Claim Text:
1. A method of operating a printer comprising: decoupling with a controller a graphical display device in the printer and at least one other component in the printer from electrical power while a first proximity sensor in the printer is operatively connected by the controller to electrical power; receiving at the controller a plurality of signals from the first proximity sensor that generates signals corresponding to a position of an object with respect to the printer; identifying with the controller a path of movement of the object in proximity to the printer with reference to the plurality of signals generated by the first proximity sensor; identifying with the controller a degree of similarity between the identified path of movement for the object and each cluster of object paths in a plurality of object paths stored in a memory, the plurality of object paths stored in the memory includes a plurality of clusters of object paths that precede data being received through the graphical display device and a plurality of clusters of object paths that do not precede data being received through the graphical display device; detecting that the identified degree of similarity between the identified path of movement for the object and one cluster of object paths that precedes data being received through the graphical display device exceeds a predetermined threshold; and operatively connecting with the controller the graphical display device in the printer and the at least one other component in the printer to electrical power in response to the controller detecting that the degree of similarity between the identified path of movement of the object and the one cluster of object paths that precedes data being received through the graphical display exceeds the predetermined threshold.
