Examples of a host device that includes an input recess are described. In some examples, the input recess includes a rotating port cover offset from a central axis of the input recess. In some examples, the input recess includes a plurality of contacts disposed on an interfacing surface of the input recess to interface with a print particle replenishment device when the rotating port cover is rotated. In some examples, the plurality of contacts interfaces with a control device to authenticate the print particle replenishment device.

Examples of a print particle replenishment device for replenishing a host device are described herein. In some examples, the print particle replenishment device includes an output assembly to output print particles, comprising an interfacing portion. In some examples, the print particle replenishment device includes a plurality of contact pads disposed on an outer portion of the output assembly to rotate with the output assembly when opening a channel of the print particle replenishment device.

A printer includes a main body including a communicating portion, a development cartridge attachable to and detachable from the main body, the development cartridge to supply toner contained in a toner container to an electrostatic latent image formed on a photoconductor, to form a visible toner image, and a toner refilling portion connected to the toner container. The toner refilling portion includes a mounting portion into which a toner cartridge insertable from outside the main body through the communicating portion to be mountable, a toner inlet portion provided in the mounting portion to receive toner from the toner cartridge when the toner cartridge is mounted to the mounting portion, and an inlet shutter switchable between a blocking position where the toner inlet portion is blocked from receiving toner, and an inlet position where the toner inlet portion is open to receive toner. The printer includes a first latch member switchable between a first position where the inlet shutter is locked from switching between the blocking position and the inlet position and a second position where switching of the inlet shutter is allowed to switch between the blocking position and the inlet position, and a switching unit to switch between the first latch member between the first position and the second position.

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.
