摘要： A method of controlling a fuser having a heating member and a pressure member wherein the pressure member temperature is estimated from parameters set by a print engine and measured media throughput. Media throughput is used to determine a predicted pressure member steady temperature (SST) associated with the operating mode of the fuser. The predicted pressure member SST and an estimated pressure member starting temperature are used to calculate a pressure member temperature change, and the calculated temperature change is used to determine an estimated pressure member temperature. The print engine compares the estimated pressure member temperature to a predetermined temperature and reduces the heating member set point temperature if the predetermined temperature is exceeded to avoid the pressure member reaching a maximum temperature.

摘要： Two temperature areas are set at a higher temperature side and at a lower temperature side of target temperature respectively. The power stage of the temperature areas at the higher temperature side is set to −1 and the power stage of the temperature areas at the lower temperature side is set to +1. Thus, a current value is varied little and generation of flicker can be reduced. Further, A temperature can be always converged into the target temperature. When a temperature is in a temperature area near to the target temperature, the power stage is maintained except for a case in which a temperature has passed through a temperature area other than this near temperature area and the target temperature area and enters this near temperature area for the first time. Thus, an amplitude of power can be suppressed.

The heater has a line shape orthogonal to a direction in which a recording sheet carrying an unfixed toner image formed with toner in accordance with image information is transferred. The endless belt is rotated with an inner surface thereof sliding over a surface of the heater. The pressure roller is arranged at a position opposite to the heater relative to the endless belt and is held for rotation in contact with the endless belt under pressure to form a nip therebetween. The heater controller energizes the heater in accordance with the image information.
