ABSTRACT:
A method and apparatus to prevent ink starvation includes keeping ink in a primary common reservoir at a high pressure. The ink is transferred from the primary common reservoir to a local reservoir when a pressure drop across a restrictor decreases pressure in the local reservoir. The pressure drop across a restrictor results from a higher ink flow rate due to rapid firing of the transducer.
