Clog detection and clearing method for ink delivery system

The present invention disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station mounted to a scanning carriage. The receiving station has a fluid inlet and a pair of guide rails extending along either side of the fluid inlet. The replaceable ink container includes a fluid outlet configured for connection to the fluid inlet associated with the receiving station. Also included is a pair of outwardly extending guide rail engagement features. Each of the pair of guide rail engagement features are so disposed and arranged on the replaceable ink container for engagement with each of the pair of guide rails to guide the replaceable ink container in both horizontal and vertical directions into the receiving station. The pair of outwardly extending guide rail engagement features and the pair of guide rails cooperate to align the fluid outlet with the fluid inlet to establish fluid communication between the ink container and the receiving station.
