摘要： Undesirable deflection of partitioning walls between ink pressure chambers is prevented during ink discharge operations even when the partitioning walls are made very thin to achieve a high density inkjet head. The diaphragms of the discharge nozzles of the inkjet head as well as the diaphragms of the non-discharge nozzles are all driven to contact the corresponding individual electrodes, and this diaphragm to individual electrode contact state is maintained in the non-discharge nozzles while the diaphragms of the discharge nozzles are released from individual electrodes to discharge ink. After printing is completed the diaphragms of the non-discharge nozzles are slowly released from the corresponding individual electrodes at a speed that will not cause undesirable ink discharge. By thus maintaining low compliance in the ink pressure chambers of the non-discharge nozzles, deformation of the partitioning walls between discharge and non-discharge nozzles due to change in the ink pressure can be reliably prevented. A drop in ink discharge performance due to such partitioning wall deformation can be reliably prevented, and printing with high resolution, precise print quality can be easily achieved.
摘要翻译：即使当分隔壁非常薄以达到高密度喷墨头时，在喷墨操作期间也防止了油墨压力室之间的分隔壁的不期望的偏转。喷墨头的排出喷嘴的隔膜以及非排出喷嘴的隔膜都被驱动以接触相应的单个电极，并且该隔膜保持在非排放喷嘴中，而隔膜保持在单独的电极接触状态的排出喷嘴从各个电极释放以排出墨。在完成打印之后，不排出喷嘴的隔膜以不会导致不期望的墨水排放的速度从相应的单独电极缓慢释放。通过这样维持在非排出喷嘴的墨压力室中的低柔顺性，可以可靠地防止由于墨压力的变化引起的排出喷嘴与非排放喷嘴之间的分隔壁的变形。可以可靠地防止由于这种分隔壁变形引起的喷墨性能下降，并且可以容易地实现具有高分辨率，精确打印质量的打印。

摘要： An ink-jet head ejects an ink droplet from an ink nozzle by the charging and discharging between a counter electrode and vibrating plates. The counter electrode comprises a main electrode and an auxiliary electrode, which is provided on the ink-nozzle's side in common with the vibrating plates. Auxiliary charging between the auxiliary electrode and the vibrating plates is effected to vibrate a meniscus in the ink nozzle without ejecting a useless droplet. Consequently, the ink is prevented from forming a film on the meniscus, and an increase of the viscosity of the ink due to evaporation of the ink solvent is prevented by diffusing the ink in the ink passage.

摘要： In an ink jet head that reduces failure or abnormality in ink ejection, electric charge/discharge is applied between opposed electrodes and diaphragms to eject ink droplets from ink nozzles. Each of the opposed electrodes includes a main electrode and a sub-electrode formed on the nozzle side and in common with sub-electrodes for the other diaphragms. Auxiliary electric charge is applied between the sub-electrode and the diaphragms so that the menisci or ink in the ink nozzles vibrate without ejecting unnecessary ink droplets and to shorten the time for tail portions of ejected ink columns to leave the ink nozzles. Ink in ink channels is diffused so that the ink viscosity does not increase due to evaporation of ink solvent. Also, the menisci in the nozzles are drawn into the ink chambers so that unnecessary ink droplets are not ejected immediately after printing ink droplets are ejected.
摘要翻译：在降低墨水喷射的故障或异常的喷墨头中，在相对的电极和隔膜之间施加电荷/放电以从墨水喷嘴喷射墨滴。每个相对电极包括形成在喷嘴侧上的主电极和副电极，并且与用于其它隔膜的子电极共同。辅助电荷施加在子电极和隔膜之间，使得墨水喷嘴中的半月板或墨水不会喷出不必要的墨滴并缩短喷射墨水柱尾部离开墨水喷嘴的时间。油墨通道中的油墨扩散，使得由于油墨溶剂的蒸发而导致油墨粘度不增加。此外，喷嘴中的半月板被吸入墨室中，使得在喷墨墨滴之后不再喷出不必要的墨滴。
