Toner Cartridges, Maintenance Kits and Parts

One Item
The NP300 uses a single toner cartridge, CNM F412222210 (CNM F41-2222-210). CNM F412222210 yields 2850 pages.
The CNM F412222210 cartridge has an approximate yield of 2850 pages.
The "Supply Problem" notice on the NP300 is typically a recognition fault, not a defective cartridge. Start by turning the printer off for 30 seconds. Reseat the cartridge, clean its chip contacts with a dry cloth, then power back on. If nothing changes, the fix is a fresh CNM F412222210.
