FAQ

How do I know which cartridge my HP LaserJet Pro MFP M521dn takes?

Check the label inside the toner door or the model number on the old cartridge; the cartridges listed above are the ones HP specifies for this printer.

Can I use a compatible or refilled cartridge?

You can, but page yield, print quality and level reporting vary and some printers flag non-genuine chips. We only sell original HP cartridges.
