An impurity removal device and an internal gas control method using same are disclosed. An embodiment of the present invention can remove traces of impurities contained in inert gas and supply the gas to a printing unit. Accordingly, the printing unit can be prevented from printing a defective product due to the traces of impurities. Sont divulgués un dispositif d'élimination d'impuretés et un procédé de commande de gaz interne l'utilisant. Un mode de réalisation de la présente invention peut éliminer des traces d'impuretés contenues dans un gaz inerte et fournir le gaz à un groupe d'impression. Par conséquent, le groupe d'impression peut ne pas pouvoir imprimer un produit défectueux en raison des traces d'impuretés. 불순물 제거 장치 및 이를 활용한 내부 기체 제어 방법이 개시된다. 본 발명의 일 실시예는 비활성 기체 내 포함된 미량의 불순물을 제거하여 프린팅부로 기체를 공급할 수 있다. 이를 통해 미량의 불순물로 인하여 불량제품이 인쇄되는 것을 방지할 수 있다.
