  • Liquid ejecting apparatus
    Patent number: 8430464
    Abstract: A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle orifice, a blowing mechanism disposed on the liquid ejecting head side, and a gap control unit which relatively controls a gap between the nozzle orifices and an ejection target medium, in which driving of the blowing mechanism is controlled depending on the gap between the nozzle orifices and the ejection target medium.

  • Ink cartridge, ink-jet type printing apparatus using the same, and ink cartridge change control method in the apparatus
    Patent number: 7033009
    Abstract: An ink cartridge which has an IC memory for holding information about the cartridge. At the time the ink cartridge is to be installed in a printing apparatus, its insertion is inhibited at a position before installation by a lock mechanism. In this state, the information in the IC memory is read out via a first electrode terminal located on the cartridge side and connected to the IC memory and the propriety of the installation of the ink cartridge to the apparatus is determined. When the ink cartridge is determined to be appropriate, the lock mechanism is unlocked and the ink cartridge can be installed into the printing apparatus. When the ink cartridge is installed in the printing apparatus, data is exchanged between the printing apparatus and the IC memory via a second electrode terminal connected to the IC memory.
