I had to run 7 powerful cleaning cycles to get a 4900 printing again. The regular cleaning cycles did not produce any effect that I could tell. At one point, the printer was so clogged that it didn't print any nozzle check pattern with any of the inks. Then it gradually came back after the third power cleaning. That was 2 months ago and all seems fine now.
