Abstract: A printhead enables surface treatment fluid to be applied to the face of the printhead through at least one aperture located in the printhead faceplate. The printhead receives pressurized surface treatment fluid, which flows through a reservoir in the printhead, through at least one channel in the jet stack, and out the at least one aperture onto the surface of the faceplate. The surface treatment fluid is spread across ink apertures in the faceplate to disable ink from drooling from the ink apertures.

Abstract: An apparatus and method disclosed for delivering solid-ink pellets in an image-forming device comprises a hopper that houses solid-ink pellets. The hopper defines a vent and is provided with a mechanism to regulate the passage of the solid-ink pellets through the vent. A restrainer member configured to receive the solid-ink pellets defines a restrainer surface and a spreading arrangement to evenly spread the solid-ink pellets on its surface. Positioned below the vent, the restrainer retains the solid-ink pellets and is configured to transmit heat to solid-ink pellets causing them to melt evenly.

Abstract: The present disclosure provides apparatus and method for maintaining the flowability of solid-ink pellets in a system for delivering the pellets to an image-forming device. The apparatus includes a container storing the solid-ink pellets, and an extraction assembly for extracting the solid-ink pellets. The extraction assembly includes a tubular housing, extending from the bottom portion of the container, and an auger member rotatably placed within the tubular housing. The tubular housing receives the solid-ink pellets from the container and the auger member rotates to break up the obstructions to pellet flow.

Abstract: The present disclosure provides systems and methods for supplying solid-ink pellets from a container to a printing apparatus. The solid-ink pellets are held in a collapsible, hermetic bag, which is carried in the container. The bag is partially or fully transparent. A vacuum interface provides an access point to the bag. Further, a perforated nozzle, adapted to engage the vacuum interface, provides airflow within the bag and is configured to apply a suction force to extract solid-ink pellets from the bag.
