Genuine OEM HP Color LaserJet CM4540 f Toners

The Color LaserJet CM4540 f uses a mixed toner set with HP 646X black and HP 646A cyan, magenta, and yellow. The HP 648A item serves as a toner collection unit, so it answers a different message than the four toner cartridges.

Toner Buzz carries the genuine HP toner set and HP 648A collection unit for this model. Choose the set for the four print colors and the collection unit only when the printer asks for that maintenance item.
