Abstract
A liquid ejection apparatus, a liquid ejection system, and a liquid ejection method are achieved which allow starting and ending positions for ejecting liquid to be set appropriately. A controller is provided which executes position determination control for determining at least one of the starting position and the ending position for ejecting liquid from a moving ejection head onto a medium that is fed by a feed mechanism, wherein the position determination control by the controller differs for when ejecting the liquid from the ejection head to a region within a predetermined range from a front edge or a rear edge, in a feed direction, of the medium, and for when ejecting the liquid from the ejection head to a central region, in the feed direction, of the medium.
Claims15
A liquid ejection apparatus for ejecting liquid, comprising:
- a movable ejection head for ejecting liquid;
- a feed mechanism for feeding a medium;
- a sensor for detecting a position of an edge of said medium;
- and
- a controller for executing position determination control for determining at least one of a starting position and an ending position for ejecting the liquid from said moving ejection head onto said medium that is fed by said feed mechanism,
- wherein said position determination control by said controller differs for when ejecting the liquid from said ejection head to a region within a predetermined range from a front edge or a rear edge, in a feed direction, of said medium, and for when ejecting the liquid from said ejection head to a central region, in said feed direction, of said medium.
A liquid ejection system, comprising:
- (a) a computer unit;
- and
- (b) a liquid ejection apparatus for ejecting liquid, said liquid ejection apparatus being provided with:
- a movable ejection head for ejecting liquid;
- a feed mechanism for feeding a medium;
- a sensor for detecting a position of an edge of said medium;
- and
- a controller for executing position determination control for determining at least one of a starting position and an ending position for ejecting the liquid from said moving ejection head onto said medium that is fed by said feed mechanism;
- wherein said position determination control by said controller differs for when ejecting the liquid from said ejection head to a region within a predetermined range from a front edge or a rear edge, in a feed direction, of said medium, and for when ejecting the liquid from said ejection head to a central region, in said feed direction, of said medium.
A liquid ejection method for ejecting liquid, comprising:
- a step of feeding a medium;
- a step of executing position determination control for determining at least one of a starting position and an ending position for ejecting liquid from a moving ejection head onto said medium that is fed;
- a step of starting ejection of the liquid from said ejection head at said starting position;
- and
- a step of ending ejection of the liquid from said ejection head at said ending position;
- wherein said position determination control differs for when ejecting the liquid from said ejection head to a region within a predetermined range from a front edge or a rear edge, in a feed direction, of said medium, and for when ejecting the liquid from said ejection head to a central region, in said feed direction, of said medium.
