I've never had an inkjet printer before, so I don't > know about this sort of thing. Cartridges last a long time in the package. Make sure that the tape is still covering the ink jet surface when you open it. Also check that the top is not loose, which you may find with re-inked cartridges. If so, take it back and get a replacement.
