Liquid ejecting apparatus and method of circulating liquid

摘要

A liquid ejecting apparatus includes a storage unit which stores liquid, a head unit which ejects the liquid onto a medium, a plurality of supply flow paths which supplies the liquid to the head unit from the storage unit, a plurality of bypass flow paths which straddles the supply flow paths which are different from each other, and a controller which circulates the liquid in a circulating flow path which is configured only by the supply flow path and the bypass flow path among the storage unit, the head unit, the supply flow path, and the bypass flow path.

1. A liquid ejecting apparatus comprising:
a storage unit which stores liquid; a head unit which ejects the liquid onto a medium; three or more supply flow paths which supply the liquid to the head unit from the storage unit; a plurality of bypass flow paths which straddles the supply flow paths which are different from each other; and a controller which circulates the liquid in a closed-loop circulating flow path which is comprised of the supply flow path and the bypass flow path only, such that when circulating in the closed-loop circulating flow path, the liquid substantially only circulates in the supply path and the bypass path, wherein the closed-loop circulating flow path is configured such that the plurality of bypass flow paths does not straddle between the two supply flow paths with respect to any set of two supply flow paths among three or more supply flow paths.
