Abstract: An example method comprising requesting authorization to reprocess a replaceable supply component using an interface and original manufacturing data stored in memory of the replaceable supply component. The method further comprises, in response to the request, receiving configuration data using the interface, and appending the original manufacturing data with the configuration data to designate the replaceable supply component as reprocessed, wherein the configuration data is to cause reconfiguration of an end-user device in response to attachment of the replaceable supply component to the end-user device and execution by the end-user device.

Abstract: Generating a request for reprocessing of a replaceable supply component may include sending to a non-volatile memory of a replaceable supply component, a request for information about the replaceable supply component. The method may include receiving from the replaceable supply component, the supply component information, wherein the supply component information includes data to be decrypted by an exchange service. The method may further include generating a request blob including the supply component information, and cryptographically signing the request blob for sending to the exchange service for reprocessing of the replaceable supply component.

Abstract: Reprocessing of a replaceable supply component may include receiving from an encoding device and using an interface communicatively coupled to the encoding device, a request blob to reprocess a replaceable supply component. The method may include in response to cryptographically verifying the request blob, extracting from the request blob, a supply identifier and raw supply data. The method further includes using the supply identifier and raw supply data, generating a reprocess structure to append or amend original manufacturing data for the replaceable supply component, and providing a response blob to the encoding device, to designate the replaceable supply component as a reprocessed supply component.

Abstract: A print material refill container includes a housing and a chamber, within the housing, to contain a print material. The print material refill container includes a physical indicator subject to modification based on an engagement of the physical indicator with an engagement member of a printing device when the print material refill container engages the printing device to deliver the print material to a reservoir of the printing device. The physical indicator indicates an unused condition of the print material refill container when the physical indicator has a first state prior to the modification, and the physical indicator indicates a used condition of the print material refill container when the physical indicator has a second state subsequent to the modification.

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.
