Abstract

복사기의 토너(Toner)농도 제어 방법에 관한 것으로, 특히 실제 드럼상에 맺히는 상에 대한 토너 농도를 감지하여 최적의 복사화질을 얻을 수 있는 복사기의 토너농도 제어 방법에 관한 것이다.The present invention relates to a toner concentration control method of a copier, and more particularly, to a toner concentration control method of a copier to obtain an optimal copy quality by sensing a toner concentration on an image formed on an actual drum.

대전기(12)을 온시켜 일정시간 지연한 후 싸이드 이레이즈 램프(16)를 온시켜 가화상을 생성하여 상기 가화상의 농도를 검출하고, 상기 검출된 토너 농도를 기준 토너 농도 데이타와 비교하여 토너 농도 데이타가 상기 기준 농도도 데이타보다 작을 경우 토너 공급 모터를 구동시키기 위한 제어신호를 출력하여 농도를 제어한다.After the charger 12 is turned on for a predetermined time and the side erase lamp 16 is turned on to generate a virtual image, the density of the virtual image is detected, and the toner density is compared with the reference toner density data. If the density data is smaller than the reference density data, the density is controlled by outputting a control signal for driving the toner supply motor.
