Abstract
The liquid ejecting heads are arranged on the head carrying member such that each pair of nozzles that are next to each other in terms of first-direction positions of adjacent ones of the liquid ejecting heads are shifted relative to each other by an offset length δ corresponding to a relative displacement in the first direction between the liquid ejecting heads due to thermal expansion during liquid ejection with reference to a specified pitch at which nozzles included in a single nozzle row are provided.
Claims3
A liquid ejecting apparatus comprising:
- a head unit in which a plurality of liquid ejecting heads are provided in a first direction on a head carrying member, the liquid ejecting heads each having a nozzle group including a plurality of nozzles from which liquid is ejected toward an object of liquid ejection, the nozzles being lined in the first direction at a specific pitch, the head unit being configured to eject the liquid from the nozzles while moving in a second direction crossing the first direction relative to the object of liquid ejection,
- wherein the liquid ejecting heads are arranged on the head carrying member such that each pair of nozzles that are next to each other in terms of first-direction positions of adjacent ones of the liquid ejecting heads are shifted relative to each other by an offset length δ corresponding to a relative displacement in the first direction between the liquid ejecting heads due to thermal expansion during liquid ejection with reference to a specified pitch at which nozzles included in a single nozzle row are provided.
