Query: Will dry out if not used! Expensive to repalce

I've installed my new cartridge about 6 months ago and have printed less than 20 pages. Now it appears to be dried out even though there is no indication that I've run out of ink. I've followed the instructions for cleaning the cartridge without any noticeable improvement. To get a new Sharp cartridge will cost me more than I've paid for the FAX machine itself.
