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 printing device determines that a consumable item newly installed within a printing device has previously been used, based on a remaining life of the consumable item. In response to determining that the consumable item has previously been used, the printing device resets the remaining life of the consumable item.

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.

Abstract: Examples of a print particle transfer interface of a donor container are described herein. Some examples of the print particle transfer interface include a static interface portion to engage a receiving container. The static interface portion includes a static opening. Some examples of the print particle transfer interface include a rotating output assembly with a cylindrical valve seat and a seal component surrounding a valve opening. In some examples, the cylindrical valve seat rotates with respect to the static interface portion to align the valve opening for dispensing print particle to the receiving container.

Abstract: An example method comprises setting a mixture of a plurality of print supplies of a print device to use for a process black print based on a plurality of supply levels corresponding to the plurality of print supplies. The example method further comprises initiating execution of the process black print of a print job by the print device using the set mixture of the plurality of print supply as overlapping colorant with the black print supply of the print device.

Abstract: In an example, a print component includes a guide structure. The example guide structure includes a recess to receive a print material container and a guideway with a guide wall to support rotation of the print material container. Upon rotation of the print material container, an electrical contact of the print material container moves towards an electrical contact coupled to the guide structure of the print component. In another example, a container includes a housing, a material transfer interface, and a mechanical interface. In that example, the mechanical interface includes a guide structure that defines a protrusion and a guideway to allow the container to rotate within a recess defined by a receptacle shell. Upon rotation of the container, an electrical contact coupled to the guide structure moves towards an electrical contact on the receptacle shell.

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: The location of a printing device is determined. Environmental conditions in which the printing device operated when printing a print job are determined based on the determined location. An environmental adjustment factor for the printing device is determined based on the determined environmental conditions. A predicted print material usage of the printing device in printing the print job is adjusted based on the determined environmental adjustment factor.
