Disclosed is a detached touch pad allowing for remote programming of a touch screen User Interface (UI) contained on an electrophotographic printing machine. The Light Emitting Diode (LED) array used on the Cathode Ray Tube (CRT) of the UI is duplicated on the touch pad with electrical signals connected in parallel with the UI. For reference, the UI possesses the same log map, only transparent, to help prompt an operator of the touch pad and help guide selection of the required programming available on the UI. The printing machine recognizes a beam interrupting combination on either the UI or the touch pad as a programming input.
