Abstract: A device to supply printing material to a printing material container of a printing apparatus includes a container including a plunger and to contain the printing material, a portal couplable to a refill port to the printing material container. The portal includes a discharge port through which the printing material is transferrable from the container, and a connector to receive power to move the plunger, to cause a transfer of the printing material contained in the container to the printing material container through the discharge port.

Abstract: In one example in accordance with the present disclosure, a refill container is described. The refill container includes a reservoir to house a volume of print compound and a chamber to house a pressurized fluid. A wall separates the reservoir from the chamber. A pressure release device of the refill container creates a fluid path between the chamber and the reservoir such that the pressurized fluid flows into the reservoir to mix with the volume of print compound. A trigger of the refill container activates the pressure release device.

Abstract: A dispensable substance container may include a printing substance dispensing nozzle including a first material. The dispensable substance container an elongate body, including a wall, including a second material encompassing a cavity to contain a dispensable substance, and an attachment portion to attach the elongate body to the printing substance dispensing nozzle; and a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body and the attachment portion are to be severed along the structurally compromised portion by a pushrod moveable through the cavity to expel the dispensable substance out the dispensing nozzle.

Abstract: A device is to supply printing material to a printing material container in a printing apparatus. The device includes a first container to contain printing material, a first piston movable in the first container to exert first pressure to discharge the printing material contained in the first container from the first container, a second container having an opening to the first container, and a second piston movable in the second container to exert second pressure higher than the first pressure to form a pressure gradient based on the first pressure and the second pressure through the opening. The pressure gradient is to disperse the printing material in the first container.

Abstract: An example print apparatus is described as including a fuser roller, a pressure device that generates wear on a section of the fuser roller surface, and a wear detection engine that identifies a degree of wear on the surface of the fuser roller. An example fuser roller may include a tube, a heating element, and a plurality of layers having a detectable pattern. An example print apparatus may include a wear detection engine having an emitter, a detector, and a controller that identifies a wear pattern based on data provided by the detector in response to activation of the emitter and determines a degree of wear based on the identified wear pattern.

Abstract: In various examples, colorant sensors can include a printing device comprising a hopper to receive a colorant, a supply to receive the colorant from the hopper, an aperture disposed between the hopper and the supply, a light emitter to emit light that passes through the aperture, and a light sensor located on the opposite side of the aperture relative the light emitter to sense a portion of the emitted light that passes through the aperture to permit determination of whether colorant present in the aperture based on the portion of the emitted light sensed by the light sensor.

Abstract: An example of a device (100) may include a valve body (108). The device may include a printing substance transfer window (122) through the valve body (108). The device (100) may include a printing substance dispensing nozzle (110) rotatable within the valve body (108) between a first orientation with an orifice of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second orientation with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer window (122). The device (100) may include a dispensing-side gasket material (132) slideable against the internal face of the valve body (108) when rotating the printing substance dispensing nozzle (110) between the first orientation and the second orientation.
