Abstract: An inkjet textile printing apparatus includes a penetrant liquid storage tank, a textile printing colored liquid storage tank, and first to third flow passages. The penetrant liquid storage tank is configured and arranged to store a penetrant liquid that facilitates penetration of a textile printing colored liquid into a fabric. The textile printing colored liquid storage tank is configured and arranged to store the textile printing colored liquid. The first flow passage connects the penetrant liquid storage tank and a first nozzle together. The second flow passage connects the textile printing colored liquid storage tank and a second nozzle together. The third flow passage connects the first flow passage and the second flow passage together and forms a flow passage for supplying the penetrant liquid to the second nozzle.

Abstract: Provided is a liquid injecting apparatus equipped with a liquid injecting head, which is mounted on a carriage and moved reciprocally in a widthwise direction of a target, and a valve unit, which is mounted on the carriage to be supplied with liquid via a supply passage from a liquid retainer and to supply liquid to the liquid injecting head. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve.

Abstract: An ink cartridge in which on one surface of a cartridge case, there are provided a positioning means used in case that the ink cartridge is attached to a recording apparatus, an ink outlet port from an ink pack, an inlet port of the pressurized air and a connection terminal of a circuit board having a data storage means that stores ink information of the cartridge therein, and an ink jet recording apparatus provided with its ink cartridge are provided. According to the ink cartridge of this mode, since the cartridge is exactly positioned and fixed to a holder three-dimentionally by the positioning means, mechanical positional adjustment and electrical connection can be exactly performed, so that operation reliability of the recording apparatus can be improved. Further, in the recording apparatus of this mode, in a state where the cartridge has been mounted on the recording apparatus by the positioning means, the connection terminal of the board is located at the upper portion of the ink outlet port.

Abstract: A valve unit 36 is placed in an ink flow passage 35 between an ink cartridge 8 and a recording head 7 and can be controlled in association with the cleaning operation of the recording head 7. Under the control of a drive controller, the valve unit 36 holds for a predetermined time a state in which negative pressure produced by a suction pump is accumulated, and is opened after the expiration of the predetermined time or is opened with the negative pressure accumulated and driving the suction pump is continued. The air bubbles remaining in a stuck state in the ink flow passage can be peeled from the ink flow passage together with an instantaneous fast ink flow produced as the valve unit 36 is opened, and the peeled air bubbles can be discharged effectively from the ink flow passage following the subsequent ink flow.

Abstract: Liquid is sent from a liquid retainer to a liquid ejection head via a liquid supply line by pressurization force generated by a pressurization device that is driven by a driver. A method for cleaning a liquid ejection apparatus includes drawing the liquid from the liquid ejection head through a nozzle by a suction device; and obtaining a liquid remaining amount of the liquid retainer. The method further includes determining an operational speed of the driver in correspondence with a result of the calculation; and operating the driver at the determined operational speed when drawing the liquid by the suction device. Thus, liquid is consumed completely without being wasted.

Abstract: An ink cartridge includes an ink pack 21 which discharges ink from an ink outlet 22 upon reception of pressure by air pressure; an outer case 20a, 20b which houses the ink pack 21 therein with the ink outlet 22 exposed so that the ink pack 21 can be pressurized by the air pressure, and includes a pressurized air inlet 23 that is connectable to an air source for pressurizing the ink pack 21; and a pressure adjusting unit 30 which is housed in the outer case and discharges air in the outer case to the outside so that pressure in space of the outer case is kept at a setting value. The setting value of the pressure adjusting unit 30 is set to an optimum value for each ink cartridge, whereby the ink pack can be pressurized in an optimum state regardless of the air pressure from the pressurized air inlet 23.
