Patent ID: 8702189

Claim:
A liquid ejection apparatus comprising. at least one head each having an ejection face which has a plurality of ejection openings opened therein for ejecting liquid onto a recording medium, the at least one head comprising at least one first head having a first ejection face as the ejection face and the first ejection face having a plurality of first ejection openings formed therein as the plurality of ejection openings for ejecting recording liquid onto the recording medium; a convey belt which has a support region and at least one preliminary ejection region each provided on a face of the convey belt and which is configured to convey the recording medium in a conveying direction parallel to the ejection face by moving the face of the convey belt in a state in which the face faces the ejection face, wherein the support region is a region for supporting the recording medium, wherein the preliminary ejection region is a region onto which the liquid is ejected from the ejection openings in preliminary ejection, and wherein the preliminary ejection is ejection not contributing to image recording; and a controller configured to control the head and the convey belt; wherein the controller is configured to control the head and the convey belt on the basis of preliminary ejection data for the preliminary ejection such that, until a specific length of time has passed from a certain ejection of the recording liquid from one of the ejection openings onto the preliminary ejection region, a plurality of recording liquids ejected from one of the ejection openings in the preliminary ejection are landed on positions in the preliminary ejection region that do not overlap with each other, and such that, after the specific length of time has passed from the certain ejection of the recording liquid, each of at least one recording liquid ejected from the one of the ejection openings in a current ejection is landed onto a corresponding one of the plurality of recording liquids that landed the specific length of time before the current ejection of the at least one recording liquid, and wherein the controller is configured to control the head and the convey belt such that the plurality of recording liquids receives the recording liquid ejected from the one of the ejection openings the specific length of time after the certain ejection in order of length of time the plurality of recording liquids have been landed, starting with the greatest length of time.
