Abstract:
1. A device for cleaning an inkjet head, the inkjet head being provided with ejection outlets through which an ink is ejected and being moveable into and apart from its home position, comprising: a first wiper moving in a direction intersecting with a moving direction of the inkjet head for slidingly contacting a surface of the inkjet head; a second wiper moving in a direction intersecting with the moving direction of the inkjet head for slidingly contacting the surface of the inkjet head; and a container for accommodating an ink residue dissolving liquid which is different from the ink, wherein the ink residue dissolving liquid is transferred to the first wiper before the first and second wipers slidingly contact the surface of the inkjet head during a wiping process by bringing the first and second wipers into contact with the container, and wherein the first wiper is located ahead of the second wiper in a moving direction of the wiping process and is adapted to slidingly contact the surface of the inkjet head at a side portion of the first wiper, so that the ink residue dissolving liquid, while being transferred to the surface of the inkjet head only by the first wiper, is mixed with an ink residue on the surface, and wherein the second wiper is adapted to slidingly contact the surface of the inkjet head at an edge portion of the second wiper after the first wiper so that a mixture obtained by mixing is scraped from the surface of the inkjet head.
