Abstract: A printing apparatus including a heat roller, a pressure roller, a fusing apparatus, and a method of controlling a fusing temperature of the printing apparatus. The printing apparatus includes a heat roller, a first temperature sensor which senses a temperature of the heat roller, a first heat source which is installed inside the heat roller, a second heat source which is installed inside the heat roller and has a lower heat capacity than the first heat source, a pressure roller, and a control unit which controls the first and second heat source based on the temperature sensed by the first temperature sensor. The printing apparatus further includes a third heat source which is installed inside the pressure roller, wherein the control unit controls the first, second and third heat sources to reduce a warm-up time, power consumption, flicker and overshoot, while providing a stable fusing operation.

Abstract: A fusing apparatus in an image forming apparatus that heats a fusing unit by applying an induced current is provided. The flicker characteristics of the fusing apparatus are improved by gradually increasing the amount of induced current applied to the fusing unit for a predetermined amount of time so that the amount of induced current applied to the fusing unit is prevented from severely varying. The fusing apparatus comprises a fusing unit which is resistance-heated or induction-heated by applying an induced current and fuses toner onto paper using the heat. The fusing apparatus further comprises a pulse width modulation (PWM) signal generation unit which generates a PWM signal in response to the ON signal so that the amount of induced current input to the fusing unit gradually increases to a reference current.

Abstract: PURPOSE: A fusing device of an electrophotographic image forming device is provided to shorten a warming-up time necessary for initial driving. CONSTITUTION: If electricity is supplied to a lead line(117), a resistance coil(114a) generates heat by the electricity. A part of the heat is transmitted to a cylindrical roller(113) and the rest of the heat is transmitted to a heat pipe(115). An operating fluid(116) contained in the heat pipe is evaporated by the transmitted heat. The heat of the gaseous operating fluid is transmitted to the cylindrical roller through a heat generator(114). The heat of the cylindrical roller is transmitted to a silicon rubber layer(112), so a surface temperature of a fusing roller increases to a target temperature appropriate for fusing a toner. The toner is fused on paper by fusing nips formed by the silicon rubber layer while the paper passes through a gap between the fusing roller and a compressing roller.

Abstract: A power control apparatus and a technique for a fusing roller in an electrophotographic image forming apparatus includes measuring a temperature of a fusing roller, comparing the measured temperature of the fusing roller with a predetermined first control temperature, changing a duty ratio of the power supplied to the fusing roller when the temperature of the fusing roller reaches the predetermined first control temperature, and supplying power to the fusing roller at the changed duty ratio until the temperature of the fusing roller reaches a predetermined target fusing temperature. In the power control technique, as the temperature of the fusing roller increases toward a target fusing temperature, the duty ratio of the power supplied to the fusing roller is lowered. Therefore, a temperature overshoot and temperature ripple during printing operation can be reduced at a lowered temperature-increasing rate. In addition, a problem of short life span of the fusing roller caused by damage of a heater of the fusing roller can be prevented.
Abstract translation: 一种用于电子照相成像设备中的定影辊的功率控制装置和技术包括：测量定影辊的温度;将测量的定影辊的温度与预定的第一控制温度进行比较;将供给的功率的占空比改变为 当定影辊的温度达到预定的第一控制温度时，定影辊以改变的占空比向定影辊供电，直到定影辊的温度达到预定的目标定影温度。 在电力控制技术中，随着定影辊的温度朝着目标定影温度增加，供应到定影辊的功率的占空比降低。 因此，在降低升温速度时，可以降低印刷操作过程中的温度过冲和温度波动。 另外，可以防止由定影辊的加热器的损坏引起的定影辊寿命短的问题。
