Staple Finisher or Booklet Finisher must already be installed on the printer for the hole punch to work.
