Genuine OEM HP LaserJet Enterprise M604n Toners

HP 81A toner and the maintenance kit for the LaserJet Enterprise M604n are separate purchases. The cartridge supplies toner, while the kit contains paper-feed rollers and the fuser, the part that bonds toner to paper.

Toner Buzz offers genuine HP 81A black cartridges and the F2G76A and F2G77A kits for this model. When ordering a kit, choose the 110-volt or 220-volt version that matches the printer's electrical rating.
