摘要： An adjustment pattern, which is composed of a reference pattern made of plural independent liquid droplets and a pattern to be measured made of plural independent liquid droplets ejected under an ejection condition different from the reference pattern, is formed on a water-repellent conveying belt. Then, light is applied to the adjustment pattern to receive the regular reflection light from the adjustment pattern, so that the adjustment pattern is scanned. The distance between the respective patterns is measured based on the measured result. Finally, liquid droplet ejection timing of the recording head is corrected based on the result thus measured.

摘要： A side wall surface of a carriage is disclosed with two first projection parts and a second projection part that define the inclination of a reflective optical sensor in its vertical direction. The two first projection parts are arranged at the same height position with a detection surface as a reference, and the second projection part is arranged at a position higher than the first projection parts with the detection surface as the reference. The second projection part has a first part higher in position from the side wall surface of the carriage than the first projection parts and has a second part lower in position than the first part. The second part has a screw hole into which a clamping member for fixing the reflective optical sensor to the second part is tightened.
