Abstract: Example fluidic devices and methods are described. An example device includes a throughput chamber, an inlet to guide liquid in the throughput chamber and an outlet to guide liquid out of the throughput chamber. The example device also includes a rib that protrudes from a wall of the throughput chamber. The rib has a narrowed section in the throughput chamber between the inlet and the outlet to form a meniscus in the narrowed section.

Abstract: A fluid cartridge for a printing device includes a housing including a floor, a chamber defined in the housing and configured to store an ink therein, a capillary medium disposed in the housing and in operative communication with the chamber, and a wick disposed at least partially in an opening of the floor, the wick including a portion extending a predetermined distance into the housing such that the wick portion contacts the capillary medium. The fluid cartridge further includes an enriched pigment-confining member established inside the housing such that the confining member physically contacts the floor and surrounds at least a portion of a periphery of the wick. The confining member is configured to i) block enriched ink from the wick, and/or ii) dilute the enriched ink prior to flowing through the wick.

Abstract: A printing device includes a supply of colorant that is non-refillable from an end user perspective and that is at least substantially non-removable from the printing device from the end user perspective. The printing device also includes a printing mechanism that forms images on media using the supply of colorant.

Abstract: An ink delivery system having at least one off-axis ink supply container and an on-axis printhead assembly. The on-axis printhead assembly includes at least one reservoir and a corresponding standpipe separated by a particle filter. At least one tube connects the off-axis ink supply container to the on-axis printhead assembly. A first valve is configured to selectively open a flow path between the tube and the reservoir. A second valve is configured to selectively open a flow path between the standpipe and the tube.

Abstract: An ink cartridge configured to hold an ink includes a substantially hollow body including an inner space and a substantially continuous inner wall. An optical prism in the inner space is disposed at a predetermined distance from the continuous inner wall such that an ink pocket is defined by a prism wall and the continuous inner wall. The prism includes at least one reflection site formed at an angle configured to reflect light from a light source through the prism at a predetermined height relative to a bottom of the body. If ink is present in the ink pocket at a level below at least a portion of the reflection site, the ink does not block the light reflected off of the portion of the reflection site from traveling across the ink pocket at the predetermined height, such that the reflected light is externally detectable by electronic means.

Abstract: A sealing component includes an elastomeric material. An exterior side surface of the elastomeric material is to define at least a first seal with a first external mating member into which the sealing component is insertable. An interior surface of the elastomeric material is to define a second seal and a third seal with a second external mating member insertable into the sealing component.

Abstract: Methods of creating an internal channel of a fluid-ejection device are provided. One method includes encapsulating a channel core in an element of the fluid-ejection device that corresponds to the internal channel and dissolving at least a portion of the channel core.
