ABSTRACT:
Heat and pressure fusing apparatus having a thin-walled tubular fuser roll cooperating with a rigid pressure roll to pass copy substrates therebetween with the toner images on the substrates contacting the fuser roll. The rolls are supported in pressure engagement such that the axes are skewed relative to each other to compensate for roll deflection aggravated by hoop deflection of the thin-walled fuser roll. Thermal degradation of the elastomeric conformable coating is reduced by standing by at a low temperature and quickly warming up to run temperature.
