Abstract

본 발명은 정착기를 화상를 복사하는 장치에서 정착기의 가열로울러의 표면온도를 설정온도로 유지시켜 토너가 균일하게 복사지에 융착되어 화상을 선명하게 복사할 수 있도록 정착기의 온도를 제어하는 방법을 제공한다. 일반적으로 정착기를 구동할 시 가열로울러의 가열동작을 수행하는 과정에서 온도감지센서의 응답속도가 늦어지는 관계로 상기 가열롤러의 표면온도가 설정온보다 높아지는 오버슈트가 발생된다. 이를 제거하기 위하여, 먼저 상기 가열롤러를 가열하는 동작을 수행하는 과정에서 오버슈트가 발생되지 않는 임계온도를 설정하고, 이런 임계 온도를 경계로 가열롤러의 가열롤러의 가열동작을 제어하는 동시에 그 제어회수를 카운트한다. 그리고 제어회수가 일정회수를 초과하는 경우 실제의 설정온도에 이를 때까지 제어함으로서 정착기의 오버슈트현상을 제거한다.The present invention provides a method of controlling the temperature of the fixing unit so that the surface temperature of the heating roller of the fixing unit is maintained at the set temperature in the apparatus for copying the image, so that the toner is uniformly fused to the copy paper so that the image can be vividly copied. In general, an overshoot occurs in which the surface temperature of the heating roller becomes higher than the set temperature in response to a slow response speed of the temperature sensor during the heating operation of the heating roller when the fixing unit is driven. In order to eliminate this, first, a threshold temperature at which no overshoot occurs in the process of heating the heating roller is set, and the heating operation of the heating roller of the heating roller is controlled at the same time as the threshold temperature. Count the number of times. And if the control frequency exceeds a certain number of times by controlling until the actual set temperature to eliminate the overshoot phenomenon of the fixing unit.
