Abstract:
1. A liquid ejecting head comprising: a forward passage system configured to direct a forward flow of a liquid from an inlet opening to which the liquid is supplied from a liquid supply source to a plurality of liquid-droplet ejecting nozzles; a first filter and at least one second filter disposed in series with each other in the forward passage system to capture foreign matters contained in the liquid, wherein the first filter is located upstream of the at least one second filter in a direction of the forward flow of the liquid through the forward passage system, wherein the first filter comprises a first-upstream-side surface and a first-downstream-side surface in the direction of the forward flow, and wherein each of the at least one second filter comprises a second-upstream-side surface and a second-downstream-side surface in the direction of the forward flow; a first return passage system configured to direct a first flow of the liquid from the first-upstream-side surface to a first outlet opening from which the liquid is discharged without passing through the first filter, the first outlet opening being different from the inlet opening; and a second return passage system configured to direct a second flow of the liquid from the second-upstream-side surface to a second outlet opening from which the liquid is discharged without passing through the at least one second filter, the second outlet opening being different from the first outlet opening.
