ABSTRACT:
A method and a fusing apparatus for producing a reduced recovery time period from a low energy-saver mode temperature back up to a high fusing temperature. The fusing apparatus includes a heating member for heating and fusing toner images onto a copy sheet; a temperature sensor mounted relative to the heating member for sensing temperature of the heating member; a source of primary power supply for supplying heating power to the heating member; a source of secondary power supply, that is less in level than the source of primary power supply, for supplying secondary heating power to the heated member; and a controller connected to the temperature sensor, and to the source of primary and the source of secondary power supplies for turning the source of primary and the source of secondary power supplies on and off responsively to the temperature sensor. The controller includes a program for, immediately and non-responsively to the temperature sensor, turning on the source of secondary power supply to immediately supply additional heat to the heating member when the fusing apparatus is switched to an energy-saver mode by turning off the primary power supply, thereby delaying a drop of a temperature of the heating member to the low, energy-saver mode temperature level.
