This is a 2/3-hole punch finishing module for Xerox ColorQube 83xx-series and WorkCentre/ AltaLink 9x/96x, CS96x and Mx95x-series multifunction printers, fitted to the printer's finisher to automatically punch printed output for ring-binder filing as it comes off the machine. The "2/3" punch pattern is the standard hole configuration used in North American ring binders, as opposed to the 4-hole European standard. Offices and print rooms running high volumes of binder-ready documents - manuals, reports, training materials - add a punch finisher like this to skip a manual hole-punching step entirely. Note: the source listing is a terse parts-compatibility string with no further technical detail supplied.
