  • Publication number: 20060244792
    Abstract: A liquid ejection apparatus includes a liquid ejection head and a controller (CPU, ASIC). The liquid ejection head is mounted on a carriage that reciprocates and ejects liquid toward a target. The controller controls a flushing mode of an in-range flushing and a flushing mode of an out-of-range flushing when the liquid ejection head ejects liquid as the carriage reciprocates. The flushing mode of the in-range flushing is performed in a reciprocation range of the carriage outside the target during ejection performed by the liquid ejection head. The flushing mode of the out-of-range flushing is performed outside the reciprocation range of the carriage reciprocates during ejection performed by the liquid ejection head.

  • Publication number: 20060209119
    Abstract: The liquid jetting apparatus includes a head member having a nozzle, a supporting member that that can support a medium, a scanning mechanism that can cause the head member to relatively move with respect to the medium, and a liquid jetting unit that can jet liquid from the nozzle. An area storing unit stores a relative area to which liquid can be jetted from the nozzle while the head member is caused to relatively move by the scanning mechanism. An out-of-jetting micro-vibrating-area setting unit can set out-of-jetting micro-vibrating areas before and after the relative area. A micro-vibrating unit causes liquid in the nozzle to minutely vibrate. An out-of-jetting micro-vibrating controlling unit causes the micro-vibrating unit to operate when the head member is located in the out-of-jetting micro-vibrating areas, while the head member is caused to relatively move by the scanning mechanism, based on the out-of-jetting micro-vibrating areas and head-position information.

  • Publication number: 20050195227
    Abstract: A liquid ejection head ejects liquid droplets toward a target medium while being moved in a first direction. A temperature detector detects temperature in a peripheral region of the liquid ejection head. A signal generator generates a first signal including first pulses operable to drive the liquid ejection head so as to eject the liquid droplets toward a unit region in the target medium at a first frequency, and a second signal including second pulses operable to drive the liquid ejection head so as to eject the liquid droplets toward the unit region at a second frequency which is lower than the first frequency.

  • Publication number: 20050050025
    Abstract: An information gathering system is provided which can gather information from input data or output data of a terminal, without requiring a specific operation of a user. The system includes servers and terminals connected over a network. In this system, at least one or more keywords are specified in advance and stored in a keyword list holding unit. Then, a keyword recognition unit detects a match or association between one of the keywords and information input to an input unit or output from an output unit in the terminal. With this arrangement, specific information is acquired.

  • Patent number: 6811241
    Abstract: A first evaluation signal includes a first excitation element adapted to excite pressure fluctuation in liquid contained in the pressure chamber and a first ejection element which follows the excitation element after a first time period to eject a first liquid droplet from the nozzle. A second evaluation signal includes a second excitation element adapted to excite pressure fluctuation in liquid contained in the pressure chamber and a second ejection element which follows the excitation element after a second time period to eject a second liquid droplet from the nozzle which is longer than the first time period. The first evaluation signal is supplied to the pressure generating element to measure a first ejected amount of the first liquid droplet. The second evaluation signal is supplied to the pressure generating element to measure a second ejected amount of the second liquid droplet. An ejected amount ratio of the first ejected amount and the second ejected amount is calculated.
