Abstract: Examples of a print particle transfer device are described herein. Some examples of the print particle transfer device include a print particle vessel to contain print particles. In some examples, the print particle transfer device also includes a plunger with a fibrous seal element to engage an inside surface of the print particle vessel. The fibrous seal element seals an interface between the plunger and the inside surface of the print particle vessel to prevent escape of the print particles at the interface during movement of the plunger within the print particle vessel.

Abstract: Examples of a print a print particle replenishment device are described. In some examples, a print particle replenishment device includes a rotating member to rotate about a central axis of the print particle replenishment device. In some examples, the rotating member includes an opening offset from the central axis. In some examples of a print particle replenishment device, a nozzle is offset from the central axis, where the nozzle is to slide with respect to an interior plane of the rotating member to align with the opening to transfer print particles through the nozzle and opening when in an open position. In some examples, a print particle replenishment device includes an extension that protrudes with respect to the opening to engage a port cover of a host device to move the port cover to open a port for replenishment at rotation.

Abstract: In some examples, a print material particles container (100) includes a print material reservoir (104), a structure (637) adapted to decrease a volume of the print material reservoir to output print material particles to an input of an imaging device, where the input of the imaging device is adapted to interface with an output interface of the print material particles container, and a metallic element (632) adapted to be in proximity with a sensor (736) when the volume adapting structure is moved from a first position (526) to a second position (528) to output the print material particles.

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: A digital pen systems and methods are provided. The digital pen comprises an internal pen module comprising a cartridge and a pressure sensor, a body housing the internal pen module, and a shuttle connected to the internal pen module on a first end of the digital pen and connected to a twist mechanism on a second end of the digital pen. The shuttle moves the cartridge and the pressure sensor when the twist mechanism is engaged.
