As a result, the output quality is greatly reduced.

상기의 문제점을 해결하기 위해 안출된 본 발명의 목적은, 잉크의 분사전 또는 분사후에 출력매체에 부착되어 있는 먼지를 강제로 제거할 수 있는 기능을 가지는 먼지제거가 가능한 헤드어셈블리를 제공하는 데에 있다.SUMMARY OF THE INVENTION An object of the present invention devised to solve the above problems is to provide a dust removing head assembly having a function of forcibly removing dust adhering to an output medium before or after spraying ink. have.
