ABSTRACT:
A method of priming a printhead. The method includes the steps of: (i) providing a printhead having a plurality of nozzles for ejection of ink, an ink inlet and an ink outlet; (ii) providing an ink chamber having an outlet port connected to the ink inlet via an upstream ink line, the ink chamber having an inlet port controlled by a valve; (iii) priming the printhead by pumping ink from the ink chamber, through the printhead and into a downstream ink line connected to the ink outlet; and (iv) opening the valve if a level of ink in the chamber falls below a predetermined first level and replenishing with ink from an ink reservoir when the valve is open.
