I had exactly the same issue... Like Wayne, a service call fixed the issue, and in fact the printer seems to be running better than ever. Several parts were replaced, but the most interenting item, is that when the serviceman "unplugged" the ink line at the head, it appeared that there may have been a small leak, as there was a small amount of cyan ink around the gasket. The serviceman mentioned that on several printers he had worked on, the connection did not appear to be very tight. Whether it was the parts that fixed the issue or the tightened connection I wouldn't dare say. But things seem to be better.
