PURPOSE:To prevent organic solvent from leaking outside a recorder without exchanging any filter by a method wherein impurities are prevented from entering from a printing head opening part by fitting a simple device to an ink circuit. CONSTITUTION:An ink container 1, an ink feed pump 2, an ink filter 3, a pressure regulating valve 4, and a nozzle 5 are in series connected. A gutter 6 exists at a position capable of receiving ink jetted from the nozzle 5. The gutter 6 and an ink recovery pump 7 are also connected in series. Besides, the ink container 1 is connected to a solvent processor 10. The solvent processor 10 discharges cleaned air from which the solvent is removed and sends it to a printing head 9. |
