Genuine OEM HP Color LaserJet CM4540fskm MFP Toners

For the Color LaserJet CM4540fskm MFP, high-yield HP 646X is the larger black-toner option, while HP 647A is standard-yield. Higher black capacity means more pages between cartridge changes. The cyan, magenta, and yellow supplies remain HP 646A with either black choice.

Toner Buzz carries genuine HP 647A and 646X black singles and 646A individual colors for the CM4540fskm MFP. Pick the black capacity for your printing volume and the individual colors your order needs. Fuser, transfer, and toner-collection parts are separate maintenance supplies; a full toner collection unit needs its own part, not another toner cartridge.
