Abstract
An ink jet print head is provided having an ink chamber and a nozzle plate closing the ink chamber at an end comprising a nozzle for ejecting a drop of ink through it. The nozzle plate further includes an ink path for flowing an ink through in a direction parallel with the nozzle plate and passing the inner end of the nozzle. This ink flow is in excess of that required for replenishing the ejected drops of ink in the ink chamber and may flow continuously passed the inner end of the nozzle and along the ink path to refresh the ink that is used for ejecting through the nozzle.
