Original OEM Drum Unit HP 57A (CF257A) (Black) is the key component that helps your HP LaserJet keep its professional, razor-sharp look page after page. Dear Customer, if you rely on consistent black text, crisp lines and clean graphics, a fresh drum unit is what restores that “like new” precision to your laser prints.

As an Original OEM HP drum, this model is designed for perfect fit, stable operation and predictable performance in everyday office printing.
With a yield of up to 80,000 pages (at 5% coverage), the HP 57A drum unit is made for high-volume environments where downtime is not an option. We also make sure every parcel is carefully protected before transport, so it arrives ready for installation.
