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.
