Abstract:
1. A liquid ejection apparatus for ejecting liquid onto a medium, comprising: a plurality of nozzles, arranged in a predetermined feed direction, for ejecting liquid; a movable ejection head provided with said plurality of nozzles; a feed mechanism for feeding the medium in said feed direction; and a controller which, detects a portion of said medium that is positioned on an upstream side in said feed direction; and makes a nozzle located most upstream in said feed direction, and nozzles within a predetermined distance in the feed direction from the most upstream nozzle, not eject liquid based on a result of said detection, wherein said predetermined distance is increased in correspondence with an increase of an aggregate paper feed amount of said medium after said portion of said medium that is positioned on the upstream side in said feed direction has been detected; wherein the paper feed amount of said medium is increased after said portion of said medium that is positioned on the upstream side in said feed direction has been detected; and wherein said predetermined distance is an amount obtained by subtracting a predetermined amount from said aggregate paper feed amount.
