ABSTRACT:
Methods are provided for use in a printing device. One method includes allowing a printing fluid to flow from a fluid supply container to a fluid reservoir of a printhead assembly, then urging material from at least the fluid reservoir and the fluid supply container to a separating container, then preventing any further amount of the printing fluid from flowing from the fluid supply container while continuing to urge the material from at least the fluid reservoir to the separating container, then stopping the urging of the material from at least the fluid reservoir to the separating container, and then allowing the printing fluid to flow from the fluid supply container to the fluid reservoir.
