A belt fuser system has a cleaning member with a changeable wick. The cleaning member has a first belt cleaning surface and a second belt cleaning surface. The cleaning member rotates about a longitudinal axis for bringing the first belt cleaning surface and the second belt cleaning surface in contact with a back of a fuser belt.

A belt-roll fuser system includes a belt-roll fuser module that is movable to engage and disengage to a main frame of the belt-roll fuser system. The belt-roll fuser has an internal pressure member that defines a fusing nip with an external pressure member of the main frame when the belt-roll fuser module is engaged. The belt-roll fuser module is movable by a latch, and when engaged, a nip load path crosses through a point at which the latch attaches to the belt-roll fuser module.

A belt-roll fuser stripping system has a stripping shoe and a stripping shim. The shim is support by a support member. The support member supports the shim to maintain a desired nip pressure profile, and reduce deformation and wear of the shim and belt-roll fuser components.

Apparatuses useful for printing and methods for stripping media from surfaces in apparatuses useful for printing are disclosed. An apparatus useful for printing including a first member including a first outer surface; a second member including a second outer surface; a belt including an inner surface and an outer surface; a first nip formed by contact between the inner surface of the belt and the second outer surface and contact between the outer surface of the belt and the first outer surface; and a stripping mechanism including a stripping member disposed internal to the belt. The stripping member is positionable relative to the first nip to vary a pressure applied by the outer surface of the belt against the first outer surface downstream from the first nip. The media are stripped from the outer surface of the belt after exiting from the first nip.

A temperature-changing pressure roller assembly is provided and includes (a) a rotatable pressure roller including a cylindrical sleeve having an outer surface, and an inner surface defining a hollow interior to the rotatable pressure roller having a first end and a second and opposite end; (b) a vortex tube assembly for simultaneously producing a hot air stream and a cold air stream, the vortex tube assembly being connected to the hollow interior of the rotatable pressure roll; and (c) control device connected to the vortex tube assembly for selectively controlling flow of the hot air stream and the cold air stream thereof through the hollow interior of the rotatable pressure roller, thereby selectively changing a temperature of the cylindrical sleeve of the pressure roller.

An apparatus (100) and method (300) that adjusts a fuser nip width in an apparatus that can include a fuser member having a fuser nip configured to fuse an image on media is disclosed. The method can include feeding (320) a media sheet in a media sheet travel direction through the fuser nip. The method can also include sensing (330) a media sheet exit temperature of the media sheet after the media sheet exits the fuser nip. The method can also include adjusting (340) a fuser member nip width according to the sensed media sheet exit temperature, where the fuser nip width is substantially parallel to the media sheet travel direction.

A rapid warm-up and cool-down pressure roll assembly is provided and includes (a) a rotatable pressure roll including a cylindrical sleeve having an outer surface, and an inner surface defining a hollow interior to the rotatable pressure roll; (b) a thermoelectric assembly sheet positioned within the hollow interior and having a first substrate facing the inner surface of the cylindrical sleeve, a second substrate, an electric current flow path therethrough, and electric current input and output terminals associated with the electric current flow path; and (c) an electric current input switching device connected to the electric current input and output terminals for enabling selective reversing of a direction of electric current flow through the electric current flow path, thereby reversing which of the first substrate and the second substrate of the thermoelectric assembly sheet is hot and which is cold, and therefore selectively enabling a rapid warm-up or rapid cool-down of the cylindrical sleeve of the pressure roll.
