Abstract: Certain examples relate to controlling recirculation processes in a printing apparatus. An example printing material cartridge includes a reservoir storing printing material to supply a printing apparatus; memory; and instructions for controlling a recirculation process in the printing apparatus, the instructions stored in the memory, the recirculation process to cause the printing material to move between the reservoir and a second printing material cartridge, the second printing material cartridge separately replaceable from the printing material cartridge in the printing apparatus.

Abstract: Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.

Abstract: Disclosed herein is a consumable item for a device, a printing device, and a method of operating a device. The consumable item for a device is to be removably inserted into the device and comprises a machine-readable storage medium that contains update information identifying a version of a software for the device.

Abstract: Certain examples described herein relate to replaceable production material containers for additive manufacturing systems. In an example of a replaceable production material container, an electrical storage device provides at least one production material characteristic to an element of an additive manufacturing system. In certain examples, the electrical storage device stores a range parameter for indicating a production material characteristic offset value in a plurality of production material characteristic offset values. In certain examples, the electrical storage device stores a proportion parameter for determining the at least one production material characteristic on the basis of the production material characteristic offset value.

Abstract: In an example, a data unit includes a data unit mounting having a circuitry region, a registration portion, and a retaining feature. Circuitry comprising a data source to provide at least one additive manufacturing parameter is arranged on the circuitry region of the mounting. The data unit mounting is to be removably mounted on a receiving portion of an additive manufacturing build material component, such that the registration portion is to be received in a corresponding guide portion of the receiving portion of the additive manufacturing build material component, and the retaining feature is prevent removal of the data unit from the receiving portion unless deformed. Deformation of the retaining feature to effect removal of the data unit from the receiving portion may be a permanent deformation.

Abstract: A dust collector (10) includes upper and lower apertured tube sheets (40, 42) within a collector housing, with a plurality of vertically extending filter tube assemblies secured to upper tube sheet apertures (44) and extending downwardly toward the lower tube sheet (42). Each filter tube assembly (54) has a filter tube (56) optionally equipped with a lower weight assembly (58) placing the tube (56) in tension. Particulate-laden gas passes through the upper ends of the filter tubes (56) and downwardly therethrough, causing particulates to collect on the inner surfaces of the tubes (56). Such collected particulates are periodically removed by generating vacuum shock pulses which act on the tubes (56) to dislodge the particulates.

Abstract: Examples associated with extensible markup language (XML) file condensing are described. On example includes generating a set of indexes from an XML file. The set of indexes may include a tag index that indexes tag terms used in the XML file, an attribute indexes attribute terms in the XML file, and a value index that indexes value terms in the XML file. The example also includes condensing the XML file into a condensed version of the XML file by translating the XML file according to the indexes. The example also includes generating a translated file. The translated file may be made from the set of indexes and the condensed version of the XML file.
