    Abstract: Fluid ejection devices with particle tolerant thin-film extensions are disclosed. An example apparatus includes a printer; a reservoir; and a printhead including: a firing chamber; a channel to receive fluid from the reservoir, the channel is coupled to the firing chamber, the channel having an opening; and a particle-tolerant film disposed adjacent the opening of the channel, the particle-tolerant film disposed between the channel and the reservoir, the particle-tolerant film to deter particles within the fluid from settling in an area adjacent the opening.

    Abstract: A fluid dispenser is disclosed herein. An example of such a fluid dispenser includes a member configured to define a plurality of orifices through which a fluid is ejected and a manifold including a plurality of fluid passageways each of which is configured to have a different angle relative to the member. This example of a fluid dispenser additionally includes a plurality of slots each of which is coupled to a different one of the fluid passageways of the manifold to conduct the fluid from the fluid passageways towards the orifices. Additional features and modifications of this fluid dispenser are disclosed herein, as are other examples of fluid dispensers.
