I got a Lexmark cartridge thats fits an old Lexmark 1020. Its one where you can only have color or black at a time. I put the black in a ziplock bag while the color was in there and apparently it has dried out. Is there anyway to save it by filling it or somehow getting the end opened if it dried in the jet end? Any little tricks I might can pull? If not whats the cheapest place to buy a cartridge? thanks
