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 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: An image forming apparatus and method for determining a toner level and providing a notification are provided. The method of operating an image forming apparatus includes counting a number of times a lower toner hopper receives toner from an in-situ refillable upper toner hopper, calculating an estimate of toner volume transferred from the lower toner hopper to a surface of a photosensitive drum, determining an amount of toner consumed from the in-situ refillable upper toner hopper based on the number of times the lower toner hopper receives toner from the in-situ refillable upper toner hopper and the estimate of toner volume transferred from the lower toner hopper to the surface of the photosensitive drum, and generating an upper toner hopper refill notification when the amount of toner consumed from the in-situ refillable upper toner hopper is determined to exceed a threshold value.

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: Examples described herein relate to a print particle refill device consistent with the disclosure. For instance, a print particle refill device may comprise a cap disk to form a barrier between the print particle refill device and a receptacle, a first liner adjacent to the cap disk to seal print particles in the print particle refill device, and an actuating liner to wipe print particles, when present, from the receptacle.
