ABSTRACT OF THE DISCLOSURE An improved method for operating an ink jet device comprises the steps of: First, operating the transducer 204 of the device for initiating the ejec- tion of an ink droplet from an orifice 202 via a first pressure disturbance within the ink chamber 200 asso- ciated with the orifice 202; and thereafter, prior to the ejection of an ink droplet from the orifice 202, operating the transducer 204 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 202 relative to the time of break-off without using the second pressure disturbance.
