Determining method for determining whether ink was ejected or not, computer-readable medium, and printing apparatus |
摘要 |
A determining method and the like is achieved for determining more accurately whether or not ink has been ejected. A determining method for determining whether or not ink was ejected from a plurality of nozzles includes a step of printing a non-ejection print pattern, a step of obtaining an output value upon non-ejection that is output based on the light that has been emitted toward the non-ejection print pattern, a step of printing an all-ejection print pattern, a step of obtaining an output value upon ejection that is output based on the light emitted toward the all-ejection print pattern, a step of setting a threshold value between the output value upon non-ejection and the output value upon ejection, and a step of comparing the threshold value with an output value that is output from a light-receiving section based on the light that has been emitted toward the print patterns.
