7 year Mutoh. Nozzel check, and black with multiple broken lines. It will not print well in wave, this after multiple head soakings, two little charges, cleaner down the capping section, lines clear, dampers look fine. Time to order my 2nd head in 8 years. I ordered it ( $2800) it's still in the box. I ran some prints in fine print mode, and it prints fine with more ink dropping. Is there something missing that I can do with my old head. Might it still be salvaged? I would rather keep it, and if I have to, hold on to the new head for future use if I can't return it......Any suggestions from the pros
