Abstract

1.청구 범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

별도의 급지카셋트를 구비하는 전자사진 현상방식 화상형성장치에 급지카셋트내의 용지 장착 유무와 용지잼을 검출하는 기술에 관한 것이다.The present invention relates to a technique for detecting paper jams and paper jams in a paper cassette in an electrophotographic development type image forming apparatus having a separate paper cassette.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

급지카셋트내의 용지 장착과 급지에 따른 용지 잼을 하나의 센서만을 사용하여 동시에 검출한다.The paper jam in the paper feed cassette and the paper jam caused by feeding are simultaneously detected using only one sensor.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

동작개시명령의 입력에 응답하여 용지를 급지하기 시작하고, 미리 설정된 시간내에 용지가 대기위치에 도달하는가를 급지 검출센서를 통해 검사하여, 용지가 설정 시간내에 대기위치에 도달하지 못할 경우에는 “용지없음/용지 잼” 메시지를 디스플레이 한다.When paper starts to be fed in response to an operation start command, the paper feed sensor detects whether the paper reaches the standby position within the preset time, and when the paper does not reach the standby position within the preset time, None / Paper Jam ”message is displayed.
