Genuine OEM HP Color LaserJet 5500hdn Toners

The HP 645A cartridges and the separate maintenance kits for the Color LaserJet 5500hdn have different roles. Toner cartridges supply the powder for printing; the transfer unit moves it onto paper and the C9735A fuser bonds it there with heat. Ordering toner does not service those maintenance parts.

Toner Buzz carries genuine HP 645A individual colors and the complete four-color set, plus separate fuser and image transfer kits for the 5500hdn. Choose the 645A set for black, cyan, magenta, and yellow together, or a single cartridge for one color. Match a maintenance request to the named kit.
