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 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： An inkjet recording head includes a base member, an ink channel unit, a plurality of piezoelectric elements, and a dynamic vibration absorber. The ink channel unit is formed with a plurality of nozzle holes and a plurality of ink pressure chambers. The ink channel unit includes a diaphragm that defines part of each ink pressure chamber. Each piezoelectric element has one end fixed to the base member and another end attached to the diaphragm. Each piezoelectric element generates displacement in a displacement direction for deforming the diaphragm to eject ink droplets through a corresponding one of the plurality of nozzle holes. The dynamic vibration absorber is mounted on the base member for damping vibrations of the base member due to a resonance, the resonance occurring in a frequency range less than or equal to a predetermined frequency.

摘要： A computer portion 201 of a printer includes a memory storing a printer driver software 201a and nozzle profile data 211. The printer driver software 201a includes a raster image processor (RIP) 203. When the RIP 203 receives document data 209, the RIP 203 converts the document data 209 into bitmap data 210 which is one dot/one bit data for 300 data/inch. Then, the nozzle data converting portion 204 converts the bitmap data 210 into driving data 212 based on the nozzle profile data 211. At this time, each bit of the bitmap data 210 is replaced by 16 bits. That is, the data amount is increased to 16 times of the bitmap data 210. Accordingly, fine control of ink ejection can be achieved.
