+The GUI includes some features that attempt to detect the attributes of an Epson printer whose model is not included in the configuration. First press "Detect Printers". If the printer is not in the configuration, press "Detect Access Keys". If the output does not show errors, press "Detect Configuration". These commands produce a tree view and a text view, which are useful to analyze whether there is a configured model that might be close or possibly same to target one. Notice that these operations take many minutes to complete and the printer shall be kept switched on for the whole period. Temporarily disabling the auto power-off timer is suggested.
