LIQUID EJECTION APPARATUS, LIQUID EJECTION SYSTEM, AND LIQUID EJECTION METHOD
First Claim
1. A liquid ejection apparatus, comprising:
- a plurality of liquid ejection head units that are configured to eject liquid onto a conveyed object at different positions along a conveying path for conveying the conveyed object;
a first support member that is provided upstream of a landing position of the liquid ejected onto the conveyed object by a corresponding liquid ejection head unit of the plurality of liquid ejection head units;
a second support member that is provided downstream of the landing position of the corresponding liquid ejection head unit;
a detection unit that is installed between the first support member and the second support member for the corresponding liquid ejection head unit and is configured to output a detection result indicating a position of the conveyed object with respect to an orthogonal direction that is orthogonal to a conveying direction of the conveyed object; and
a moving unit configured to move the each liquid ejection head unit of the plurality of liquid ejection head units based on the detection result.
