Abstract
An inkjet printer that has a printhead IC with and array of ink ejection nozzles, an ink manifold for distributing ink to the printhead IC, the ink manifold having an ink inlet and an ink outlet, an accumulator, and a downstream pump in fluid communication with the ink outlet. The downstream pump is independently operable. This allows the printhead to be primed or deprimed for storage and transport and it allows the printhead IC to be cleaned by a foam formed by air forced through the ink election nozzles.
