Genuine OEM HP Color LaserJet 4600n Toners

The Color LaserJet 4600n uses HP 641A toner, but its C9725A fuser kit handles a different job. Toner cartridges supply the printing powder; the fuser uses heat to bond that powder to paper. New toner therefore does not address a fuser-maintenance warning.

Toner Buzz carries genuine HP 641A individual cartridges and a four-color toner set for the 4600n, plus the separate C9725A fuser kit. Pick a single 641A for one low color, or the toner set for black, cyan, magenta, and yellow together. The fuser kit is not included in that set.
