Abstract:
A method of priming a printhead whilst minimizing nozzle drooling, the method comprising the steps of: (i) providing a printhead comprising: an ink distribution manifold having an ink inlet and an ink outlet; and one or more printhead integrated circuits mounted on the manifold, each printhead integrated circuit comprising a plurality of nozzles; (ii) providing an ink chamber in fluid communication with the ink inlet; and (iii) applying a positive pressure at the ink inlet whilst simultaneously applying a negative pressure at the ink outlet so as to draw ink through the manifold and prime the printhead whilst minimizing nozzle drooling.
