Breakdown:

DRUM: Refers to a drum unit, a critical component in laser printers and copiers that transfers toner to the paper. It works with the toner cartridge but is usually a separate part.

OEM: Stands for Original Equipment Manufacturer, meaning it's a genuine, brand-original part — not third-party or remanufactured.
