    摘要： A method for processing a media sheet by advancing the media sheet through a nip in a media processing device is disclosed. The nip is capable of being configured by abuttingly coupling a heater device to a pressure roller. A first heater device temperature of the heater device and a pressure roller temperature of the pressure roller are determined. A signal for configuring the nip is generated upon determining the first heater device temperature and the pressure roller temperature. A second heater device temperature of the heater device is determined on generating the signal. A closure of the nip is verified for advancing the media sheet through the nip based on the first heater device temperature, the second heater device temperature and the pressure roller temperature. The media sheet is advanced through the nip on verifying the nip as closed.

    摘要： An apparatus is provided for fixing toner to a substrate including a heated fusing roller having a fusing surface. A heater element is located inside the fusing roller. A nip forming member cooperates with the fusing roller to define a fusing nip. A passive temperature control structure including a pair of members is located adjacent opposing end sections of the fusing roller, the passive temperature control structure operating to retain heat in the end sections. The passive temperature control structure may include heat reflecting members located adjacent to peripheral end portions of the hot roller to reflect heat back to the peripheral surface. In addition, the passive temperature control structure may include an end reflector facing axially toward an interior area or the hot roller for reflecting heat back to the interior of the hot roller. The temperature control structure may also comprise a heat dissipating structure including a heat absorbing roller engaged with the fusing roller or ventilation windows formed in a cover over the fusing roller.

    摘要： A method and apparatus for providing a relatively short period of time for a fuser assembly to be ready to perform a fusing operation. Included is a fusing assembly having a heat transfer member and a backup member positioned to engage the heat transfer member so as to define a fusing nip therewith; and a controller coupled to the fuser assembly, wherein during a period of time when the fuser assembly is not performing a fusing operation, the controller activates the heat transfer member while causing the backup member to rotate at one or more relatively slow speeds relative to a fusing speed of the fuser assembly.

    摘要： A fuser for an electrophotographic imaging device according to one embodiment includes a stationary pressure member having an elongated body with an outer surface. The pressure member is substantially transparent and/or substantially translucent and permits the passage of radiant heat therethrough. An endless fusing belt having a flexible tubular configuration is rotatably positioned about the pressure member. The pressure member is positioned around a heating lamp for transmitting radiant heat through the pressure member to an inner surface of the fusing belt. A backup roll opposes the fusing belt. The pressure member is configured to apply pressure contact to the fusing belt against the backup roll to form a fuser nip between the backup roll and a segment of the fusing belt.

    摘要： A belt fuser assembly for a color EP printer that quickly warms up the fusing belt before allowing a first sheet of print media to run through the printing stations at the fuser assembly. The warm-up cycle includes: (1) a preheat mode, (2) a first portion of a belt temperature warm-up mode, (3) a second portion of the belt temperature warm-up mode, and (4) a tight belt temperature control mode. The preheat mode operates the fuser's heater at less than full power, and prevents the fuser belt from rotating. The first portion of the belt temperature warm-up mode operates the heater at full power, and the fuser belt begins rotating, but not at its full speed. The second portion of the belt temperature warm-up mode operates the heater at less than full power, and the fuser belt begins rotating at its full speed.

    摘要： A fuser hot roll for use in an electrophotographic process is disclosed. This roll is constructed such that the center portion of the roll's length has a greater thermal mass per unit length than each of the end portions of the roll's length. This can be accomplished either by constructing the center portion from a material which has a higher thermal capacity than the materials used for constructing the end portions, or constructing the center portion such that it is thicker than the end portions of the roll. The rolls of the present invention provide a simple way for regulating the fuser temperature such that it is uniform across the length of the hot roll, is uniform between the transitory (heat up) state and the steady state, and minimizes hot roll temperature overshoot during the transitory phase. The image fixing apparatus which incorporates this hot roll is also disclosed.
