A method of preparing a printer cartridge for transport may comprise applying a volume of immiscible fluid to a nozzle bore of a printhead. A printer cartridge may comprise a volume of immiscible fluid deposited into a nozzle bore of a nozzle of the printhead and a layer of immiscible fluid applied over the nozzle bore opening. A printhead die may comprise a volume of immiscible fluid deposited into a nozzle bore of the die and a layer of immiscible fluid applied over the nozzle bore opening.

A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

A method of welding a first member and a second member together includes preparing the first member and the second member, bringing the first member and the second member into contact to form a space between the first member and the second member, and bringing a welding horn into contact with the first member or the second member. The method of welding further includes performing a vibration process to vibrate the welding horn to weld the first member and the second member together by frictional heat, and performing a fluid-flow process to make fluid flow through the space. The fluid-flow process is performed during the vibration process.

A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

A remanufactured ink cartridge and a method thereof are provided in the present disclosure. The remanufactured ink cartridge is suitable for an inkjet printer with an ink-suctioning needle and a limiting protrusion which are configured to be adjacent with each other; an original ink cartridge includes a case and an ink discharge part; a cavity for storing the ink is formed in the case; the cavity is separated by a separation plate into a first cavity and a second cavity which are connected to each other through a channel. The remanufacturing method includes forming a limiting groove facing the cavity on the case and adjacent to the ink discharge part, wherein the limiting groove is connected to the second cavity, configured to allow the limiting protrusion to enter the second cavity; and blocking the channel to cut off a fluid connection between the first cavity and the second cavity.

The present application discloses an inner container type ink cartridge and a manufacturing method thereof. The manufacturing method includes the following steps: removing an upper cover of an original ink cartridge to obtain a cartridge shell; electrically connecting an external control circuit board with an original control circuit board of the original ink cartridge; arranging an internal control circuit board at a corresponding position of an inner container; and installing the inner container in the cartridge shell, so that internal contacts of the internal control circuit board of the inner container are electrically connected with the external control circuit board. A first chip of the external control circuit board or a second chip of the internal control circuit board is written with actual ink volume data of the inner container and an adopted program.
