  • Liquid ejection recording head
    Patent number: 7303260
    Abstract: A compact liquid ejection recording head capable of forming high-quality images at high speed includes large nozzles for ejecting large droplets, medium nozzles for ejecting medium droplets, and small nozzles for ejecting small droplets. The large nozzles are arranged on one side of an ink supply port, while the small nozzles and the medium nozzles are arranged on the other side of the ink supply port. The number of the small nozzles is larger than that of the medium nozzles, and that of the large nozzles. This allows high-quality and high-speed printing using the small nozzles, high-speed photo printing using the medium and small nozzles, and high-speed printing using the large nozzles.
