Abstract
An ink transport system for an acoustic ink printer having an array of ejectors with associated ink bodies and free surfaces. The ink transport system supplies ink to the injector ink bodies constantly, yet zeros the hydrostatic gauge pressures of the free surfaces of the ink bodies to ensure uniformity of ejector performance. The ink transport system works with linear and two-dimensional arrays of ejectors.
