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： 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 method for setting a heater element of a fuser assembly to a consistent starting condition to achieve consistency in heating power measurement is provided. The heater element is heated to a first predefined temperature when the temperature of the heater element is less than the first predefined temperature. The temperature of the heater element is maintained within a predefined range for a predefined period of time. This sets the temperature of the heater element in the fuser assembly to a consistent starting condition. Thereafter, the heating power estimation measurement is made and heating power supplied to the fuser assembly is estimated. This controls the heating power delivered to the fuser assembly in a consistent manner.

摘要： Fuser heater element damage due to excessive heating power is prevented by estimating available power supply heating power for proper power control. The estimate is performed by applying a predefined portion of the heating power available from the power supply to the heater element. The predefined portion is determined so that the heater element will not be damaged even if the power supply is at the maximum voltage level of any power supply that may be encountered. The temperature of the heater element is measured, and, if below a predefined temperature, a heating power estimate is made. If not, the heater element is heated by applying power in accordance with a stored heating power estimate from the last heating power estimate. A heating power estimate is made each time the heating element is heated from a temperature below the predefined temperature.

摘要： A method of controlling throughput of media passing through a heat fixing device includes the steps of initially conveying media to the heat fixing device at a nominal interpage gap, and counting a number of substrates conveyed through the heat fixing device. After a predetermined number of substrates have been conveyed through the heat fixing device, a temperature related measurement is obtained at the heat fixing device; and the interpage gap is increased when the temperature related measurement is a predetermined value. The interpage gap may be increased a large amount for a temperature related measurement corresponding to a narrow media, and the interpage gap may be increased a small amount for a temperature related measurement corresponding to nearly narrow media. The temperature related measure is obtained from a temperature sensor located in spaced relation to a temperature sensor providing a signal for controlling power to a heater for the heat fixing device.
