Abstract:
1. A fluid ejection device comprising: a head part having a plurality of nozzles, the plurality of the nozzles ejecting a fluid toward a recording medium in accordance with recording data while the recording medium is fed in a feed direction with respect to the head part, the plurality of the nozzles being aligned on the head part in the feed direction of the recording medium, the plurality of the nozzles further ejecting the fluid so that flushing of the plurality of the nozzles is carried out; and a controller configured to carry out the flushing of the plurality of the nozzles, the controller controlling the plurality of the nozzles to eject the fluid and carrying out the flushing under a first fluid ejection condition during a recording process in accordance with the recording data, all of the plurality of the nozzles of the head part being located upstream in the feed direction of the recording medium relative to a first recording initiating part of a first image that is formed on the recording medium under the first fluid ejection condition, the first recording initiating part of the first image being a downstream end of the first image in the feed direction of the recording medium, the controller controlling the plurality of the nozzles to eject the fluid and carrying out the flushing under a second fluid ejection condition in which ejection frequency of the fluid ejected from the plurality of the nozzles is greater than ejection frequency of the fluid ejected from the plurality of the nozzles under the first fluid ejection condition, or quantity of droplets of the fluid ejected from the plurality of the nozzles is greater than quantity of the droplets of the fluid ejected from the plurality of the nozzles under the first fluid ejection condition, at least one of the plurality of the nozzles of the head part being located downstream in the feed direction of the recording medium relative to the first recording initiation part of the first image during the recording process under the second fluid ejection condition.
