The money cleaning liquid injection nozzle 21 ejects the cleaning liquid 12 in order to wash out the ink and impurities adhering to the nozzle 1 () and its periphery (hereinafter referred to as "cleaning area"), and the air injection nozzle 22 is attached. The cleaning liquid 12 remaining in the cleaning area is blown and dried, and the cleaning liquid feeding means is for forcibly feeding the cleaning liquid from the cleaning liquid tank to the cleaning liquid spraying nozzle 21. The air feeding means is for forcibly feeding the air in the air injecting nozzle 22, and the waste liquid recovering means is a waste liquid retained in the washing tank 24, and is discharged from the waste liquid tank by a negative pressure state. The tube 29 is recovered in the liquid tank 14. The cleaning liquid 12 of a preferred embodiment is composed of a colorless solvent (for example, a main component solvent for dissolving the ink) having a factor for dissolving the ink. However, the inks generally used in ink jet printers can be classified into dye systems or pigment systems. The term "dye" refers to a coloring agent which is dispersed or fused by a carrier medium as a molecule. The carrier medium is in a liquid state or in a solid state at room temperature. Usually, the carrier medium used is water or a mixture of water and an organic co-solvent. 97106019 10 200918334 α is a water-based component, and contains a coloring agent therein, and contains glycerin, etc. for the purpose of preventing clogging or the like. Wetting agent. When the carrier medium is water, the ink generally has the disadvantage of being low in water. △ "Pigment" means a coloring agent which is stable in the carrier medium but which is dispersed or suspended in a small particle shape, and is usually stabilized by the use of a dispersing agent in order not to cause aggregation and precipitation. Many of such compounds are known. For example, a pigment such as an organic pigment or carbon black is micronized by using a surfactant or a dispersing agent, and a pigment ink or the like which is a coloring agent is used by being dispersed in a medium such as water. The cleaning mechanism of the present invention is applicable regardless of the dye system or the pigment system. The viscosity of the ink is mainly in the low viscosity of several tens of cps, but under the premise that it can be sprayed out, it can also be applied to the medium viscosity of several hundred cps. In addition, the present invention is applicable to, for example, a printed substrate. Wiring pattern 2: Lubricant coating for small parts, or outdoor light-resistance display material: ,: V-curing ink printing, etc. The net cleaning machine 24 has a nozzle 1G covering the ink jet head 1 and its periphery, which is located below the t ink surface 1.
