Nacho's got it on the nose. Try the qtip method first to loosen the dried ink...then... Try going to your printer settings (from the control panel >> printers >> right click on your printer >> properties, and find 'maintenance' or 'cleaning' ...etc. it basically uses a mode that squirts ink out, then washes the head, then squirts some more. My HP printer offers light, intermediate, and heavy cleaning - try that. It 'does' use a fair amount of ink, but if the head is fubar, you might as well try.
