Braille Label Kit
The optional Braille Label Kit contains transparent Braille labels that can be placed on the device control panel (except the numeric keys), as well as, areas such as the document feeder and paper drawers for improved device access. Due to the conventional layout of the numeric keypad (which has a protruded indicator on the "five key") visually-impaired users can easily enter numeric information. The Braille Label Kit can be used with imageRUNNER and imageRUNNER ADVANCE devices, as well as some, imagePRESS, and LASER CLASS Facsimile devices.
