Abstract: A logic circuit, or method using the same, may include a memory storing (i) a plurality of partition groups, each partition group including a plurality of partitions, and (ii) a partition map defining an address and access mode for each of said partitions, defining different access modes for at least some of the partitions. The plurality of partition groups may comprise (i) a general use partition group including a first consumable level counter; (ii) a second use partition group including a second incrementally updatable consumable level counter; and (iii) a guide partition group including a use indicator to indicate which of the first and second consumable level counters to use.

Abstract: Examples of a container assembly are disclosed herein. An example of the container assembly includes a first body to supply printing composition and a second body to store reserve printing composition. The example of the container assembly additionally includes an interconnect having a storage position to fluidically isolate the first body from the second body and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body as needed to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body.

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: An example method comprising requesting authorization to reprocess a replaceable supply component using first data stored in memory of the replaceable supply component and an interface, the first data including original manufacturing data for the replaceable supply component. The method further comprises, in response to the request, receiving second data using the interface, and appending the original manufacturing data stored in the memory with the second data to designate the replaceable supply component as reprocessed.

Abstract: In one example in accordance with the present disclosure, at least one print liquid supply interconnected is described. Each print liquid supply interconnect includes a housing movable relative to a printer and tethered via a feed hose to the printer. The housing includes at least one needle to be inserted in a print liquid supply to allow print liquid to move between the print liquid supply and an ejection device and two keyed slots disposed on either side of a first needle to gate insertion to a print liquid supply with protrusions that match the two keyed slots. The housing also includes a guide feature adjacent the first needle extending between a first keyed slot and the first needle and an electrical interface to establish a data transmission path between the print liquid supply and the ejection device, the electrical interface disposed between the first needle and a second keyed slot.

Abstract: A fluid reservoir may include a fluid chamber to contain a fluid, and an impedance sensor exposed to a fluid within the fluid chamber. The impedance sensor senses an impedance at the impedance sensor, determines a particle vehicle separation level of the fluid within the fluid chamber based on the sensed impedance, and sends an activation signal to a moveable carriage to which the fluid reservoir is coupled to stir the fluid within the fluid reservoir based on the sensed impedance.

Abstract: In one example in accordance with the present disclosure a printer cartridge is described. The printer cartridge includes multiple backpressure chambers in fluid communication with a shared free fluid chamber. The backpressure chambers are to supply a fluid to nozzles of a portion of a fluidic ejection assembly and to provide backpressure to the nozzles of the fluidic ejection assembly during deposition of fluid onto a print medium.
