摘要： With a recording head (200) having a plurality of nozzle holes arranged in a row in a first direction disposed so that the nozzle holes face a recording element (P), the recording element (P) is moved for main scanning in a second direction (B) with respect to the recording head (200). Ink particles jetted from the nozzle holes are charged to a charging level corresponding to the deflection distance of the ink particles, and the charged ink particles are deflected in a direction perpendicular to the main scanning line. In addition, a plurality of ink particles jetted from the plurality of nozzle holes are allowed to strike the same pixel position or a portion in the vicinity thereof to enable multiple-striking to the same pixel position or a portion in the vicinity thereof, thereby easing back-up for failed nozzles and uneven recording.

摘要： In a printer device, when an electric field causing a cohesion region (220) is applied at the top ends of discharge electrodes (11a), a spherical shaped pigment aggregate (1) flies out from the top end of the discharge electrode (11a), wherein although ink discharge cycle is comparatively long, but no excess charged pigment particles fly out from the top end of the discharge electrode (11a), fine pixels can be formed on a recording medium. When an electric field causing a condensation region (222) is applied at the top ends of the discharge electrodes (11a), a semispherical shaped or thick shell shaped pigment aggregate (190) flies out from the top end of the discharge electrode (11a), wherein since ink solvent containing the charged pigment particles flies out together with the semispherical shaped or thick shell shaped pigment aggregate (190), higher density pixels than that by the cohesion region (220) can be recorded with a high speed, thus the condensation region (222) is suitable for a solid print recording, thereby the printer device can achieve a highly accurate and fine and a high gradation recording at a high speed.
摘要翻译：在打印机装置中，当在放电电极（11a）的顶端施加引起粘合区域（220）的电场时，球形的颜料聚集体（1）从放电电极（11a）的顶端飞出，其中尽管喷墨周期比较长，但是没有过量的带电颜料颗粒从放电电极（11a）的顶端飞出，可以在记录介质上形成精细的像素。当在放电电极（11a）的顶端施加引起冷凝区域（222）的电场时，半球形或厚壳形颜料聚集体（190）从放电电极（11a）的顶端飞出，其中，由于含有带电颜料颗粒的油墨溶剂与半球形或厚壳形颜料聚集体（190）一起飞出，因此可以高速记录比内聚区域（220）更高的密度像素，因此冷凝区域222适用于实心打印记录，由此打印机装置可以高速实现高精度和精细以及高灰度等级记录。

摘要： 57 An ink jet printer feeds recording paper by a predetermined distance DT each time a plurality of dot line data have been printed, by a printing head (4), for every line. The printing head (4) has n printing elements (11A to 11D) arranged in a line in the first direction at predetermined regular intervals of P, and prints the dots with a dot pitch of PC, in the first direction. The printing operation is executed so as to satisfy the expression of P = n x PC + PC = DT + PC.
