ABSTRACT:
A cold pressure fuser comprising three rolls two of which have their axes parallel to each other and form a nip through which copy sheets having toner images pass. The third roll serves to apply the required load to the other two rolls to create the required pressure in the nip therebetween. The axis of the third roll is overskewed relative to the other rolls such that the distribution of the load between it and the roll which it contacts is peaked at its center and zero at its ends. A pair of load releasing arms are provided to remove the loading from the rolls to thereby facilitate paper jam clearance.
