Toner Cartridges, Maintenance Kits and Parts

One Item
The 7222 uses a single toner cartridge, KNI 950246 (KNI TN301K). KNI 950246 yields 30000 pages.
The KNI 950246 cartridge has an approximate yield of 30000 pages.
If your 7222 displays a "Supply Problem" alert, it's almost always the cartridge chip not being read correctly — not a faulty cartridge. Switch the printer off for about 30 seconds, take the cartridge out and slot it back in firmly, then wipe the small metal chip contacts with a dry, lint-free cloth. Still showing the alert? Install a fresh KNI 950246 or reach out to our support team.
