Abstract: An example print component includes a container interface with a guide feature to guide rotation and a rotationally asymmetric key feature. An example toner component includes a recess to receive a toner container, a guide feature to guide rotation of the toner container, and an asymmetric key feature embedded in the guide feature to guide a container material interface towards a component material interface upon rotation. An example container may have a periphery with a rotationally asymmetric surface plane to guide rotation of the container and a protrusion extending from the periphery that has a key feature defined by edges rotationally asymmetric with respect to the periphery. An example container may include a mechanical interface including an asymmetrically-located key feature that, upon rotation of the print material container, generates a sealing force substantially perpendicular to the direction of rotation.

Abstract: 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.

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: 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.

Abstract: An example device capable of predicting print substance end-of-life (EOL) comprises a container to hold a print substance, the container comprising a refill port through which print substance is to be introduced into the container. The example device also comprises a processor to receive signals indicative of an amount of print substance introduced via the refill port. The processor is also to predict a print substance end-of-life (EOL) based on the amount of print substance introduced.

Abstract: Example implementations relate to an apparatus to transfer a quantity of print material to a printing device through a transfer mechanism. In some examples, the apparatus includes a container including the quantity of print material, a transfer mechanism associated with the container, and a sensor associated with the transfer mechanism. In some examples, the sensor is to communicate to the printing device information about the transfer of the quantity of print material through the dispenser mechanism.
