A print material container comprising a body to hold print material, a housing, and a detecting member. The housing being coupled to the body and including a movable mass to move in the housing when a shaking force is applied to the print material container. The detecting member to detect the shaking force and to signal a feedback of the shaking force relative to a shaking force threshold.

Print material container

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

Rotatable dispensing nozzles

A dispensable substance container may include an elongate body encompassing a lumen, wherein the lumen is to contain the dispensable substance; a dispensable; substance dispensing nozzle attached to a first end on the elongate body; a sealing material within the lumen, wherein the sealing material is moveable, by a pushrod, within the lumen to push the dispensable substance out the dispensing tip; and a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body is to be severed along the structurally compromised portion by the pushrod.

Dispensable substance containers

An example print material replenishment device includes a container to contain print material, a dispensing end to engage a fill port of a printing device, the dispensing end including an opening that is offset from a center axis of the container, and a rotatable cover coupled to the dispensing end, the rotatable cover to expose the opening of the dispensing end based on a rotation of the print material replenishment device.

Print material refill device

A device may include a dispensable substance container to hold a dispensable substance; a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle; and a frangible obstruction encompassing the dispensing nozzle and obstructing the opening of the dispensing nozzle wherein the frangible obstruction is to slide along the dispensing nozzle to uncover the opening when broken free from the dispensing nozzle by a wall of a receiving container during an engagement between the dispensable substance container and the receiving container.

Dispensing nozzles

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.

Severable dispensable substance containers

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.

Device to supply printing material

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.

An example device can include a reserve print materials container, an access port coupled to the reserve print materials container to receive, from a replenishment device, print materials directly to the reserve print materials container in-situ, and a main print materials container coupled to the reserve print materials container to receive print materials from the reserve print materials container.

Combination cartridge

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.

Refill containers with pressurized fluid chambers

Examples described herein relate to an apparatus for particulate delivery consistent with the disclosure. For instance, the apparatus may comprise a particulate reservoir container, an orifice positioned at an output portion of the particulate reservoir container, and a baffle that when compressed forces air through an air valve to direct the air below a level of particulates of print material to aerate the particulates of print material.

Particulate delivery container

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.

Print materials replenishment

A print material container comprising a body, a transfer mechanism, an inner connector, and an outer connecter. The transfer mechanism is to move print material in or out of the body. The inner connecter is on a connecting side of the body, and is to couple to a first location of an image forming apparatus to provide print material to the image forming apparatus. The outer connecter is on the connecting side of the body, and is to couple to a second location of the image forming apparatus to collect or receive unutilized print material transferred or received from the image forming apparatus.

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.

Fuser rollers

Examples described herein relate to a print substance container consistent with the disclosure. For instance, the print substance container may comprise a print substance disposed inside of the print substance container and a first electromagnet formed of a wire coil positioned around the print substance container and extending along a length of the print substance container.
