摘要： A print head for ink jet printer having a reduced length in a main scanning direction and an elongated length in an auxiliary scanning direction perpendicular to the main scanning direction. A plurality of linear print head modules are arrayed in the auxiliary scanning direction, and each linear print head module extends in a slanting direction with respect to the main scanning direction by a predetermined angle. Further, each linear print head module has a width in a direction perpendicular to its extending direction. The slanting angle and the width determine scanning pitch extending in the auxiliary scanning direction and can reduces the length of the print head in the main scanning direction.

摘要： A method for manufacturing an inkjet recording head includes an ejecting step, a measuring step, dividing step and applying step. The ejecting step ejects test ink droplets and print ink droplets from nozzles. The measuring step measures ejection results of the test ink droplets. The dividing step divides a plurality of nozzles into a plurality of groups based on the ejection results. The applying step applies a group-based polarizing voltage determined for each group to the piezoelectric elements belonging to a corresponding group to polarize the piezoelectric elements so that ejection results of the print ink droplets fall in a predetermined range.

摘要： A head is formed with a plurality of nozzles and a common ink chamber fluidly connected with the nozzles. A sub ink tank is provided above the head. Ink housed in a main ink tank is supplied into the sub ink tank through the common ink chamber when an image forming operation is not performed. At this time, air bubbles existing in the common ink chamber is brought into the sub ink tank along with the ink supplied from the main ink tank. The air bubbles collected into the sub ink tank in this manner are released into the ambient air through a valve provided to the sub ink tank.

摘要： An ink jet recording head that enables a reduction in the amount of piezoelectric plate consumed, so that costs can be lowered, without lowering efficiency of piezoelectric actuators, even if the piezoelectric actuators are only roughly fixed to the housing, and that also enables accurately and easily positioning the piezoelectric actuators with respect to a diaphragm that defines an ink channel. Assuming that mB is the mass (kg) of the base 3 to which the piezoelectric actuator 5 is fixed and Tfall is the rising edge time (s) of the drive signal that drives the piezoelectric actuator 5, the spring modulus determined from mB and Tfall is 2×mB/Tfall2≧5.0 e6 (N/m). Therefore, the displacement of the piezoelectric actuator can be efficiently transmitted to the ink chamber regardless of the spring modulus of the adhesive agent used to fix the base to the housing.
摘要翻译：一种喷墨记录头，即使压电致动器仅大致固定在壳体上，能够减少压电板的消耗量，从而降低成本而不降低压电致动器的效率，并且还能够精确地和相对于限定墨水通道的隔膜容易地定位压电致动器。假设mB是压电致动器5固定的基座3的质量（kg），Tfall是驱动压电致动器5的驱动信号的上升沿时间（s），则从mB和Tfall确定的弹簧模量是2xmB / Tfall <2 >> = 5.0e <6>（N / m）。因此，无论用于将基座固定到壳体的粘合剂的弹簧模量如何，压电致动器的位移可以有效地传递到墨室。

摘要： An inkjet head is formed with a nozzle, a pressure chamber, a plurality of restrictors, and a common ink chamber. Because the plurality of restrictors are formed in the inkjet head, it is possible to increase a fluid resistance of the restrictors without decreasing the Helmholtz resonant frequency. Accordingly, the inkjet head can be driven at a high frequency while preventing residual pressure wave affecting a subsequent ink ejection.
