Brother DR-240BK Black Imaging Drum 15000 Pages

Brother DR-240BK Black Drum

The Brother DR-240BK drum unit forms the black imaging layer that transfers toner onto paper in compatible Brother color laser systems. This genuine drum assembly includes a photosensitive cylinder, cleaning blade, and waste toner channel engineered for extended duty cycles. Brother rates the unit near 15000 pages, making it a long-interval consumable compared with standard black toner cartridges on the same platform. The organic photoconductor surface accepts laser exposure with stable sensitivity across the rated life span. A primary charge roller maintains uniform electrostatic potential before each print cycle begins. Waste toner routes into an internal hopper that prevents spillage inside the printer frame. Service teams replace this module when text shows ghosting, vertical streaks, or background shading that toner swaps cannot fix.
