Abstract: Examples described herein relate to a supply valve consistent with the disclosure. For instance, a supply valve to supply print particles to a receptacle, the supply valve may comprise a print particle exit, a print particle entrance perpendicular to the print particle exit, and a liner adjacent to the print particle exit, where the liner is to wipe print particles, when present, from the supply valve responsive to the transition of the supply valve between a closed position and an open position.

Abstract: In some examples, a print materials container can include a dispense mechanism to dispense print materials directly to an in-situ reservoir of a printing device, a lock feature to engage a fill port during connection of the dispense mechanism to the fill port, and a valve integrated with the dispense mechanism for connecting the dispense mechanism to the fill port of the reservoir and comprising an output opening offset from a center axis of a tip of the dispense mechanism. The valve can open responsive to rotation of the valve opening with respect to the lock feature such that opposite openings align.

Abstract: Examples of an output assembly for a print particle replenishment device are described herein, Some examples of the output assembly include a sliding member. For example, the sliding member includes a channel that is offset from a rotating axis of the output assembly and a notch that is offset from the rotating axis and that extends to an outer edge of the sliding member. Some examples of the output assembly include a cover member to maintain a static position with respect to a rotation of the sliding member. In some examples, the cover member includes an alignment structure that is offset from the rotating axis of the output assembly.

Abstract: A refill dispenser for providing developer to a developer cartridge of an image forming apparatus is provided. The refill dispenser includes a container having a first section to accommodate developer and a second section including a source of pressure applied to the first section, a movable diaphragm interposed between the first section and the second section, and a valve coupled to the first section, wherein the pressure applied from the second section causes developer in the first section to be removed upon an opening of the valve
