摘要： A recording head 200 has a plurality of nozzle orifices aligned in a row extending in a first direction. The recording head 200 is arranged with the nozzle orifices in confrontation with a recording medium P. The recording medium P is moved in a second direction B with respect to the recording head 200. Also, ink droplets ejected from the nozzle orifices are charged to a charged amount that corresponds to deflection amount of the ink droplets. The charged ink droplets are deflected in a direction perpendicular to a main scanning line. The plurality of ink droplets ejected from the plurality of nozzle orifices impinge on the same pixel position or at a nearby position so that it is possible to impinge multiple droplets at the same pixel position or a nearby position. As a result, it is possible to back up broken nozzles and to reduce recording distortion.

摘要： An orifice electrode/ink receiving member 11 is attached to an orifice plate 13 that is attached to a recording head module 10. An ink absorbing member 111 is embedded in a lower surface of the orifice electrode/ink receiving member 11. A recording ink droplet 14 ejected through an orifice 12 is deflected as needed by an angled electric field 85 and then impinges on a recording sheet 60 to form a recording dot 70. On the other hand, a refresh ink droplet 15 is deflected by the angled electric field 85 and impinges on the ink absorbing member 111 of the orifice electrode/ink receiving member 11 after flying in a U-turn path. In this configuration, the ink absorbing member 111 provided to the orifice electrode/ink receiving member 11 collects ink, so that there is no need to increase a gap between the recording head module 10 and the recording sheet 60 so much in order to dispose the ink absorbing member 111, preventing decrease in recording precision and paper jam. Also, it is possible to perform the ink refresh operation using a minimum amount of ink anytime needed without stopping recording operations.

摘要： When positively charged ink droplets 608 from a defective nozzle impact a negatively charged deflector electrode 320, the positive charge on condenser 609 flows to the ground via a FET 618 of a photo-coupler 610. As a result, the electric discharge occurs by an amount equivalent to the charging amount of the ink droplets 608 clinging on the electrode 320. Because a switching signal 606 is “1”, the ON resistance of the photo-coupler 610 is large, and the ON resistance of the FET 620 of the photo-coupler 612 is small. Accordingly, the discharge due to the charged ink droplets 608 is detected as a large detection voltage and amplified by an operational amplifier 613 . Because the charger voltage of the condenser 609 is static and has no noise, even when the detection output 615 is highly amplified, noise during the detection is suppressed.
摘要翻译：当来自有缺陷的喷嘴的带正电的墨滴608撞击带负电的偏转器电极320时，电容器609上的正电荷经由光电耦合器610的FET618流到地。结果，放电发生量相当于粘附在电极320上的墨滴608的充电量。由于切换信号606为“1”，因此光电耦合器610的导通电阻大，光电耦合器610的FET620的导通电阻，耦合器612很小。因此，由于充电的墨滴608引起的放电被检测为大的检测电压并由运算放大器613放大。由于冷凝器609的充电器电压是静态的并且没有噪声，所以即使当检测输出615高度放大时，也可以抑制检测期间的噪声。

摘要： As shown in FIG. 7(e), an electric field is generated at timing T3 at which an ink droplet 14 is divided, end moves the negative ions toward a main ink portion 14m. As shown in FIG. 7(e′), a resultant main ink droplet 14M has an increased charging amount of −3 q, and a satellite ink droplet 14S has a decreased charging amount of −6 q. When the main ink droplet 14M and the satellite ink droplet 14S have the mass of 1 m and Qs, respectively, then the relative charging amounts of the main ink droplet 14M and the satellite ink droplet 14S are both −3. Hence, the deflection amount of the satellite ink droplet 14S is approximately equal to the deflection amount of the main ink droplet 14M. Accordingly, the satellite ink droplet 14S and the rain ink droplet 14M impact the recording sheet 60 on the same spot or on the extremely close spots, thereby forming a single dot.
摘要翻译：如图所示。如图7（e）所示，在分配墨滴14的定时T3产生电场，使负离子向主墨部14m移动。如图所示。如图7（e'）所示，得到的主墨滴14M的充电量为-3q增加，卫星墨滴14S的充电量为-6q减少。当主墨滴14M和卫星墨滴14S的质量分别为1m和Qs时，主墨滴14M和卫星墨滴14S的相对充电量均为-3。因此，卫星墨滴14S的偏转量近似等于主墨滴14M的偏转量。因此，卫星墨滴14S和雨墨滴14M在同一点或非常接近的位置撞击记录片60，形成一个点。

摘要： An ink jet recording device 1 includes a plurality of head modules 101 each formed with a plurality of nozzles. The ink jet recording device 1 prints a test pattern using the all nozzle of the head modules 101. Precise positions of dots forming the test pattern are detected, based on which positional shifts of the head modules 101 are calculated. The deflection amount and ink ejection timing for each head module 101 are changed based on the detected positional shift. In this manner, positional shifts of the assembled head modules 101 are electrically corrected without mechanically changing the physical positions of the head modules 101.

摘要： A laser beam printer is provided which is capable of compensating for the difference in diameter between dots every colors and preventing unintentional coloring of the boundary between colors. In a conventional light source used for a printer, a spot diameter thereof is small upon low output and large upon high output. However, in a semiconductor laser device of the present invention, which is used for a light source for a printer, the spot diameter of the light source is controlled so as to be large upon low output and small upon high output. It is thus possible to keep the spot diameter of the laser light source constant. As a result, an irregular color-free laser beam printer can be materialized.

摘要： An electrophotographic color printer exposes a photosensitive body to form an exposure pattern thereon. Toner material of two different colors is then applied to the exposure pattern by developers. The toner materials are subsequently transferred to a recording medium and fixed thereon. The toner materials are applied to the photosensitive body so that each of the two colors of toner materials have regions of two different thicknesses so they will have different thicknesses when applied to the recording medium. When two of the thicker regions are adjacent, the fixing of the toner materials will cause the toner materials of the two regions to mix. Thus, if the two adjacent thicker regions are of different colors, a third color will be produced. Toner material of further colors may also be transferred to the recording medium, by applying further toner materials to the same or another photosensitive body using further developers. The exposure pattern has a plurality of voltage levels having predetermined relationships to one another.
