  • Patent number: 7347529
    Abstract: A compound inkjet print head printer has a compound print head module. The compound print head module includes at least two inkjet print heads for providing ink droplets of one color but with different sizes. Since the compound inkjet print head module provides different sizes of ink droplets in a swath, the number of print swaths can be decreased. The compound inkjet print head printer increases a printing speed with high photo quality.

  • Patent number: 7296875
    Abstract: A cleaning device is mounted on either of the sides of an ink-jet printer. The cleaning device uses the power source of a paper delivering motor to transmit power to the cleaning units so that the cleaning units rotate to perform cleaning and scrubbing operations for an ink-jet print head. When the printer performs printing operations, the paper delivering motor is used to deliver paper without causing an interference with the ink-jet print head during the printing operation. When the ink-jet print head needs to be cleaned, an ink carriage moves to be opposed to the cleaning device under the ink carriage, then, the paper delivering motor supplies power to drive an external transmission device set. The external transmission device set drives the cleaning device on the revolving seat to rotate so as to clean the ink-jet print head of the ink carriage.

  • Publication number: 20050074546
    Abstract: A thin film-forming method and apparatus for forming flat films on a substrate utilizes micro-dispensing inkjet printing. Physical vibration is induced on the substrate to destroy the surface tension of droplets adhering on the substrate. The physical force influence the surface tension and holds the solute in position and prevent them moving by capillary force to the rim of droplet and accumulating there so as to get a flat thin film during the volatilization of the droplet. The vibration also regulates the droplet shape into nearly true round.
