Abstract: An ink cartridge for a printing apparatus providing ink to a print head through a tapered ink supply needle and removably attached to the print head. The ink cartridge comprises an ink chamber for containing ink, an ink supply port, a packing member and a valve device. The ink supply port supplies ink from the ink chamber to the print head of the printing apparatus, the ink supply port comprising an external opening. The packing member is provided in the ink supply port and forms an ink channel for allowing a flow of ink. The packing member seals the ink supply needle of the printing apparatus by fitting therewith. The valve device is contained in the ink supply port and elastically abuts against the packing member. The valve device selectively opens and closes the ink channel in conjunction with the ink supply needle.

Abstract: An ink flow passage 7f is formed from an ink storage chamber of an ink cartridge 7 to an ink supply port. A passage control system 7j is located in the ink flow passage. The passage control system is capable of opening and closing the ink flow passage when receiving a drive force from an actuator 32. Particularly, air bubbles A1 staying on a filter member 22 within an ink supplying needle 21 is effectively discharged to a capping system 9 in a manner that a negative pressure is accumulated in an inner space of the capping system 9 in a state that the passage control system 7j is placed to a valve closing state. The passage control system 7j is provided in the ink cartridge. Accordingly, every time the ink cartridge is exchanged with a new one, the passage control system 7j is also exchanged with a new one. Accordingly, the printing function restoring operation performed through a cleaning operation based on the negative pressure accumulation is improved in reliability.

Abstract: The recording medium guide member is placed along the main scanning direction scanned by the carriage mounted with a recording head, and ink-receiver holes for receiving ink discharged from the recording head are formed on the guide member in positions beyond the edges of the recording medium being conveyed. Ink absorbing materials are placed in said ink-receiver holes, and a discharged ink accumulating means that cumulatively counts the amount of ink discharged into the ink absorbing materials is provided. The amount of ink discharged into the ink-receiver holes can be controlled by the discharged ink accumulation means so that contamination of the left and right edges or the top and bottom as well as left and right edges of the recording medium, caused by excessive ink collecting in the ink-receiver holes, can be avoided.

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: When ink is sucked from the nozzles during a cleaning process, a rubber cap having a plural number of small spaces independently operable for ink suction is applied to a print head, and only the small space associated with a clogged nozzle of those nozzles of the print head is connected to a suction pump. A user looks up in advance the number and location of a clogged nozzle, judges the cause of the clogging of the nozzle on the basis of the number and location of the clogged nozzle, and selects a suitable type of cleaning process, a selective cleaning (based on the specified-nozzle suction) or a conventional cleaning (based on the all-nozzle suction). A valve unit is arranged in an ink supply path located between an ink cartridge and a recording head. The valve unit controls the opening and closing of the ink supply paths between the ink cartridge and the nozzle openings during the cleaning operation of the recording head. For example, air bubbles entered into the recording head when the ink cartridge is replaced, can be discharged by opening the valve unit. By closing valve units disposed on the other recording head that does not receive a new ink cartridge, unnecessary ink suction discharging ink equally through all nozzle openings can be avoided. Therefore, an ink jet recording apparatus capable of reducing the running costs is provided.

Abstract: A cap member (10) which is brought into contact with a nozzle forming surface of a recording head (15) to seal up the nozzle forming surface, and a wiping member (11) which may be brought into sliding contact with the nozzle forming surface of the recording head (15) are disposed on a cap holder (31). With progress of a cleaning operation in which ink is placed under a negative pressure, and sucked and discharged from the recording head, a cap retaining member (50) is moved upward and placed to a set state, whereby blocking the slanting and downward movement of the cap member (10). Then, the wiping member (11) located on the cap holder (31) slides on the nozzle forming surface to wipe the nozzle forming surface. To a flushing operation, the cap retaining member (50) is moved downward and placed to a reset state. In this state, the wiping member (11) does not slide on the nozzle forming surface.
