摘要： An apparatus includes nozzles and an ink passage. Each nozzle includes a pressure chamber which houses an electrothermal transducer provided on a substrate to apply ejection energy to ink, an ink ejection orifice which faces the electrothermal transducer, and an ink passage along which the ink is supplied to the pressure chamber. The ink supply port is provided on the substrate and communicates with the ink passages. A distance between a center of gravity of the electrothermal transducer and the ink supply port differs between the nozzles which are next to each other. In at least one of the nozzles, a center of gravity of the ink ejection orifice is shifted from that of the electrothermal transducer in a direction toward the ink supply port by an amount which is increased as the distance increases.

摘要： In an ink jet printing apparatus, preliminary ejection for a print head involving a plurality of distances from a common ink supply port to respective ejection openings is optimized. Specifically, for a first nozzle array and a second nozzle array with different distances from the ink supply port to the ejection opening, the ratio of a driving pulse width to a lower limit pulse width for the second nozzle array with the longer distance is set to be higher than the ratio for the first nozzle array with the shorter distance. This enables a reduction in the time required for preliminary ejection of the apparatus as a whole.
