摘要： Provided is a pagewidth printhead with a controller, the printhead having a plurality of micro-electromechanical nozzle arrangements. Each nozzle arrangement includes a multilayered substrate defining an ink inlet passage and walls extending from the substrate. Also included is a nozzle plate supported by the walls to define a nozzle chamber in fluid communication with the ink inlet passage, the nozzle plate having a nozzle rim defining an ejection port in fluid communication with the nozzle chamber. Each arrangement also includes a plurality of heater elements suspended between the walls in the chamber, so that when electrical actuation energy is applied to respective heater elements a vapour bubble is formed in the fluid leading to a pressure increase in the chamber thereby ejecting the fluid via the ejection port. The controller is configured to individually actuate respective heater elements to facilitate weighted ink drop volumes to be ejected from the nozzle arrangement.

摘要： A thermal inkjet printhead with bubble forming heater elements formed from a material with a nanocrystalline composite structure.Nanocrystalline composite films can be superhard and can facilitate removal of the SiC and Ta anti-cavitation wear coatings. Improved oxidation resistance can also be achieved with some nanocrystalline composites, facilitating removal of the Si3N4 oxidation prevention coating. By removing or reducing the protective coatings, the heater element requires much less energy to form a bubble in the ink. A further benefit is improved crack resistance, which can extend the lifetime of uncoated heaters.
