Brothers TN-2331 OPC Drum for 2331 2245 2250 7055 7057 7060D 7360

The Brother TN-2331/DR-2255 OPC Drum is a precision-engineered optical cylinder designed for Brother’s mid-range monochrome laser printers and multi-function machines. Constructed on a durable, lightweight aluminum foundation and finished with a high-sensitivity photo-conductive coating, it relies on static electricity to accurately capture and transfer toner onto the page. This drum ensures sharp text and smooth grayscale gradients, delivering a reliable duty cycle of up to 12,000 crisp pages at standard 5% coverage. It serves as an essential maintenance replacement for popular office models like the HL-2240, DCP-7060D, and MFC-7360 series, successfully resolving common wear-and-tear print defects such as faded text, ghosting, background shading, and repetitive vertical lines.
