Abstract:
A liquid ejection apparatus includes a plurality of liquid ejection head units that eject liquid onto a conveyed object at different positions along a conveying path; a first support member and a second support member that are respectively provided at an upstream side and a downstream side of a landing position of liquid ejected by a corresponding liquid ejection head unit; a first detection unit that is installed between the first support member and the second support member and is configured to detect a position of the conveyed object in a direction orthogonal to a conveying direction of the conveyed object; a second detection unit that is installed upstream of the first detection unit; and a movement control unit that moves each liquid ejection head unit based on a plurality of detection results output by the first detection unit and/or the second detection unit.
