摘要： A liquid ejection head includes nozzles, separate chambers, a common chamber, inlet portions, a filter unit, and ribs. Droplets of liquid are ejected from the nozzles. The separate chambers are communicated with the nozzles. The inlet portions are communicated with the corresponding separate chambers. Liquid is supplied from the common chamber to the separate chambers through the inlet portions. The filter unit is disposed between the inlet portions and the common chamber to filter liquid in an area across the separate chambers in a first direction in which the nozzles are arrayed. The ribs are disposed in the filter unit at intervals corresponding in size to at least two of the separate chambers in the first direction to partition the filter unit. The inlet portions are communicated in the first direction with each other in at least one portion of each of the inlet portions facing the filter unit.

摘要： An ink-jet printing method includes the steps of dividing multiple ink droplet discharging pulses into two or more groups in an ink droplet discharging order, providing the multiple ink droplet discharging pulses to a pressure generator per scan line time, and discharging ink droplets from an ink droplet discharge head in accordance with the multiple ink droplet discharging pulses. The method further includes the steps of combining ink droplets of a former group as a first combined ink droplet, combining ink droplets of a latter group as a second combination droplet, combining the second combined ink droplet of the latter group with that of former group before the ink droplets reach a target, and maintaining a prescribed amount of ink droplets landing on the target by decreasing the number of ink droplet discharging pulses.

摘要： An inkjet recording head includes a nozzle plate, chamber plate, and a diaphragm plate. The nozzle plate includes a plurality of nozzles for ejecting ink droplets, a plurality of connecting channels in communication with the nozzles and pressure chambers. The nozzles are formed in a row at a uniform pitch. The connecting channels extend from the nozzles alternately in opposite directions in a staggered formation and are offset a prescribed angle to a direction orthogonal to the row of nozzles. The chamber plate includes the pressure chambers, restrictors, and common ink chambers formed therein. Each pressure chamber has an elongated shape extending in a direction orthogonal to the row of nozzles. The pressure chambers are formed in rows, one on either side of the row of nozzles, so that the pressure chambers in one row oppose the corresponding pressure chambers in the other row. The diaphragm plate has a vibration plate that seals the pressure chambers.
