摘要： In an inkjet printing apparatus utilizing an inkjet head and an ink tank for supplying ink to the same, it is made possible to suppress any reduction in image quality attributable to changes in physical and chemical properties of the ink that occur during an elapsed time from the manufacture of the ink tank to the use of the same, thereby allowing images to be formed with high reliability and stability at a low running cost. The apparatus has a discharging unit for discharging the ink through a nozzle at the head and an ink detecting unit for detecting the consumption of the ink in the ink tank. The detected ink consumption is compared with a threshold for ink consumption appropriately determined based on the elapsed time, and control is performed such that the amount discharged by the discharging unit is increased when the ink has not been consumed sufficiently.

摘要： Provided is a print position control method whereby displacement of a print position in a wide range can be corrected very accurately, without reducing a printing speed or increasing a manufacturing cost. Thus, a printing apparatus includes: a first correction unit, for correcting a print position at accuracy equal to the resolution of the printing apparatus; and a second correction unit, for correcting the print position at accuracy higher than the resolution and in the range of an area that corresponds to one pixel of the resolution. With this arrangement, the print position displacement in a wide range equal to or greater than one pixel can be corrected by the first correction unit, and a print position displacement smaller than one pixel can be corrected by the second correction unit. Therefore, correction of a print position displacement in a wide range is enabled at a higher accuracy.
摘要翻译：提供一种打印位置控制方法，可以在不降低打印速度或增加制造成本的情况下，非常精确地校正大范围内的打印位置的位移。因此，打印设备包括：第一校正单元，用于以与打印设备的分辨率相等的精度校正打印位置; 以及第二校正单元，用于以高于分辨率的精度和对应于分辨率的一个像素的区域的范围来校正打印位置。利用这种布置，可以通过第一校正单元来校正等于或大于一个像素的宽范围内的打印位置位移，并且可以通过第二校正单元校正小于一个像素的打印位置位移。因此，可以更高精度地进行宽范围内的打印位置位移的校正。

摘要： Image deterioration is suppressed as much as possible which is complexly generated by variations of printing positions respectively of printing elements in a printing element row and by displacement of printing positions among printing element rows. To this end, a first adjustment value for adjusting printing positions among a plurality of printing elements included in a printing element row is obtained. Next, printing positions among a plurality of printing elements are adjusted based on the first adjustment value. Then a second adjustment value for adjusting printing positions among not less than two of the printing element rows is obtained. Thereby variations of printing positions in a discharge port row and displacement of printing positions among discharge port rows are properly adjusted in different phases, and adverse effects generated by two kinds of different causes are collectively suppressed.

摘要： A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.

摘要： There is provided a printing apparatus capable of printing input data in proper adaptation to plural types of printing data input units and environments of use. For this purpose, the type of an input unit is first recognized. For example, when it is recognized that a personal computer capable of causing the printing apparatus to perform a setting process for registration is connected, it is judged that the process has already been performed, and a mode for printing at a high speed is adopted. When it is recognized that a digital camera is connected, since it is likely that the process has not been performed yet, a mode for printing at a low speed is adopted to prevent any reduction in image quality.
