ABSTRACT:
Drive mechanism for a roll fuser employed in a copier apparatus characterized by the provision of input drive means for rotating a fuser roll and also for rotating a backup roll while the two rolls are disengaged, and further characterized by the provision of a flexible drive shaft or coupling for the backup roll which allows for displacement of the backup roll for engagement with the fuser roll. A sump containing offset preventing liquid and means for applying the liquid to the fuser roll structure are disposed beneath the fuser roll structure which, in turn, is positioned below the backup roll. The drive means is so positioned relative to the sump as to preclude contamination therefrom entering the sump.
