Abstract
An inkjet printing apparatus is provided with a one-way valve to enable a single conduit to supply ink to an ink reservoir and withdraw purged ink from a receptacle into the ink reservoir. A bi-directional pump is operated in both directions in an alternating manner to withdraw ink from the receptacle when supplying the ink reservoir with ink.
