Abstract

본 발명은 레이저 프린터의 리셋 회로에 관한 것으로, 보다 상세하게는 사용자가 레이저 프린터를 사용하며서 시스테 에러 또는 용지 걸림이 발생되거나 인쇄 작업을 수행하다가 인쇄를 취소 할 경우 레이저 프린터의 전원을 온, 오프(ON/OFF)함이 없이 레이저 프린터의 외부에 설치된 리셋 키를 누르고 상기 리셋키의 눌림에 따라 동작하는 리셋 회로를 내장시킴으로써 레이저 프린터를 리셋시켜 시스템 홀트(SYSTEM HALT)된 또는 인쇄 취소된 레이저 프린터가 정상 동작되도록 하는 레이저 프린터의 리셋 회로에 관한 것이다.The present invention relates to a reset circuit of a laser printer. More specifically, when a user uses a laser printer and a system error or paper jam occurs or a print job is canceled and the printing is canceled, the laser printer is turned on or off. Laser printers that have been system-halted or canceled by resetting the laser printer by pressing the reset key installed on the outside of the laser printer without the (ON / OFF) and incorporating a reset circuit that operates according to the pressing of the reset key. The reset circuit of the laser printer is configured to operate normally.
