Problems solved by technology

However, in this case, if the liquid nozzle is formed with a diameter of several tens of μm, it cannot withstand a water head of several hundreds of mm. Therefore, it is difficult to mass-produce the moisturizing liquid ejection head, which increases the manufacturing cost of the device.

Abstract

An inkjet printer has a valve unit in a moisture supply path that connects a moisture tank and the fluid nozzles of a moisture discharge head. The moisture discharge head has an operating lever for opening and closing the valve unit, and when the cap approaches the moisture discharge head to seal the fluid nozzle faces of the moisture discharge head, a wiper unit that moves with the cap depresses the operating lever and opens the valve unit. Because the valve unit is open while the fluid nozzle faces are sealed by the cap, moisture leakage and backflow are suppressed.

Description

technical field [0001] The present invention relates to an inkjet printer having a cap covering an ink nozzle surface of an inkjet head and a moisturizing liquid supply mechanism for supplying moisturizing liquid into the cap. Background technique [0002] In an inkjet printer, in order to prevent clogging of the ink nozzle due to the thickening of the ink in the ink nozzle, the ink nozzle is covered with a cap while the inkjet head is in the maintenance position. The ink nozzle face, thereby inhibiting the evaporation of moisture from the ink nozzle. In addition, in order to suppress the occurrence of such clogging, a flushing operation in which ink is ejected from the ink nozzles toward the cap while the cap is facing the ink nozzle surface is periodically performed. In addition, when the ink nozzle is clogged, the ink nozzle surface is covered by the cap, and the negative pressure is generated in the sealed space formed by the nozzle surface and the cap by the suction pu...
