摘要： An inspective ejection method using inspective injection data, including unit ejection data and non-ejection data, for causing fluid to be ejected from nozzle orifices of a fluid ejection apparatus. The unit ejection data is used for individually inspecting each of a group of continuous nozzle orifices of a predetermined number M, less than total number Q. The non-ejection data having a length of at least Q−M is continuously added to a leading or trailing side in a unit ejection data reading direction. A transfer start address is selected in the area of the inspective ejection data at an interval of M, while avoiding duplication of the transfer start address. The inspective ejection data is transferred to an ejection driving unit, starting from the selected transfer start address. The selecting transferring steps are repeated a whole number of times that is Q/M or greater, while changing the transfer start address.
