OKI C834 Black Drum Unit

New black toner in, but the pages still look grey or have that faint repeating mark across the sheet? The drum's telling you it's done. This is the black drum unit for your OKI C834 — it works alongside the toner to lay down a clean, solid image. You don't need both at once, but when the drum's worn, no amount of fresh toner fixes it. We've got 21 sitting on the shelf. Swap it in and the black channel pulls sharp again
