Abstract
A inkjet printer that has an ink supply (), a printhead integrated circuit (IC) () in fluid communication with the ink supply via an upstream ink line (), the printhead IC (), a waste ink outlet in fluid communication with the printhead IC () via a downstream ink line (), an upstream shut off valve () in the upstream ink line (), and, a downstream pump mechanism () in the downstream ink line. With a valve upstream of the printhead and a pump downstream of the printhead, the user has active control of the ink flow upstream, downstream or in the printhead IC. In the event that problems such as ink flooding, color mixing or printhead depriming occur, the user can follow simple troubleshooting protocols to rectify the situation.
