  • Patent number: 6419348
    Abstract: An ink ejecting device in accordance with the invention regulates the ink ejecting velocity for each nozzle. A piezoelectric element thereof is made of piezoelectric materials, internal discrete electrodes and a common electrode. When a cut in the common electrode is formed above an ink chamber, the cut creates an area where an electric field is not generated. The extent of deformation of the piezoelectric element is reduced in that area, whereby the ink ejecting velocity from the ink chamber decreases. In this way, it is possible to regulate the ink ejecting velocity for each nozzle by providing the cut and adjusting the extent of deformation. Further, the size of the cut is in proportion to the deceleration of ink ejecting velocity. This cut in the common electrode is created exactly above the center of the ink chamber so that the deforming portion and non-deforming portion of the piezoelectric element are well balanced.

  • Patent number: 6276790
    Abstract: A tank heater 10 has a DC heater 17b and an AC heater 17a, and a front heater has a DC heater 33x and a DC heater 33y. The DC heater 17b and the DC heater 33x are normal heaters which heat and keep the ink tank and the front panel at predetermined temperatures, respectively. On the other hand, the AC heater 17a and the DC heater 33y are heaters capable of heating up rapidly. When the printer is started up, all of the heaters start generating heat. In this way, the ink tank and front panel can reach required temperatures. Also, by circulating ink in the ink tank, whose temperature is higher than that of front panel, through front panel at a purging operation, the front panel takes less time to be warmed up. Therefore, a time duration required for a preparatory process can be shortened.
