Genuine OEM HP Color LaserJet CM3530 MFP Toners
For the Color LaserJet CM3530 MFP, HP 504A black is standard-yield. HP 504X black is high-yield, giving you more pages between black cartridge changes. The color cartridges remain 504A, so choosing the mixed 504X/504A set doesn't change the cyan, magenta, or yellow supplies.
Toner Buzz carries genuine HP 504A black, 504X black, and 504A colors for the CM3530 MFP. Choose singles, a four-color set with either black capacity, or the 504X black two-pack for an extra cartridge on hand. Separate fuser, transfer, and toner-collection parts cover maintenance, not new printing toner.
