Abstract: In some examples, an electronic device includes a network interface and a controller. The controller receives, via the network interface, an identifier of a radio frequency identification (RFID) tag, and generates a notification in response to the identifier being different from a set of identifiers stored to a storage device. The set of identifiers includes multiple identifiers associated with the RFID tag.

Abstract: A sensor circuit for a replaceable print apparatus component comprises an interface to transmit signals with respect to a print apparatus logic circuit, and further comprises, connected to the interface, at least two sensor cell arrays, each array including nominally the same cells, the cells of one array being nominally different than the cells of the other array, and at least one single cell sensor that is nominally different than the other cells.

Abstract: In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component, responding to a first validation request sent via an I2C bus to a first address associated with the logic circuitry with a first validation response; and responding to a second validation request sent via the I2C bus to a second address associated with the logic circuitry with a second validation response.

Abstract: In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, receiving a sensor data request and determining whether the request is for data indicative of a print material level or for data indicative of a pressurisation event. In the event that the request is a request for data indicative of the print material level, the method may comprise responding with a first data response in a first value range; and in the event that the request is a request for data indicative of a pressurisation event, the method may comprise responding with a second data response in a second value range.

Abstract: A logic circuit for a replaceable print component is configured to, in response to a plurality of commands including a first command specifying the new I2C communications address and a first calibration parameter, a second command specifying the new I2C communications address and a second calibration parameter, a third command specifying the new I2C communications address and a class parameter, and/or fourth commands specifying the new I2C communications address and sub-class parameters, and at least one read request, generate count values in a count value range defined by a highest and lowest count value.

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: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and a logic circuit having a communication address to communicate with the print apparatus logic circuit. The logic circuit is configured to detect, via the interface, communications that include an other communication address. The logic circuit is configured to respond, via the interface, to a command series directed to the logic circuit that include the communication address of the logic circuit, based on the detected communications.
