Method of priming a printhead with ink bubbles present in a printhead assembly |
摘要 |
A method of priming one or more printhead integrated circuits, the method comprising the steps of: (i) providing a printhead assembly comprising: an ink distribution manifold having an ink inlet and an ink outlet; one or more printhead integrated circuits mounted on the manifold, each printhead integrated circuit comprising a plurality of nozzles; an upstream ink line connected to the ink inlet; and a downstream ink line connected to the ink outlet, wherein at least part of the printhead assembly contains ink bubbles; (ii) providing an ink chamber in fluid communication with the ink inlet via the upstream ink line; (iii) priming the printhead integrated circuits by drawing ink from the ink chamber, through the manifold and into the downstream ink line using a pump; (iv) bursting ink bubbles in the downstream ink line; (v) sensing for ink downstream of a bubble-bursting point in the downstream ink line; and (v) shutting off the pump when the ink is sensed.
