| description | PROBLEM TO BE SOLVED: To provide a cleaning means suitable for an inkjet head using a strong acid ink having a high surface tension, in particular, such as a PEDOT-PSS. SOLUTION: An inkjet head has a connection port 11 connected to an ink supply means 30. A plurality of ink ejection nozzles 12 are coupled to the connection port 11. Ink supplied from the ink supply means 30 is ejected from each of the ink ejection nozzles 12 of the inkjet head through the connection port 11. The cleaning means is equipped with connection switching means (31, 41, 51) that selectively couples the connection port 11 to one of the ink supply means 30, a cleaning liquid supply means 40, and a dry air supply means 50 upon performing cleaning. When cleaning is performed, the connection port 11 is first coupled to the cleaning liquid supply means 40 so as to eject the cleaning liquid from each of the ink ejection nozzles 12. Next, the connection port 11 is coupled to the dry air supply means 50 so as to eject the dry air from each of the ink ejection nozzles 12. COPYRIGHT: (C)2010,JPO&INPIT |
