Toner Cartridges, Maintenance Kits and Parts

One Item
The 2423 uses a single toner cartridge, GST 2960916. GST 2960916 yields 7000 pages.
The GST 2960916 cartridge has an approximate yield of 7000 pages.
The "Supply Problem" notice on the 2423 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 GST 2960916.
