This is a Lexmark-compatible finisher accessory (branded "Lex" in this listing) for Lexmark's CS94x and CX94x series printers, offering staple finishing with a 2/3 hole punch option — a slightly different hole configuration from the 2/4-hole variant of the same finisher family also carried in this catalog, matching regional filing/binder standards that vary between 2/3-hole and 2/4-hole punch patterns. Rather than a standalone printer, this is an optional add-on unit that attaches to a compatible Lexmark device to automate document finishing: it staples completed print or copy jobs and punches holes into the output, removing the need for an office to do that finishing work by hand after printing. As a specific finisher accessory, it requires a matching, compatible Lexmark CS94x/CX94x printer already in place, and exact output bin/staple capacity should be confirmed against Lexmark's accessory catalogue for this model before purchase.
