ABSTRACT:
An improved method for operating an ink jet device comprises the steps of: First, operating the transducer of the device for initiating the ejection of an ink droplet from an orifice via a first pressure disturbance within the ink chamber associated with the orifice; and thereafter, prior to the ejection of an ink droplet from the orifice, operating the transducer for producing a second pressure disturbance, lower in amplitude than the first pressure disturbance, for increasing stability by causing earlier break-off of the droplet at the orifice relative to the time of break-off without using the second pressure disturbance.
