Genuine OEM Xerox WorkCentre 4150 XF Toners

For the WorkCentre 4150 XF, the SMart Kit name refers to the 013R00623 drum, not printing toner. It is a separate maintenance supply from the black toner cartridge, so the two products address different needs rather than offering two versions of the same cartridge.

Toner Buzz carries genuine Xerox 006R01275 black toner and the 013R00623 drum for this printer. Choose the toner cartridge for a fresh-toner order or the drum for a drum-maintenance order. You do not need to treat them as a pair simply because both relate to black printing.
