I just put about 1/2 inch of water in a small pyrex dessert-sized
dish, heat it in the microwave till it boils, wait about 10 seconds
and then place the cartridge right side up in the hot water for about
5 seconds so the print head gets wet, but not the main ink portion of
the cartridge. If that doesn't clear things, I repeat it. Never had
it fail, but I never wait until the cartridge is totally dry before I
clean and refill. Used this on Cannon, Epson, Lexmark, and HP
cartridges, refilled some 20+ times.

    ... There are two basic designs in inkjet heads, ... Thermal heads actually use heat the ink in each nozzle to around boiling so that stream develops in the ink and that steam pushes a drop of ink out of the end of the nozzle. ...

Thermal heads of either type (one time or permanent) cannot tolerate being activated for printing without ink in them for long or they will get overheated and melt or otherwise become damaged. ...
