摘要： A method for controlling power to an electrical load using dual pulse width modulation (PWM) to minimize in-rush current to the electrical load, such as a heater element. An output from a power source, supplying an alternating current, is modulated by a first PWM control signal to provide a first modulated power level to the electrical load. The first modulated power level is modulated by a second PWM control signal to control power supplied to the electrical load at the first modulated power level. The first PWM control signal operates to control the number of half cycles of current in order to provide one-third, two-thirds or full cycle power. The second PWM control signal operates to define a duty cycle and period for providing the power defined by the first PWM control signal to the electrical load.

摘要： In accordance with a first aspect of the present invention, a system is provided for fusing an unfixed toner image to a substrate comprising a rotatable hot fusing roll and a backup belt assembly. The belt assembly may comprise a backup belt and a housing structure including a nip forming pressure roll. The backup belt may be wrapped about the housing structure including the nip forming pressure roll. Preferably, the pressure roll applies a force to the belt so as to form the sole nip region between the rotatable fusing roll and the backup belt.

The belt assembly may include a backup belt and a housing structure having a nip forming pressure roll. The backup belt may be wrapped about the housing structure including the nip forming pressure roll. The pressure roll includes a crown shape and the housing structure preferably includes structure for creating a generally uniform tension across the length of the belt in a direction transverse to a process direction.

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.
摘要翻译：一种控制具有加热构件和压力构件的定影器的方法，其中根据由打印引擎设定的参数和所测量的介质通量来估计压力构件温度。介质通量用于确定与定影器的操作模式相关联的预测压力成员稳定温度（SST）。使用预测的压力构件SST和推定的压力构件起始温度来计算压力构件温度变化，并且使用所计算的温度变化来确定估计的压力构件温度。如果超过预定温度，则打印引擎将估计的压力构件温度与预定温度进行比较，并且降低加热构件设定点温度，以避免压力构件达到最大温度。
