Abstract

A droplet deposition 10 head includes one or more manifold components 100, 50(a) and two or more arrays of fluid chambers, each array extending in an array direction 500. The head extends, in the ejection direction 505, from a first end, at which the one or more fluid inlets are located, to a second end, at which the arrays of fluid chambers are located. Two or more branched inlet paths 180 are provided within the manifold components, each of the branched paths being fluidically connected so as to receive fluid at a main branch 181 thereof from a respective one of the fluid inlets, branching at one or more branching points into two or more sub-branches 182(a), 182(b). A plurality of widening inlet chambers 55(a), 55(b) is provided within the manifold components, the width of each widening inlet chamber in the array direction increasing with distance in the ejection direction. Each of the branched inlet paths is fluidically connected so as to supply fluid to two or more of the widening inlet chambers. A sub-branch of one branched inlet path crosses a sub-branch of another inlet path, when viewed in the ejection direction.
