John,Paul and Frank have all been correct in their recommendations.
I've also learned that you can use a 50:50 mix of straight denatured alcohol(ie:ethyl) with distilled H2O in a syringe to gently clear the heads. The mixture will warm up as you make it and, if you allow it to set in the head for a few minutes, it will remove virtually any of the normal inks. If that doesn't do it you probably have a physical obstruction such as paper fibers blocking the nozzle.

Duane
