摘要： A control method for an ink jet printer capable of a non-discharge nozzle driving operation for stimulating and vibrating an ink meniscus in each ink nozzle of the ink jet head to prevent nozzle clogging does not lead to a drop in print speed. An ink jet head 30 is moved on a carriage 302. Prior to printing on a printing medium (block B2), this non-discharge driving operation (block B31) is performed while the carriage 302 is moving the ink jet head to the print position. Printing is therefore not delayed by the non-discharge driving operation, and nozzle clogging can be prevented without lowering the print speed.

摘要： An electrostatic actuator comprising opposing electrode members displaced relatively by an electrostatic force is provided with improved durability so that electrostatic attraction between opposing members does not drop and the opposing electrode members do not stick together. Hydrophobic films of hexamethyldisilazane (HMDS) are formed on a surface of segment electrode and a bottom surface of a diaphragm (common electrode) of an eletrostatic actuator wherein the diaphragm forms a wall of an ink chamber in an ink jet head. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high. An electrostatic actuator with high durability and operating stability can thus be achieved.
摘要翻译：提供包括相对于静电力移动的相对电极构件的静电致动器，其具有改善的耐久性，使得相对构件之间的静电吸引力不会下降，并且相对的电极构件不会粘在一起。在分段电极的表面和静电致动器的隔膜（公共电极）的底表面上形成六甲基二硅氮烷（HMDS）的疏水膜，其中隔膜在喷墨头中形成墨室的壁。 HMDS分子小于PFDA分子，因此即使在相对电极之间的间隙窄的情况下也可形成均匀的，无变化的疏水膜。 HMDS疏水膜的耐久性和膜稳定性也很高。因此，可以实现具有高耐久性和操作稳定性的静电致动器。

摘要： An improved ink jet head is provided. This improved ink jet head comprises a diaphragm, which is part of an ink chamber. The diaphragm includes a segment which contacts an opposing wall by a drive voltage lower than that for the rest of the diaphragm. The ink jet head also comprises an opposing wall opposite to the diaphragm. When the pressure for ink droplet ejection is generated, the segment of the diaphragm contacts the opposing wall, creating an extremely low compliance state. After ink droplet ejection, the segment of the diaphragm separates from the opposing wall, producing a high compliance state that absorbs the pressure created in the ink chamber by oscillation in the ink channel. Thus, pressure in the ink chamber resulting from ink vibration in the ink path including the ink chamber is buffered to prevent satellite emissions. When plural different gaps are formed between the diaphragm and the opposing wall to create the segments requires different drive voltage for contacting the opposing wall, the part of the diaphragm contributing to ink droplet ejection can be selected by appropriately controlling the voltage applied to opposing electrodes. The mass of the ejected ink droplets can thus be variably controlled. Drive at a lower drive voltage is also possible because contact with the opposing wall is propagated from the segment of the diaphragm to the other parts of the diaphragm. A high ink nozzle density is also achieved in an ink jet head using an electrostatic actuator without increasing the drive voltage.
摘要翻译：提供改进的喷墨头。这种改进的喷墨头包括作为墨水室的一部分的隔膜。隔膜包括通过低于隔膜其余部分的驱动电压接触相对壁的段。喷墨头还包括与隔膜相对的相对壁。当产生用于墨滴喷射的压力时，隔膜的部分接触相对的壁，产生非常低的顺应性状态。在墨滴喷射之后，膜片的分段与相对的壁分离，产生高的柔顺性状态，其通过墨水通道中的振荡吸收在墨水室中产生的压力。因此，缓冲由包括墨水室的油墨路径中的油墨振动引起的油墨室中的压力，以防止卫星排放。当在隔膜和相对壁之间形成多个不同的间隙以产生段时，需要不同的驱动电压来接触相对的壁，可以通过适当地控制施加到相对电极的电压来选择有助于墨滴喷射的隔膜的部分。因此可以可变地控制喷射的墨滴的质量。在较低的驱动电压下驱动也是可能的，因为与相对壁的接触从隔膜的段传播到隔膜的其它部分。在使用静电致动器的喷墨头中也可以实现高墨水喷嘴密度，而不增加驱动电压。
