A liquid droplet jetting apparatus includes a jetting head unit which has a nozzle which jets droplets of a liquid, and a heat generating section, a suction port which is formed in the jetting head unit, and which opens near the nozzle, and a suction device which sucks air around the nozzle from the suction port, and cools down the heat generating section of the jetting head unit by the air which is sucked. Since the heat generating portion is cooled down by the air sucked from the suction port by the suction device, it is possible to reduce a possibility of the heat of the heat generating section being transferred to the jetting head unit, and destabilizing an operation of the jetting head unit. Moreover, since the suction port opens near the nozzle, it is possible to suck fine liquid droplets together with air around the nozzle.

An ink jet image forming apparatus, which is improved in a structure of an ink supply device so as to minimize an influence due to a pressure loss generated in an ink flow passage, is provided. The ink jet image forming apparatus includes a print head to eject an ink to a printing medium, an ink tank to store the ink, an ink circulation passage through which the ink circulates between the ink tank and the print head, a pressure controller which has an ink storage unit communicating with the ink circulation passage and an air storage unit communicating with external air, a valve mounted in the ink circulation passage between the ink tank and the pressure controller, a pump mounted in the ink circulation passage and pumps the ink, and a control unit to control operations of the valve and the pump.

An ink jet printer including a movable printhead assembly having printheads including ink and nozzles for printing onto a recording medium, a maintenance assembly having liquid application members for cleaning and priming the printheads, and a customer replaceable, multiple function capping assembly for assuring effective cleaning and continued quality operation of the printheads. For a first function, the capping assembly has a housing defining a fluid chamber containing cleaning liquid, a liquid flow aperture formed through the housing from the fluid chamber, and a snap-in, snap-out valve connector mounted over the liquid flow aperture for supplying cleaning liquid to the maintenance assembly, and for enabling economical, easy customer removal and replacement of the capping assembly within the ink jet printer. For another function, the capping assembly has a fluid release aperture formed through the housing from the fluid chamber, and gasket members mounted around the fluid release aperture for capping, sealing and humidifying the printheads when in a capped position on the capping assembly. The ink jet printer then has a liquid conduit member connected to snap-in, snap-out valve connector of the capping assembly and to the maintenance assembly supply cleaning liquid from the fluid chamber to the maintenance assembly, thus assuring effective cleaning and continued quality operation of the printheads.

An ultrasonic liquid wiper for an ink jet printer maintenance station has a cleaning nozzle confrontingly aligned but spaced from printhead nozzles suspected of having viscous plugs of partially dried ink. A cleaning solution is held within the cleaning nozzle by surface tension to form a meniscus and is caused to bulge toward into contact with the printhead nozzle face and form a bridge of cleaning solution therewith. In addition to dissolving ink, the cleaning solution is ultrasonically excited by a piezoelectric material immediately upstream of the cleaning nozzle to provide a high frequency energized liquid wiper to facilitate viscous plug removal without having physical contact with the printhead nozzle face, thereby preventing wear of any hydrophobic coating on the nozzle face. A vacuum nozzle is positioned on each side of the cleaning nozzle to remove the cleaning solution deposited on the nozzle face, together with any ink dissolved therein. The cleaning nozzle optionally dwells for predetermined time periods to more effectively loosen and/or dissolve the viscous plugs of ink. The cleaning nozzles may have different concave shapes to aid in the ultrasonic cleaning action of the cleaning solution.
