Black Genuine 2-Pack Toner Cartridge 2 x 2,600 pages
The HL 2380DW uses a single toner cartridge, BRT TN6602PK (BRT TN-660 2PK).
The "Supply Problem" notice on the HL 2380DW 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.
These quick tips apply to all laser printers. While your exact model may look slightly different, the steps are identical.
