摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer are provided for faithfully performing various image representations through ink droplet ejection driving signals of different waveforms. Based on a waveform selection signal from a selection controller, a waveform selector selects one of a plurality of drive signals from a drive waveform generator in a time-division manner. The selected signal is supplied to a piezoelectric element of a corresponding nozzle. Control is thereby performed on ink droplet ejection with a drive signal having a temporally varying waveform. The drive signals include a signal having a varying voltage waveform that disables ink droplet ejection in isolation from another waveform. A new composite drive signal waveform is generated by time-divisional selection not only at a point between ejection cycles but also at a point during the ejection cycle.

摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of an ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.

摘要： An ink-jet printer and a drive method for driving a recording head of an ink-jet printer are provided for controlling a size and a velocity of an ejected ink droplet. The ink-jet printer includes a droplet outlet orifice through which an ink droplet is ejected, an ink chamber communicating with the outlet orifice, an ink feed duct for feeding ink to the ink chamber, and a piezoelectric element for expanding and contracting the ink chamber in response to an applied voltage. A process for ink ejection includes a first step in which a meniscus in the outlet orifice is retracted towards the ink chamber by expanding the ink chamber, a second step in which the meniscus is moved towards the orifice by filling the chamber with ink, and a third step in which an ink droplet is ejected by contracting the ink chamber. The size and the velocity of the ink droplet ejected in the third step are controlled by controlling a position and a velocity of periodic travel of the meniscus at a start point of the third step.

摘要： The present invention provides an apparatus for discharging liquid in which nozzles (31) allocated to head chips (25) are so arranged as to overlap at parts of adjacent head chips (25), and the distance Ls between nozzles of adjacent head chips of the same color is set to be even number pitches, while the distance Ld between nozzles of head chips of different color is set to be even number pitches. Thus, tiling part can be printed in the hound's tooth manner in driving line heads employing tiling which has overlapped parts formed therein under time division drive. The problem that coloring of superposed colors at overlapped parts becomes different from that at non-overlapped parts can be prevented.

摘要： The liquid discharge apparatus including a head having liquid dischargers capable of deflecting the trajectories of discharged droplets in a plurality of directions. At least two of the liquid dischargers neighboring each other are capable of discharging droplets in the same pixel area. When there is a shut-off liquid discharge due to droplet discharge failure, this information is stored. According to the stored information, the discharge signal corresponding to the droplets the shut-off discharger were supposed to discharge is transferred to another liquid discharger in the vicinity of the shut-off discharger. This other liquid discharger alternatively discharges droplets so that the droplets land in a position the droplets would have had landed if they were discharged by the shut-off discharger.
