摘要： An ink-jet recording apparatus having an ink-jet recording head including pressure generating chambers communicatively connected to a nozzle opening and a reservoir, pressure generating member for pressurizing the pressure generating chambers, and a control device for applying drive signals to the pressure generating member. The control device applies drive signals to the pressure generating member. The drive signals contain signals corresponding to print data and signals which minutely vibrate the meniscus of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control device causes ejection of ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates the meniscuses of ink formed at the nozzle openings a preset period of time before or after the discharging of the ink droplets in a printing operation.

摘要： An ink jet recording apparatus includes: a timer (26) that outputs a signal upon measurement of a predetermined time that is longer than a predetermined cycle during a period for which recording heads (8, 9) are released from a cap member (uncapped period) after a print command has been outputted; and a flushing control means (27) that control to move the recording heads (8, 9) to an ink receiving means so that the recording heads jet ink droplets, in response to the signal from the timer (26), and to reset the timer (26). If the predetermined time set to the timer (26) is up during uncapped period, the flushing control means (27) flushes a maximum number of ink droplets, and upon end of a single round of printing, the flushing control means (27) flushes a number of ink droplets corresponding to a time measured by the timer (26).

摘要： A printer has a replaceable cartridge (ink pack), a recording head, and a control section. The recording head ejects ink supplied by the cartridge through a nozzle. The control section detects the retaining amount of the ink in the cartridge and the environmental temperature in the proximity of the printer. Further, the control section sets a threshold value, with reference to which it is determined whether the cartridge needs be replaced by a unused cartridge, to a lower value as the detected environmental temperature becomes higher.

摘要： There are disclosed a multi-color injection molding process for producing an ink-jet printer member comprising a plastics substrate and an elastic material layer that are integrally composited, which comprises melt-injecting into a mold in turn, a material for a plastics substrate and an elastic material composed of a thermoplastic elastomer; and an insert molding process for producing the ink-jet printer member mentioned above, which comprises placing in advance, a plastics substrate of a prescribed form in a mold, and melt-injecting an elastic material composed of a thermoplastic elastomer into said plastics substrate. The above processes are well suited for the production of the ink-jet printer member such as an ink tank valve for supplying a recording head with an ink to be filled in an ink chamber, also of a sealing member which is installed at an ink supply port or on the main body of an ink-jet printer and prevents an ink from leaking through the ink supply port or through the recording head.

摘要： A recording head of an ink-jet-recording apparatus has a plurality of nozzles, a plurality of pressure chambers connected to the plurality of nozzles respectively, and an ink saving chamber connected to the plurality of the pressure chambers for supplying ink into the pressure chambers and for temporarily saving the ink. An ink way is connected to the ink saving chamber for supplying the ink into the ink saving chamber. A driver causes respective pressures in the pressure chambers to change in such a manner that the ink is jetted from the nozzles so as to carry out flushing operations of the nozzles. A flushing controller causes the driver to carry out the flushing operations so that a flushing operation for a pressure chamber arranged relatively further from the ink way is delayed in starting for a predetermined time with respect to a flushing operation for another pressure chamber arranged relatively closer to the ink way. Thus, new ink is easily and sufficiently supplied into the pressure chamber arranged relatively further from the ink way during the flushing operation. This reduces the difference in viscosity of the ink in different portions of the ink saving chamber. Therefore, in the flushing operations, a sufficient volume of ink may be respectively jetted from the nozzles communicating with the pressure chambers, even if the pressure chambers are arranged far from the ink way.
摘要翻译：喷墨记录装置的记录头具有多个喷嘴，分别连接到多个喷嘴的多个压力室和连接到多个压力室的节油室，用于将墨水供应到压力室并用于临时保存墨水。墨水方式连接到储墨室，用于将墨水供应到储墨室中。驱动器使得压力室中的相应压力以这样的方式改变，使得从喷嘴喷射墨水，以便执行喷嘴的冲洗操作。冲洗控制器使得驾驶员进行冲洗操作，使得相对于相对更靠近油墨的另一个压力室的冲洗操作，对于相对于油墨通道布置的压力室的冲洗操作被延迟预定时间墨水方式。因此，在冲洗操作期间，将新墨水容易且充分地供应到与油墨路径相对进一步布置的压力室中。这减少了在节油室的不同部分中的油墨的差异。因此，在冲洗操作中，即使压力室布置成远离油墨路径，也可以从与压力室连通的喷嘴分别喷射足够量的油墨。

摘要： A pressure generator is driven to eject ink droplets from a nozzle orifice such that a plurality of flushing operations are intermittently repeated with a first time interval, when a recording operation of a recording head is not performed. Each flushing operation includes a plurality of ink ejections repeated for a predetermined times with a second time interval which is shorter than the first time interval. The ink near the nozzle orifice is residually vibrated between the flushing operations, so that the viscous ink is diffused and the viscous ink is effectively expelled.
