Abstract
A hub-based drive coupling mechanism for a fusing assembly, including a gear operatively coupled to a motor; a hub member; and a backup roll having a shaft rotatably coupled to the gear via the hub member, the gear including an outer cylindrical portion having a plurality of tabs disposed along an inner surface thereof, the hub member including an annular portion having a plurality of protrusions radially extending therefrom, and the backup roll shaft having a pin member. The gear rotates for a first fraction of a revolution without rotating the hub member and the backup roll due to the tabs of the gear not contacting the protrusions of the hub member, and rotates for a second fraction of the revolution with the hub member due to contact between the tabs and protrusions, but without rotating the backup roll.
