An ink priming arrangement for an inkjet printhead is provided which has an ink bag containing ink for distribution to nozzles of the printhead via a fluid path between the ink bag and nozzles, a force applicator arranged to apply inwardly directed force on at least one exterior wall of the ink bag to reduce an available fluid volume of the ink bag, thereby causing ink to flow from the ink bag to the nozzles along the fluid path, and a biasing member arranged in the ink bag to apply outwardly directed force on at least one interior wall of the ink bag so as to restrain the reduction of available fluid volume of the ink bag. The biasing member applies the outward force only once the available fluid volume has been reduced to a predetermined volume. Each nozzle ejects an ink drop having a volume of about 1.2 picolitres.
