Genuine OEM HP Color LaserJet CM3530fs MFP Toners
The Color LaserJet CM3530fs MFP uses standard-yield HP 504A black toner. High-yield HP 504X black prints more pages between changes, but cyan, magenta, and yellow stay in the 504A family. A mixed 504X/504A set upgrades black, not every color.
Toner Buzz carries genuine HP 504A and 504X singles, four-color sets, and the 504X black two-pack for the CM3530fs MFP. Choose 504A black for lighter use or 504X for frequent printing. The black two-pack gives you a second cartridge; fuser, transfer, and toner-collection parts remain separate maintenance choices.
