Abstract
In a drop generator for use in an ink jet printer, stimulation transducers are bonded near the ends of the jet array on the droplet generator body. The transducers are electrically controlled with an oscillating voltage signal which can be modified in amplitude and phase with respect to the main driving signal. By altering the drive signal of the end transducers in amplitude and/or phase, the end sections being aligned with the solid end sections of the droplet generator, it is possible to match the vibration of the end sections with the central portion of the droplet generator. The result is more uniform stimulation down the length of the droplet generator.
