Abstract
An apparatus for fusing toner images to suitable substrates or copy sheets of paper includes a self-learning heater that substantially prevents 'droop' or drops from a desired setpoint in the fusing temperature of the apparatus. The heater itself has a variable temperature control setpoint, and is connected to means for monitoring temperature variations due to heat lost by the apparatus to the substrates or copy sheets, as well as, to means for varying the temperature control setpoint of the heater in direct response to such monitored temperature variations. The heater as such, is capable of substantially preventing significant variations in the fusing temperature of the apparatus by effectively replacing such heat loss by the fusing apparatus.
