Magenta's fading, you're seeing thin streaks, or the colour just isn't hitting like it used to? Chances are your magenta drum unit is wearing out — and swapping toner alone won't fix it. This is the genuine OKI magenta drum for the C831N. It handles the electrostatic imaging that pulls toner onto the page. Replace it, and your magenta comes back solid
