Specifications

Genuine or compatible?

This item is a Royal compatible cartridge designed to replace the original Samsung SCX-D4521A black toner. It is not a genuine Samsung product. Royal compatible consumables allow businesses to run legacy office printers cost-effectively without sacrificing overall print clarity. Compatible cartridges fit directly into assigned slots, though minor density variations may occur compared to original toners, and OEM warranties are non-applicable.
