PROBLEM TO BE SOLVED: To control power modes in printers, copiers, and multi-function devices.SOLUTION: A printer, copier, or multi-function printing device (MFP) operates in a reduced power mode. In this mode, a controller 128 identifies a path of motion of an object external to the printer with reference to signals from a proximity sensor housed in the printer. The controller 128 connects one or a plurality of components to electric power to transition to an elevated power operating mode if the identified path corresponds to a path history that is stored in a memory 150 of paths of object paths that have occurred prior to operation of the printer, copier or MFP. The activation of the components reduces a delay that an operator perceives as the printer, copier or MFP transitions from the reduced power operating mode to the elevated power operating mode, thus significantly reducing power consumption during operation. |
