摘要:
Embodiments herein include an apparatus that can comprise any heating device, such as one having an outer surface adapted to contact items, such as sheets of print media, and a rotatable air outlet (vent, jet, blower, etc.) positioned next to the heating device. The air outlet can be, in one embodiment, part of a tube-shaped air pleneum. In some embodiments, the air outlet can comprise a slit, perforations, rows of jets, etc. and the air outlet can have a length at least as long as the width as the fuser. The rotatable air outlet can be positioned to blow air to remove the items from the heating device and can rotate from a first position to a different second position.

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.
摘要:
An actuation system and method, the system including a tubular having a passage, and an assembly disposed with the tubular. The assembly includes a degradable restriction, the restriction only partially blocking the passage prior to being degraded. The assembly is configured to receive and prevent further movement of a restrictor through the tubular prior to the restriction being degraded. The assembly is further configured to release the restrictor when the restriction is degraded.

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.

A method and apparatus for automatically adjusting nip width based on a scanned nip print in an image production device is disclosed. The method may include automatically inserting a sheet of media into a fuser nip in the image production device upon receiving a signal from a user interface, the fuser nip being an intersection of the fuser roll and the pressure roll, generating a nip print in the fuser nip, the nip print being an image created from the pressure between the fuser roll and the pressure roll, scanning the nip print, determining if a nip width adjustment is required based on the scanned nip print, the nip width being the distance of an arc length created by an intersection of the fuser roll and the pressure roll, and if it is determined that a nip width adjustment is required based on the scanned nip print, adjusting the nip width.

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.
