Toner Cartridges, Maintenance Kits and Parts

One Item
The 7030 uses a single toner cartridge, KNI 950236. KNI 950236 yields 26000 pages.
The KNI 950236 cartridge has an approximate yield of 26000 pages.
The "Supply Problem" notice on the 7030 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 KNI 950236.
