摘要： A liquid jetting apparatus jetting a liquid onto a recording medium conveyed in a first direction includes head units arranged in a second direction orthogonal to the first direction. One head unit includes nozzle chips; one nozzle chip has a nozzle arrangement area wherein nozzles are aligned in a third direction crossing the first and second directions. The nozzle chip is arranged to be shifted relative to another nozzle chip in a direction crossing the first and second directions and different from the third direction. The head unit has a first overlapping portion wherein nozzle arrangement areas of first and second nozzle chips included in the nozzle chips partially overlap with each other in the first direction. The liquid jetting apparatus has a second overlapping portion wherein nozzle arrangement areas of third and fourth nozzle chips included in the head units partially overlap with each other in the first direction.

摘要： A printing device comprises a droplet generator for generating a droplet of printing fluid, a droplet detector for detecting a generated droplet of printing fluid, and a controller. The droplet detector is moveable along an axis. The controller is to cause the droplet detector to be positioned at a known location along the axis, cause the droplet generator to generate a droplet, receive a measurement signal from the droplet detector, and determine a location of the droplet generator based on the received measurement signal and the known location.

摘要： Examples include a device comprising integrated circuit dies molded into a molded panel. The molded panel has three-dimensional features formed therein, where the three-dimensional features are associated with the integrated circuit dies. To form the three-dimensional features, a feature formation material is deposited, the molded panel is formed, and the feature formation material is removed.

摘要： A print head assembly including a print head unit, a cooling duct, and a blower arranged to pass a gaseous cooling medium through the cooling duct. The cooling duct has an elongated closed hollow cross-section bounded on at least one side by a flat wall. The print head unit is attached to the flat wall outside of the cooling duct such that the print head unit is cooled by the gaseous medium passing through the cooling duct via thermal contact through the flat wall of the cooling duct.

摘要： In one example, a shroud to protect a group of printheads in a printhead assembly includes a body having a first notched end where an upstream part of the body extends past a downstream part of the body and a second notched end opposite the first end where a downstream part of the body extends past an upstream part of the body. A first group of openings in the body is aligned across the upstream part of the body and a second group of openings in the body is aligned across the downstream part of the body. Each opening is to surround an exposed part of a printhead when the shroud is installed on the printhead assembly.

摘要： An inkjet head includes a head chip and an ink chamber. The head chip has a nozzle substrate provided with nozzles which discharge ink. The ink chamber is located over the head chip. In the ink chamber, the ink to be supplied to the nozzles is stored. The inkjet head is mounted on a mounting member. Between the nozzle substrate and the ink chamber, the inkjet head has a position reference substrate provided with butting parts. The butting parts are butted against the mounting member to position the inkjet head when the inkjet head is mounted on the mounting member.

摘要： A multi-channel fluid coupling for a printhead includes: a body having a first channel and a second channel, the second channel being relatively longer than the first channel; a first inlet port and a first outlet port at opposite ends of the first channel; and a second inlet port and a second outlet port at opposite ends of the second channel. The first and second channels are configured for proportionally modulating a flow resistance of fluids flowing therethrough.
