Abstract
A method for setting up a condition for a drive signal in a liquid ejection head that includes a plurality of linearly-arranged nozzles and driving elements provided for each of the nozzles, includes: calculating an average value or a median value of ejection rates for each nozzle relating to a supply of the drive signal under a plurality of conditions; classifying the plurality of nozzles into a plurality of groups based on the average value or the median value of the ejection rates; calculating a proper condition for the drive signal corresponding to each group based on a statistical value of the ejection rate relating to the group; and selecting one proper condition among proper conditions corresponding to the groups so as to set the selected proper condition for each nozzle.
