Faint cyan lines, fading colour, or a drum-alert light you've been ignoring for a week? The drum unit is the component doing that work, and it's worn out. This is the OKI cyan drum unit made for the C911. Swap it in, and your cyan channel prints like it did on day one. No software updates, no recalibration dance. Just a clean, solid part
