If there is any air bubble or dry ink on the print head, this will force it out, and allow it to print normally. Stand the cartridge upright for a few minutes before using. Then get a damp paper towel, fold it into quarters and sit the cartridge print head down onto it. Hold the cartridge against the damp paper towel for three minutes. This will help pull the ink out of the print heads, priming them and getting them ready to print. Clean the print head with rubbing alcohol.
