Abstract

Il existait un problème d'avoir des difficultés à enlever une encre fermement collée sur une surface de buse d'une tête à jet d'encre dans les cas de nettoyage de la surface de buse à l'aide d'un balai d'essuie-glace. La présente invention utilise, en tant que balai d'essuie-glace, deux types de balais d'essuie-glace, c'est-à-dire, un balai d'essuie-glace configuré à partir d'un élément poreux, et un balai d'essuie-glace configuré à partir d'un élément élastique. Ensuite, en faisant passer les balais d'essuie-glace à travers un bain de nettoyage contenant un liquide de nettoyage, le liquide de nettoyage est amené à adhérer sur les balais d'essuie-glace. La vitesse de déplacement des balais d'essuie-glace est commandée, et dans les cas d'adhérence du liquide de nettoyage sur la surface de buse, les balais d'essuie-glace sont déplacés à une vitesse élevée, et le liquide de nettoyage est amené à adhérer sans essuyer suffisamment la surface de buse, et dans les cas d'essuyage de la surface de buse, les balais d'essuie-glace sont déplacés à une vitesse faible, et la surface de buse est suffisamment essuyée.
