摘要： A belt fusing apparatus for providing image gloss to a colorant image formed on a receiver member by a reproduction apparatus. The belt fusing apparatus includes a heated fuser roller, a pressure roller in nip relation with the fuser roller, and a steering roller. A fusing belt is entrained about the fuser roller and the steering roller for movement in a predetermined direction about a closed loop path. A cooling air flow is directed at the fusing belt over an area adjacent to the steering roller upstream of the steering roller. The cooling air flow, heated by the action of the air flow cooling the fusing belt, is captured and directed at the fusing belt downstream of the steering roller to preheat the fusing belt.

摘要： Reducing variation in the surface temperature of an externally-heated fusing roller in an electrophotographic machine, the variation typically occurring during the beginning of a fusing run, by detecting the beginning of a fusing run and applying a modified fusing temperature set-point characteristic to the fusing roller. The mode of the electrophotographic machine is monitored to determine whether the machine has changed operating modes, and the application of the modified fusing temperature set-point characteristic to the fusing roller is ceased when the electrophotographic machine changes modes. The force with which the heating rollers engage the fusing roller is controlled within desired operating limits.

摘要： An improved apparatus for cooling or heating, or both, a fuser belt in a process for producing electrophotographic toner images on a substrate. The images are produced by passing a substrate bearing an image through a fusing zone to fuse fusible toner particles comprising the image to produce a substrate bearing a fused toner image, passing the substrate bearing the fused toner image through a cooling zone to produce a cooled substrate, which is thereafter passed to a release zone where it is released to produce the substrate bearing the toner image.

摘要： Reducing variation in the surface temperature of an externally-heated fusing roller (42) in an electrophotographic machine, the variation typically occurring during the beginning of a fusing run, by detecting the beginning of a fusing run and applying a modified fusing temperature set-point characteristic (10) to the fusing roller (42). The mode of the electrophotographic machine is monitored to determine whether the machine has changed operating modes, and the application of the modified fusing temperature set-point characteristic to the fusing roller (42) is ceased when the electrophotographic machine changes modes. The force with which the heating rollers (46, 48) engage the fusing roller (42) is controlled within desired operating limits.

摘要： A fuser, for a reproduction apparatus, having at least one heated fuser roller operating at a setpoint temperature to permanently fix a marking particle image to a receiver member, and a mechanism for controlling temperature droop in the at least one heated fuser roller. The temperature droop controlling mechanism includes an external heat source movable to a position in operative relation with the heated fuser roller and a nonoperative position remote from the heated fuser roller. A logic and control unit regulates heat input to the heated fuser roller, during an idle period, to raise the setpoint temperature for the heated fuser roller a preselected amount relative to the operating temperature set point. At the actuation of the reproduction apparatus job run start, the control unit regulates heat input to the heated fuser roller by the fuser roller heater and the external heat source to raise the fuser operating temperature setpoint a preselected amount relative to the idle temperature setpoint. After a preselected time, the control unit actuates a source of air pressure to direct air flow at the fuser roller for creating an intended thermal gradient in the heated fuser roller. Then at a preselected time later, the control unit enables the first receiver member of a reproduction job run to be transported into operative relation with the heated fuser roller, whereby there is substantially no temperature droop in the heated fuser roller. Further, the logic and control unit actuates the pressurized air source to maintains such air flow for a preselected time after the last receiver member in a reproduction job run has passed through the fuser, whereby overshoot of the fuser roller temperature is minimized.

摘要： A speed control mechanism for a reproduction apparatus including a fuser assembly having pressure, applying members in nip relation to apply pressure to a receiver member bearing a marking particle image to fuse such marking particle image to such receiver member transported through the fuser assembly. The speed control mechanism has an input device for storing parameters required for fusing particular types of receiver members under various desired conditions, and a device for determining fuser control parameters, including overdrive effect, based on information from the input device and selection of a particular receiver member type and certain conditions. A fuser assembly controller then sets fusing parameters based on the determination by the determining device, and adjusts the transport speed of a receiver member through the fuser assembly to compensate for the determined overdrive effect.
