Abstract
A method and apparatus for supplying ink to an array of ink jets is provided by two fluidically independent reservoirs, each reservoir supplying ink to a respective end of a manifold which communicates with the array of ink jets via their inlet restrictors. During normal operations involving an acceleration of the array along a scanning path, the ink levels in the two reservoirs will remain the same since any difference in their levels will create a pressure differential that drives a flow of ink through the manifold from the higher level reservoir until such time that their levels equalize.
