Abstract
A control system for a cooling fan of a laser printer enables selection of fan speed based on the actual degree of usage of the printer. The system provides first and second sets of fan speeds where each set contains information corresponding to a plurality of fan speeds. Information regarding the current operational condition of the fuser of the printer is periodically obtained, preferably during a preset interval. The fan is then operated at one of the fan speeds of the first or second set of fan speeds, with the selection of the first or second set and the selection of one of the fan speeds based on the current operational condition of the fuser. In this manner, the speed of the fan is substantially continuously controlled based on the operational condition of the printer.
