1. A liquid ejecting apparatus comprising:
a plurality of liquid ejecting heads comprising a plurality of ejection nozzles and configured to eject liquids of a plurality of colors respectively from the ejection nozzles; an image data storage device configured to store image data with respect to an image to be recorded on a recording medium; a mode receiving device configured to receive one image quality mode from at least two image quality modes as an image quality mode with respect to an image quality of the image to be recorded on the recording medium, the at least two image quality modes including a low image quality mode and a high image quality mode which has an image quality higher than an image quality of the low image quality mode; and a control device configured to:
control the plurality of liquid ejecting heads, based on the image data, to eject the liquids from the ejection nozzles of the plurality of liquid ejecting heads onto a plurality of image dot areas, among a plurality of dot areas defined on the recording medium, thereby forming image dots of the plurality of colors by the liquids landed on the plurality of image dot areas;generate a plurality of preliminary ejection data for the plurality of liquid ejecting heads respectively, the plurality of preliminary ejection data being related to preliminary ejections for recovering ejection performances of the plurality of liquid ejecting heads respectively; andcontrol the plurality of liquid ejecting heads, based on the plurality of preliminary ejection data generated for the plurality of liquid ejecting heads respectively, to perform the preliminary ejections, thereby forming flushing dots of the plurality of colors on a plurality of flushing dot areas among the plurality of dot areas, wherein in a case that the high image quality mode is received by the mode receiving device, the control device is configured to generate the plurality of preliminary ejection data, so that a ratio of the number of dot areas, on each of which one of the image dots as well as one of the flushing dots is formed, to the number of the flushing dot areas is higher than the ratio in a case that the low image quality mode is received by the mode receiving device.
