I own Lexmark X9350 All-in-One printer. I switched it off for almost a year. Recently, I switched it on, but found that mu two cartridges are almost empty. So I sent them for re-fill. The black cartridge was ok re-filled. But the color one could not be refilled. I was told that it dried out. The shp owner doesn't know how to un-dry it. Any help how to solve this problem? Tnanks!
