Abstract
It is an object of the invention to achieve a liquid ejection control method and the like that allows the amount of consumed liquid to be reduced. The liquid ejection control method controls the ejection of liquid, from nozzles for ejecting liquid, onto a medium that is fed in a predetermined feed direction, and has a step of detecting a portion of the medium that is positioned on an upstream side in said feed direction, and a step of not ejecting liquid from nozzles of a plurality of nozzles that are located on the upstream side in the feed direction based on the results of the detection.
Claims9
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.
