<P>PROBLEM TO BE SOLVED: To accurately detect a pattern for an ejection inspection by eliminating influence, for example, of an error of mounting of a sensor. <P>SOLUTION: The ejection inspecting device is equipped with a plurality of ink ejection parts for performing recording on a medium by using ink, and the sensor for detecting the pattern which is formed by the ink ejection parts. The ejection inspection for the ink ejection parts is performed according to the result of detection by the sensor when a detecting position of the sensor and the pattern for the inspection are relatively moved in the first direction. Before the ejection inspection, the ink ejection parts form a pattern for adjustment on the medium; the detecting position of the sensor and the pattern for the adjustment are relatively moved in the second direction; and a second-direction adjusted value is acquired according to the result of the detection by the sensor in this case. The ink ejection parts form the pattern for the adjustment on the medium. The detecting position of the sensor and the pattern for the adjustment are relatively moved in the first direction, and a first-direction adjusted value is acquired according to the result of the detection by the sensor in this case. The ejection inspection is performed by means of the acquired first-direction and second-direction adjusted values. Relative movement speeds of the detecting position of the sensor and the pattern for the adjustment when the second adjusted value is acquired are lower than relative movement speeds when the first adjusted value is acquired. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
