Toner Cartridges, Maintenance Kits and Parts

One Item
The C235 uses a single toner cartridge, PIT 4170. PIT 4170 yields 24000 pages.
The PIT 4170 cartridge has an approximate yield of 24000 pages.
The "Supply Problem" notice on the C235 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 PIT 4170.
