    Abstract: A liquid ejection head includes a plurality of recording element substrates that each include an energy generating element generating energy utilized for ejecting a liquid and that each have a supply port through which the liquid is supplied to the energy generating element, a plurality of support members that each have a flow passage communicating with a corresponding one of the supply ports and that each support a corresponding one of the plurality of recording element substrates, a base substrate that supports the plurality of support members, and a heat insulating member disposed between the flow passages and the base substrate. In the liquid ejection head, a thermal conductivity of the support members is equal to or greater than a thermal conductivity of the recording element substrates, and a thermal conductivity of the heat insulating member is less than a thermal conductivity of the base substrate.

    Abstract: An inkjet printer including a printhead with a fluid ejection chip and an associated method of forming is described. The fluid ejection chip includes a substrate, a plurality of groups of drive elements formed on the substrate, and a plurality of fluid ejection devices disposed on the substrate. Each group of drive elements includes at least two drive elements electrically coupled in parallel. Each fluid ejection device of the plurality of fluid ejection devices is electrically coupled with a respective group of the plurality of groups of drive elements so that the plurality of drive elements selectively activate the plurality of fluid ejection devices for causing fluid to be expelled from the printhead in accordance with image data.
