Black Genuine 2-Pack Toner Cartridge
The 9410 uses a single toner cartridge, OCE 25001878 (OCE B4).
The "Supply Problem" notice on the 9410 is typically a recognition fault on one of the colour cartridges, not a defect. Switch off for 30 seconds, reseat the reported cartridge, clean its contacts with a dry cloth, and power back on. If nothing changes, replace the cartridge for the colour the printer flags.
