Your yellow channel's gone patchy or faded and swapping the toner hasn't fixed it? That's the drum. This is the genuine OKI yellow drum unit for the C650DN. It's a dedicated drum component, separate from the toner cartridge you already have. Fit it in and your yellow output comes back even. No guesswork — it's made for that one printer
