Abstract

An ink circulation system for use in an inkjet printing apparatus includes an inkjet printhead, an ink supply path for supplying an ink to the inkjet printhead and an ink return path for returning ink not used for printing from the inkjet printhead. The ink return path is coupled to the ink supply path for replenishing the ink supply path with the ink returned from the printhead. The coupling establishes an ink circulation circuit. The ink circulation circuit can be replenished with fresh ink from a main tank, as ink is withdrawn by the printhead for printing. In the circulation system an active through-flow ink degassing unit is provided to control the dissolved gas level of the ink in the ink circulation system.
