Abstract
Contact fusing system for affixing powder images to copy sheets which images are electrostatically or otherwise formed on the copy sheets. The fusing system is characterized by a pair of fuser roll members one of which is heated and mounted relative to the other roll member to form a nip therewith, the rolls being mounted so that they are permanently in nip. Rotational movement of the roll members is effected by the main drive of the copier apparatus in which the fuser system is employed and they are operatively coupled to the main drive via a one-way clutch which enables the copy sheet to be manually moved through the fuser system in the event of a paper jam which automatically stops the fuser system along with the rest of the machine. Since the two rolls are always maintained in nip such manual movement will effect complete fusing of the toner images to the copy sheet.
