Genuine OEM HP Color LaserJet CM4730fm MFP Toners
The Color LaserJet CM4730fm MFP's HP 644A toner cartridges are separate from its maintenance kits. The fuser uses heat to fix toner onto the paper, while the transfer assembly moves toner to it. Ordering a toner set supplies the four colors, not either of those assemblies.
Toner Buzz carries genuine HP 644A individual cartridges and a four-color set for the CM4730fm MFP, plus separate fuser and transfer parts. Choose a single color for one cartridge need, or the 644A set for black, cyan, magenta, and yellow together. Fuser and transfer requirements remain separate from the toner order.
