摘要： To increase the size of dot printed on a print medium with an on-demand multi-nozzle ink jet head, at least two unit pulses are applied in succession to a piezoelectric element which varies the volume of an ink chamber. The unit pulse has a pulse width substantially equal to a period of Helmholtz natural oscillation determined based on dimensions, materials, and physical properties of an ink channel and the piezoelectric element and other components relating to oscillation. An off duration between adjacent unit pulses applied in succession to the piezoelectric element is preferably set one fifth to one fourth of the unit pulse width.

摘要： To eliminate influence of cross-talk in an on-demand multi-nozzle ink jet head, drive pulses to be applied to piezoelectric elements for driving nozzles aligned in a row are individually adjusted so that the nozzles eject ink droplets at the same speed when the nozzles are driven simultaneously. To the piezoelectric elements which are deactuated during printing, a dummy drive pulse having a voltage level in a range from 50 to 75% of a minimum voltage for ejecting an ink droplet is applied, whereby the ejection speed achieved when individual nozzles are driven approaches the ejection speed achieved when all nozzles are driven simultaneously. As such, the print quality is improved.
摘要翻译：为了消除按需多喷嘴喷墨头中的串扰的影响，单独调整要施加到用于驱动排列成行的喷嘴的压电元件的驱动脉冲，使得喷嘴以相同的速度喷射墨滴喷嘴同时驱动。对于在打印期间被去激活的压电元件，施加具有用于喷射墨滴的最小电压的50至75％范围内的电压电平的虚拟驱动脉冲，由此在驱动各个喷嘴时实现的喷射速度接近所有喷嘴同时驱动时的喷射速度。因此，打印质量得到改善。

摘要： In a print hammer assembly for a dot line printer, print pins are attached to the tip ends of print hammers alternately displaced toward left and right by a predetermined distance from a vertical center of the print hammer, wherein comb portions of a front yoke at both sides of the plunger are made to be an equal width. With such an arrangement, the print pins are not deformed horizontally due to imbalanced magnetic force applied to the associated print hammer at the time of magnetization of a permanent magnet.

摘要： An ink jet printer has a plurality of piezoelectric elements arranged in a matrix form in which each piezoelectric element is connected between one of TS lines and one of selection lines. The TS lines are connected, one by one and in a time sharing manner, to a voltage source E.sub.1 so as to be enabled. The remaining TS lines are connected to a voltage source E.sub.2 so as to be disabled. The selection lines are selectively connected to a voltage source E.sub.3 so as to be enabled. Non-selected selection lines are connected to a voltage source E.sub.4 so as to be disabled. A selected piezoelectric element connected between enabled TS line and enabled selection line is applied with a driving voltage. A non-selected piezoelectric element connected between enabled TS line and disabled selection line, or between disabled TS line and enabled selection line, or between disabled TS line and disabled selection line, is applied with a non-driving voltage. The voltages supplied from the respective voltage sources are selected so that the non-driving voltage is one third or minus one third of the driving voltage. With the thus determined non-driving voltage, no ink droplet is ejected from a nozzle corresponding to the non-selected piezoelectric element while ensuring a sufficient amount of ink to be ejected from a nozzle corresponding to the selected piezoelectric element.
摘要翻译：喷墨打印机具有以矩阵形式布置的多个压电元件，其中每个压电元件连接在TS线之一和选择线中的一个之间。 TS线一个接一个地以时间共享的方式连接到电压源E1，以使其能够被使能。剩余的TS线连接到电压源E2以被禁用。选择线选择性地连接到电压源E3以使能。未选择的选择线连接到电压源E4以被禁用。连接在使能的TS线路和使能选择线路之间的选择的压电元件被施加驱动电压。连接在使能的TS线路和禁用的选择线路之间，或者在禁用的TS线路和使能的选择线路之间或者在禁用的TS线路和禁用的选择线路之间连接的未选择的压电元件被施加非驱动电压。选择从各个电压源提供的电压，使得非驱动电压是驱动电压的三分之一或者三分之一。利用如此确定的非驱动电压，在确保从对应于所选择的压电元件的喷嘴喷射足够量的墨水的同时，不会从与未选择的压电元件相对应的喷嘴喷射墨滴。

摘要： A method of forming a high-quality image on an elongated recording medium, such as a roll of paper sheet. When an image includes a character which stretches between two print regions, a blank line portion of the image is detected. When image forming operation is performed for forming a portion of the image up to the blank line, sheet feed operations are performed. Then, image forming operation for a remaining portion of the image is performed. Because the sheet feed operation will not be performed in the middle of printing of such image, undesirable broken line or gap will not be formed on the printed image.

摘要： An ink jet printer having bubble purging arrangement for discharging bubbles mixed in the ink out of a print head. The print head has a main tank for storing ink, a sub tank for collecting and storing ink, and a manifold fluidly connecting the main tank and the sub tank. The manifold is in fluid communication with the nozzles for supplying ink from the main tank to the nozzles. Three kind of purging modes are provided in accordance with purging position of the print head. Pressurizing pump is selectively connected to the main tank or sub tank or both main tank and the sub tank through a valve arrangement. If the pump is fluidly connected to the main tank only, the ink in the main flows into the sub tank. If the pump is fluidly connected to the sub tank only, the ink in the sub tank flows back into the main tank. By alternating the fluid connection, bubbles mixed in the ink is gradually concentrated at an upper portion of the manifold. If the pump is fluidly connected to both the main tank and the sub tank, the concentrated bubbles is positively discharged outside through the nozzles.
