Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To enhance reliability in the measurement of liquid drop ejection characteristics by measuring the position of a liquid drop in the images picked up for a plurality of liquid drops being ejected from a nozzle hole and making a decision whether the liquid drop ejecting position is stabilized or not based on the measurements.

Subsequently, the image in a window W2 is fetched and a decision is made whether the image of the ink drop 5 is present or not in each window W2. If the image of the ink drop 5 is present in both windows W2, fluctuation in the measurement of ink drop position is calculated in the longitudinal and lateral directions and a decision is made whether the fluctuation falls within a preset allowance or not in each direction. A decision is made that ejection of ink drop is stabilized if the fluctuation falls within a preset allowance in each direction otherwise remeasurement is discussed.

In such a case, a switching pawl 12 is switched to a direction where the advance of the paper is not prevented. The leading edge of the paper, especially, a long paper, is guided to the vacant space of the both-side carrying part 15 from the backward lower part of a carrying roller 13. When the trailing edge of the paper is detected by a sensor(not shown by figure) set near the pawl 12, the roller 13 is stopped. Thereafter, the position of the pawl 12 is switched to invert the rotating direction of the roller 13. The recording paper is switched back and fed in the both-side carrying part 15 through a carrying roller 14.
