Claims (1)

광량검지센서를 구비한 전자사진 복사기의 복사농도 조절방법에 있어서, 첫 스캔인지 검사하여 첫 스캔일시 초기 광량값을 설정하고 첫 스캔플래그를 "1"로 셋팅하는 제1과정과, 상기 제1과정 수행중 광량검지 데이타를 입력하여 상기 데이타값이 설정 범위내에 존재하지 않을시 에러를 디스플레이 하고 기계를 정지시키는 제2과정과, 상기 제2과정에서 데이타 값이 설정 범위내에 존재할시 상기 데이타값에 대응하는 광량이나 바이어스 전압의 디지탈 값을 결정하여 출력하는 제3과정으로 구성됨을 특징으로 하는 자동 농도 조절방법.A method for adjusting the radiation density of an electrophotographic photocopier having a light intensity detection sensor, the method comprising: a first step of setting an initial amount of light at the first scan date and setting the first scan flag to "1" by checking whether it is the first scan, and the first step A second step of displaying an error and stopping the machine when the data value is not within the setting range by inputting light quantity detection data during execution; and corresponding to the data value when the data value is within the setting range in the second step. And a third process of determining and outputting a digital value of an amount of light or a bias voltage. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
