Abstract:
1. An inspective ejection method for causing a fluid to be ejected from nozzle orifices of a fluid ejection apparatus, the fluid ejection apparatus including an ejection unit having a plurality of the nozzle orifices capable of allowing the fluid to be ejected therethrough to a target, and an ejection driving unit that drives the ejection unit, the method comprising steps of: storing inspective ejection data in a memory, the inspective ejection data including: unit ejection data which is configured to shift a timing of ejection from each of the nozzle orifices to be inspected in one inspection period, the unit ejection data being used for individually inspecting each nozzle orifice belonging to a group of continuous nozzle orifices of a predetermined number M which is less than total number Q of the nozzle orifices; and non-ejection data having a length of at least Q−M and being added continuously to at least one of a leading side and a trailing side in a unit ejection data reading direction; selecting one transfer start address from among a plurality of transfer start addresses which are set in the area of the inspective ejection data at an interval of M, the selection being made in a manner to avoid duplication of the transfer start address; transferring to the ejection driving unit the inspective ejection data read from the memory starting from the selected transfer start address; and repeating the selecting step and the transferring step a plurality of times of a natural number which is Q/M or greater while changing the transfer start address.
