    • PROBLEM TO BE SOLVED: To realize image formation with respect to an entire printing medium while avoiding occurrence of a reduction in image quality in association with damage of components and discharge destabilization.SOLUTION: A printer comprises: a first head for forming a first dot group; and a second head for forming a second dot group. The first head has a first nozzle array for first chromatic color ink and a second nozzle array for second chromatic color ink. The second head has a third nozzle array for the first chromatic color ink and a fourth nozzle array for the second chromatic color ink. In a case where a number of dots constituting dot arrays that are formed by ink ejection executed between a sub-scanning and a subsequent sub-scanning and are arranged side by side in a main scanning direction for at least one of the first chromatic color ink and the second chromatic color ink is 3500 or more, rational numbers represented by a number of dots included in the first dot group and a number of dots included in the second dot group in the dot arrays are values other than zero.
    • 要解决的问题:相对于整个打印介质实现图像形成,同时避免与组件的损坏和排出不稳定相关联的图像质量的降低的发生。解决方案:打印机包括:用于形成第一点组的第一头 ; 以及用于形成第二点组的第二头部。 第一头部具有用于第一彩色墨水的第一喷嘴阵列和用于第二彩色墨水的第二喷嘴阵列。 第二头具有用于第一彩色墨的第三喷嘴阵列和用于第二彩色墨的第四喷嘴阵列。 在构成通过在副扫描和后续副扫描之间执行的喷墨形成的点阵列的多个点在主扫描方向并排布置的第一彩色墨水中的至少一个的情况下 并且第二彩色墨水为3500以上时,包含在第一点组中的点数表示的有理数以及点阵列中的第二点组中包含的点数是除零以外的值。

    • PROBLEM TO BE SOLVED: To solve a problem that a temperature detector must be added in a head driver IC when detecting temperature in an inkjet printer.SOLUTION: The printer includes a count section 851 for counting the number of signals for regulating a discharge period at which ink is discharged to one pixel from a nozzle, and a discharge control section 852 for controlling so that the ink is not discharged from the nozzle when the number of the signals counted by the count section 851 exceeds a predetermined threshold value and when it is determined that a communication result with a discharge data control section is abnormal.
    • 要解决的问题:为了解决当在喷墨打印机中检测温度时必须在头驱动器IC中添加温度检测器的问题。解决方案:打印机包括计数部分851,用于计数用于调节放电时间的信号的数量 哪个墨水从喷嘴排出到一个像素;以及排出控制部分852,用于当由计数部分851计数的信号数超过预定阈值时控制墨水不会从喷嘴排出,当它是 确定与排出数据控制部的通信结果异常。

    • PROBLEM TO BE SOLVED: To suppress an occurrence of a situation that a printing operation stops before completing an image formation on a medium regardless of a content of an image to be printed or a size of a printing medium.SOLUTION: A control unit of a printing apparatus controls a carriage to perform at least a first dot forming operation which forms first dots, an adjustment operation which does not include dot forming, and a second dot forming operation which forms second dots on a printing medium sequentially. When an image in which RGB values of each pixel are (0,0,0) is printed, a lowest-brightness region of the area in which the first dots are formed and a lowest-brightness region of the area in which the second dots are formed overlap in a first direction of main-scanning, and do not overlap in a direction of sub-scanning.
    • 要解决的问题:无论打印图像的内容或打印介质的尺寸如何,都可以抑制在完成介质上的图像形成之前打印操作停止的情况。解决方案: 打印装置控制滑架以进行形成第一点的至少第一点形成操作,不包括点形成的调整操作和在打印介质上顺序形成第二点的第二点形成操作。 当打印出每个像素的RGB值为(0,0,0)的图像时,形成第一点的区域的最低亮度区域和其中第二点的最低亮度区域 在主扫描的第一方向上形成重叠,并且在副扫描方向上不重叠。
