ABSTRACT:
A user-replaceable fuser cartridge (32) for an electrophotographic printing system. The fuser cartridge (32) includes a first mechanism (40) for partially encasing a fuser (34). When installed, the first mechanism (40) moves in a predetermined direction relative to the fuser (34) but is substantially fixed relative to the surrounding electrophotographic printing system (10). A second mechanism (42) facilitates gripping the first mechanism (40). When the fuser cartridge (32) is removed from the electrophotographic system (10) via the second mechanism (42), a third mechanism (38) selectively encases a portion of the fuser (34) not encased by the first mechanism (40). In a more specific embodiment, the first mechanism (40) includes a shield (40), and the predetermined direction is perpendicular to a longitudinal axis of the fuser (34). The shield (40) is partially curved and concentric with the fuser (34). The second mechanism (42) includes a handle (42) that is mounted on the first mechanism (40). A fuser cartridge receptacle (56) is built into the electrophotographic printing system (10) and has an open end designed to accommodate lateral insertion of the fuser (34). The third mechanism (38) includes a fuser cartridge door (38) that opens and closes upon insertion and removal of the fuser cartridge (32) and accompanying fuser (34) into and out of the fuser cartridge receptacle (56), respectively, thereby exposing the fuser (34) or completely encasing the fuser (34), respectively.
