Claim:
An imaging device comprising: a plurality of ink jets for emitting ink toward an image receiving surface; a first reservoir configured to contain ink, the first reservoir being associated with a printhead and being in fluid communication with a plurality of ink jets in the printhead for delivery of ink from the first reservoir to the plurality of ink jets; a second reservoir spaced apart from the first reservoir, the second reservoir being configured to contain ink for delivery to the first reservoir; an ink delivery and recovery system including: a first conduit connected between the first reservoir and a junction, the first conduit including a flow path restriction that permits flow of ink in only a single direction from the junction toward the first reservoir; a second conduit connected between the junction and the second reservoir; and a bidirectional pump associated with the second conduit and configured to pump ink in a first direction to cause ink to flow from the second reservoir toward the junction.
