Abstract
A fuser assembly includes a heated member and backup member forming a fusing nip. Nip loading springs on either ends of the fusing nip bias into contact the backup member and the heated member. Bellcranks contact the nip loading springs. Rotatable latches on either ends of the fusing nip act on the bellcranks to compress or relax the nip loading springs to open or close the fusing nip at respective distal or proximate ends of the fuser assembly. The rotatable latches are acted upon by corresponding latches of an access door of an imaging device that when opened provides access to the fuser assembly in an interior of the imaging device. The rotatable latches are independently movable. They can reside in different positions, yet allow closing the door of the imaging device.
