    摘要: A nozzle testing device includes: a two-dimensional image sensor to capture an image of a pattern formed on a recording object by discharging ink from a nozzle row while moving the nozzle row and the recording object relative to each other in a direction orthogonal to the nozzle row; a light source unit provided such that regularly reflected light by the pattern forms a regular reflection area in the image of the pattern captured by the two-dimensional image sensor; and a detection unit to analyze the image to detect discharge failure of the nozzles. The regular reflection area is formed in the image such that a dimension in a direction corresponding to the direction of relative movement between the nozzle row and the recording object is greater than a dimension in a direction orthogonal to the direction corresponding to the direction of relative movement in the image.

    摘要: A conveying distance control device includes a conveying roller; a first detecting unit detecting rotational positions of the conveying roller; a line sensor sequentially detecting marks arranged on a test chart; a calculation unit, and a control unit. The calculation unit calculates a skew angle between a line passing through positions of a first mark and a second mark and a conveying direction of the conveying roller. The control unit obtains conveying distance errors indicating differences between corrected conveying distances not including errors caused by the skew angle and theoretical conveying distance of the marks in association with the rotational positions of the conveying roller, calculates a correction value for correcting a conveying distance of the conveying roller based on relationships between the conveying distance errors and the rotational positions of the conveying roller, and controls the conveying distance of the conveying roller based on the correction value.
