摘要： An improved control method is provided that combines conventional ON-OFF control and conventional phase-angle control to reduce the AC inrush current to an electrical load, such as a tungsten halogen lamp used as a heating element in a laser printer, so that the power control circuit can satisfy both the European flicker and European harmonic requirements. Phase-angle control is applied to the load for a very short time period when it is initially energized, then the control circuit quickly switches from phase-angle control to standard ON-OFF control to reduce the harmonics generated by conventional phase-angle control methodologies. The electrical load exhibits three possible states: power full OFF, power ramp-up, and power full ON. During the power ramp-up state, power supplied to the load is adjusted by delaying the phase angle of the firing pulse relative to the start of each AC half cycle. Depending upon whether or not the system demand has been satisfied, the load's state can be changed from either power ramp-up to power full ON, or from power ramp-up to power full OFF. The phase-angle control methodology used during the power ramp-up state must be of sufficient time duration to reduce the amount of flicker to pass the European flicker test. However, this power ramp-up time interval must also be as short as possible to keep the harmonics as small as possible to the load, without the requirement of adding a large AC current harmonic attenuation inductor, which would otherwise be needed to pass the European harmonic test.
摘要翻译：提供了一种改进的控制方法，其结合常规的ON-OFF控制和常规的相位角控制，以减少对诸如在激光打印机中用作加热元件的卤素灯等电负载的AC浪涌电流，使得功率控制电路可以满足欧洲闪烁和欧洲谐波要求。当初始通电时，相位角控制在很短时间内被施加到负载上，然后控制电路从相位角控制快速切换到标准的ON-OFF控制，以减少常规相位角控制方法产生的谐波。电气负载表现为三种可能的状态：电源全关，功率提升和电源全开。在功率提升状态期间，通过相对于每个AC半周期的开始延迟点火脉冲的相位角来调节提供给负载的功率。根据系统需求是否得到满足，负载的状态可以从功率提升到电力全部接通，或者从功率提升到全部关断。在功率提升状态期间使用的相位角控制方法必须具有足够的持续时间，以减少闪烁量以通过欧洲闪烁测试。然而，这种功率提升时间间隔也必须尽可能短，以保持谐波尽可能小到负载，而不需要增加大的交流电流谐波衰减电感器，否则将需要通过欧洲谐波测试。

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 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.
