Hi A friend of mine with a 2100 little used had a similar problem which we thought were blocked nozzles. As a last resort we had an idea it was a cart ink supply problem not a blockage. I got him to use a bottom fill adapter on the offending cart to draw ink out. In fact the foam sponge was saturated in ink foam / air. Did this a couple of times refilled cart and problem was solved. Maybe this could be your problem. Hope this helps. Peter.
