    摘要： An ink jet printing apparatus is provided that can realize a stable ejection volume with the minimum change in a voltage value supplied in a scanning. To realize this, when a detected temperature of a print head is included in a first range, a pulse width control is performed while a voltage being fixed to a first voltage. When a detected temperature is included in a second range, a pulse width control is performed while a voltage being fixed to a second voltage. In the pulse width control based on the two voltages, a temperature partially overlapped region is provided between the first range and the second range. By this, even when a print head has an increased temperature during a print scanning, an ejection volume can be controlled, in the print scanning, while minimizing the switching of a driving voltage.

    摘要翻译： 提供一种能够以扫描中提供的电压值的最小变化实现稳定的喷射量的喷墨打印设备。 为了实现这一点，当打印头的检测温度被包括在第一范围内时，在电压被固定到第一电压的同时执行脉冲宽度控制。 当检测到的温度包括在第二范围内时，在电压被固定到第二电压的同时执行脉冲宽度控制。 在基于两个电压的脉冲宽度控制中，在第一范围和第二范围之间提供温度部分重叠的区域。 由此，即使打印头在打印扫描期间具有升高的温度，也可以在打印扫描中控制喷射量，同时最小化驱动电压的切换。

    摘要： A printing apparatus includes a print unit, an acquisition unit, and a setting unit. The print unit performs printing on a sheet by repeating reciprocating scans of a print head. The acquisition unit acquires information on a temperature of the print head. The setting unit sets a wait time to start a next scan after one scan. The setting unit increases the wait time by a predetermined additional time for each subsequent scan once a value acquired by the acquisition unit exceeds a first threshold, unless the value falls below a second threshold.

    摘要： An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.

    摘要： An inkjet printing apparatus, a maintenance method and an inkjet printing system which are capable of precisely calculating the amount of satellites or ink mist generated and replacing a collecting mechanism at most appropriate time. The inkjet printing apparatus has a wind-powered collecting mechanism collecting generated sub-droplets such as satellites or ink mist, and head temperature sensors for obtaining temperature information of the print head. The CPU calculates the amount of sub-droplets generated on the basis of printing conditions including the detected temperature information of the print head. The CPU determines whether the replacement of the wind-powered collecting mechanism is necessary on the basis of the calculated amount of sub-droplets generated.
