Abstract
A fluid dispenser may include an array of fluid delivery assemblies. Each fluid delivery assembly may include orifices through which fluid is to be ejected and slots. Each slot extends to a respective one of the orifices. The slots have different geometric shapes.
Claims19
A fluid dispenser comprising:
- an array of ejection dies, each ejection die comprising:
- orifices through which fluid is to be ejected;
- slots, each slot having a length and a width shorter than the length, each slot extending to a respective one of the orifices, wherein the slots have different geometric shapes, wherein the orifices are aligned in a plane and wherein the slots comprise a slot having a sidewall extending parallel to the length and perpendicular to the plane and a second opposite side wall extending parallel to the length and oblique to the plane.
A fluid delivery assembly comprising:
- a member through which slots extend to fluidic chambers,
- a thin film formed on and supported by the member opposite the fluidic chambers;
- actuators formed on the thin film within the fluidic chambers;
- and
- orifices through which fluid may be ejected from the fluidic chambers;
- and
- a manifold coupled to the member, the manifold comprising fluid passageways, wherein all of the fluid passageways of the manifold extending to the member are slanted in a single same direction, each of the fluid passageways connected to a respective one of the slots.

A fluid dispenser comprising:
- a bar,
- an array of staggered ejection dies supported by the bar, the array to collectively span a full width of print media, each of the fluid ejection dies comprising:
- a member through which slots extend to fluidic chambers, the slots comprising:
- a first slot having a sidewall perpendicular to the plane and a second opposite side wall oblique to the plane;
- a second slot having a first side wall extending at a first oblique angle relative to the plane and a second opposite side wall extending at the first oblique angle relative to the plane;
- a third slot having a first side wall extending oblique to the plane and a second opposite side wall having a first portion at a second oblique angle relative to the plane and a second portion at a third oblique angle relative to the plane, the third oblique angle being different than the first oblique angle;
- and
- a fourth slot having opposite side walls that mirror one another and that have multiple portions extending at different angles oblique to the plane;
- a thin film formed on supported by the member opposite the fluidic chambers;
- actuators formed on the thin film within the fluidic chambers;
- orifices through which fluid may be ejected from the fluidic chambers;
- and
- a manifold bonded to the member, the manifold comprising fluid passageways, each of the fluid passageways connected to a respective one of the slots.
