ABSTRACT:
A heat and pressure fuser for fixing toner images to substrates. A dual heating lamp arrangement is utilized for elevating the surface temperature of a heated fuser roll. The operation of the dual heat lamps is controlled using dual thermistors for maintain steady state temperature fluctuations to .+-.3.degree. F. The thermistors are positioned, one adjacent the inboard end of the fuse and the other adjacent the outboard end thereof. The outboard thermistor is used to determine the desired on time of the fuser lamp and the inboard thermistor is used to determine which of the two lamps is on. If the inboard temperature is below a predetermined target value a 14 inch lamp is turned on. If the inboard temperature is at or above a predetermined target value an 11 inch lamp is turned.
