Abstract: What is disclosed is a multi-function system which receives media printed with ink having thermo-reactive properties with the ink being visually transparent on that media, and which processes that media such that the ink becomes visually perceptible. One embodiment of the present system comprises an input tray for receiving printed media into a transport path along which the media travels. A cooling element resides in proximity to that transport path for changing a temperature T of the media to T?TL. A temp-normalizing element is positioned along the transport path downstream of the cooling element for changing a temperature of the media such that the media's temperature T can be normalized back to a temperature range TL<T<TH prior to the media being deposited into an output tray. A user interface enables a user to perform various functions. Various embodiments of a user interface are disclosed.
