Abstract
Apparatus and method for providing a print fluid to a flow-through printhead. The printhead has a row of jetting channels configured to jet droplets of a print fluid, a supply manifold fluidly coupled to the row of jetting channels, and a return manifold fluidly coupled to the row of jetting channels. A first reservoir is fluidly coupled to the supply manifold, and a second reservoir is fluidly coupled to the return manifold. The first reservoir and the second reservoir are fluidly isolated except through the printhead.
