摘要： In an ink-jet apparatus employing an ink-jet head having a plurality of heaters corresponding to one ink ejection opening, appropriate preliminary ejection is performed per each ejection amount mode set by a heater to be used among a plurality of heaters. Depending upon a set printing mode, printing is performed in one of large, medium and small ejection amount modes. For example, after printing is performed for a predetermined amount by the small ejection amount mode, preliminary ejection during printing is performed in the medium ejection amount mode which is greater in ejection amount than the small ejection amount mode. By this, the interval between preliminary ejections during printing can be set to be longer to prevent lowering of throughput due to the preliminary ejection operations.

摘要： An ink jet apparatus, used with an exchangeable ink jet cartridge having an ink jet head and an ink container, includes a cap, a sucking device and a controller. When the cap caps the ejection orifices of the recording head, the sucking device sucks ink from the ejection orifices. The controller controls the operation of the cap and sucking device. After a sucking operation is performed, the cap is held away from the ejection orifices for a predetermined duration of time; the capping and sucking operations are then repeated.

摘要： An apparatus uses a liquid ejection head including a first liquid passage communicating with an ejection port, a second liquid passage separated from the first liquid passage by a separation wall, and a movable member formed as a part of the separation wall. In the second liquid passage, a thermal energy generation device is arranged at a position opposing to the movable member. The movable member has a free end portion and a fulcrum. Recovery of the first and second liquid passages is performed by suction and/or pressurization. Upon recovery by discharging the liquid in respective liquid passage having higher flow resistance, the pressurizing force and/or the suction force for the liquid passage having higher resistance is set to be greater that the pressurizing force and/or the suction force for the other liquid passage having lower flow resistance.

摘要： An ink jet recording apparatus comprises a detachably mountable ink jet cartridge including an ink jet recording head for ejecting ink into a recording medium and an ink supply source containing ink for supply to the recording apparatus, which ink supply source has electrodes for passing an electric current through the ink in said ink supply source. A resistance-determining circuit determines a reference resistance between the electrodes by applying an electric current thereto when the ink jet cartridge is mounted to the apparatus and determines a test resistance between the electrodes by applying the same electric current thereto after a predetermined amount of recording. The reference resistance is used to calculate a threshold resistance, which is stored for comparison to the test resistance to judge whether or not the amount of ink in the ink supply source has dropped to a level unsuitable for recording.
