    • In a print head having arrays of large nozzles and small nozzles with different ink ejection volumes that are connected to a common ink chamber, the preliminary ejection operation is performed 29,000 times first on only the large nozzles at an ejection frequency of 10 kHz to discharge viscous or mixed color ink from ink chambers. After the preliminary ejection operation of the large nozzles is finished, only the small nozzles are made to perform the preliminary ejection operation 2,000 times at an ejection frequency of 10 kHz. Reducing the number of preliminary ejections from the small nozzles in this manner can minimize the generation of stray mist. Further, by performing the preliminary ejection operation on the large nozzles first, it is possible to discharge enough viscous ink from the ink chamber.
    • 在具有连接到公共墨水室的具有不同喷墨量的大喷嘴阵列和小喷嘴的打印头中,首先仅在大喷嘴上以10kHz的喷射频率执行预先喷射操作29,000次以排出粘性 或来自墨水室的混合彩色墨水。 在大喷嘴的预喷射操作完成之后,仅使小喷嘴以10kHz的喷射频率进行2000次预喷射操作。 以这种方式从小喷嘴减少初步喷射的数量可以最小化杂散雾的产生。 此外,通过首先对大喷嘴进行预喷射操作,可以从墨室排出足够的粘性墨。

    • A generator apparatus can provide generated power fit for a connected battery, and even if a load voltage is not within a suitable range, when the load voltage is a certain level or more, the generator can provide power. A selector 25 selects a target voltage for controlling the output voltage of a rectifier 2. An output controller 34 controls the rectifier 2 according to the target. A load judgment section 35 judges the terminal voltage of a battery 19. When the terminal voltage is within an allowable range with respect to the target value, permission for output is given to the output controller 34. When the load voltage is not within the allowable range, an alarm is raised. Even when the alarm is raised, if a load voltage develops which is not less than a predetermined voltage lower than the allowable range, the battery 19 can be charged by forced-output.
    • 发电机装置可以为连接的电池提供产生的电力配合,并且即使负载电压不在适当的范围内,当负载电压在一定水平以上时,发电机也可以提供电力。 选择器25选择用于控制整流器2的输出电压的目标电压。 输出控制器34根据目标控制整流器2。 负载判定部35判断电池19的端子电压。 当端子电压在相对于目标值的允许范围内时,输出许可被给予输出控制器34。 当负载电压不在容许范围内时,会发出报警。 即使在报警提高的情况下,如果产生不低于允许范围的预定电压的负载电压,则可以通过强制输出来对电池19进行充电。

    • A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.
    • 以黑色图像和彩色图像之间的边界处可能出现的颜色减少,印刷出高质量的图像。 用于喷射黑色墨水的头部和用于喷射彩色墨水的头部进行三次扫描,同时在其间进行输送以将打印介质移动到布置在头部上的四个喷射开口的间距,使得不同的喷射口对应于扫描 区域,其对应于四个间距,并且执行多遍打印以在该区域上完成打印。 黑色头完成黑色图像的打印,然后彩色头完成与黑色图像相邻的彩色图像的打印。 确定喷射口的布置,使得在完成黑色图像的打印的最后扫描和彩色图像的打印的第一次扫描之间,不存在执行打印的扫描。
