Experience (of others, not me) has shown that a high number of head  
cleaning cycles rarely solves such a problem. If it isn't gone after 2 or  
3 cycles the other 47 are unlikely to clear it. In such cases saturate the  
parking pad with steve's cleaning mix and drive the head onto it manually  
and let it sit. has cleaned every printer i tried it with right up.
