I'll say this, I take my empty cartridges to a shop that re-fills black for $10 & color for $12 (yes from my hp 4630 all-in-one!) Have never had a problem, once in a while it will pop up with a "counterfeit" warning and ask if I want to proceed, I click the "yes" , problem solved! I have done this with every printer I've own, Maybe I just got lucky to find someone that knew what they were doing
