摘要： In a structure in which a printing medium is subjected to a maintenance ejection in order to maintain a favorable ink ejection performance of a printing head, dots formed on the printing medium by the maintenance ejection have a reduced visibility. Specifically, an area of dots formed by landing ink droplets ejected from the printing head for the maintenance ejection onto the printing medium is smaller than an area of similar dots formed by a normal printing. Specifically, by flowing currents having different waveforms into an ejection heater of the printing head depending on the ejection for printing an image and the maintenance ejection, an area of dots formed by the maintenance ejection can be smaller than an area of dots formed by the normal ejection for printing an image.

摘要： Problems, which occur when printing is performed on the surface of a rotating disk using by using a print head arranged in the outer circumferential direction from the center of rotation, are resolved. Light emitting sections performs exposure in synchronism with rotational driving for rotating a medium, and pixels which are adjacent in the circumferential direction of rotation are exposed in a partially superimposed fashion by making the amount of movement in the circumferential direction along which the outermost circumference of the medium moves between exposures smaller than the width in the circumferential direction of the pixels formed by exposure. In a plurality of light emitting sections provided in an optical unit, the quantity of light for exposing a pixel on the inner circumferential side in the radial direction is set to be smaller than the quantity of light for exposing a pixel on the outer circumferential side in the radial direction for the respective exposure positions for the medium. Therefore, difference in the tonal shading caused by superposition is reduced by lowering the density created by each exposure in respect of the pixels on the inner circumferential side in the radial direction where there is a large overlap between exposures.
摘要翻译：解决了通过使用从旋转中心沿外周方向排列的打印头在旋转盘的表面上进行打印时发生的问题。发光部分与用于旋转介质的旋转驱动同步地进行曝光，并且沿圆周方向相邻的像素以部分叠加的方式曝光，通过使沿周向的最外周的移动量介质在曝光之间移动，小于通过曝光形成的像素的圆周方向上的宽度。在设置在光学单元中的多个发光部中，将用于使径向内周侧的像素曝光的光量设定为小于使外周侧的像素曝光的光量介质的各个曝光位置的径向方向。因此，通过降低曝光之间存在大的重叠的径向方向的内周侧上的像素的每次曝光产生的密度，可以降低叠加引起的色调阴影的差异。

摘要： In a liquid discharge detection method and apparatus which detect a liquid discharged from a liquid discharge head, an electrode is placed at a position where the liquid discharged from the liquid discharge head comes into contact with the electrode while being in contact with the head. When a liquid is discharged, and the head is connected to the electrode through the liquid, the circuit becomes a closed circuit. A voltage generated between the two ends of a resistor is obtained from a current flowing in the closed circuit. When this voltage becomes equal to or higher than a predetermined voltage, liquid discharge can be detected.
