Genuine OEM HP Color LaserJet 4730xs MFP Toners

The Color LaserJet 4730xs MFP uses HP 644A cartridges for toner, with separate kits for the fuser and transfer assembly. Those assemblies handle toner after it leaves the cartridge: the transfer unit moves it to paper, and the fuser bonds it with heat. They are not part of a toner set.

Toner Buzz carries genuine HP 644A single colors and the black, cyan, magenta, and yellow toner set for the 4730xs MFP. Order one cartridge for one low color, or the set for all four together. Fuser and transfer parts are separate choices for the printer's maintenance needs.
