Toner Cartridges, Maintenance Kits and Parts

One Item
The 7115 uses a single toner cartridge, KNI 950280 (KNI TN101K). KNI 950280 yields 11000 pages.
The KNI 950280 cartridge has an approximate yield of 11000 pages.
A "Supply Problem" message on the 7115 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement KNI 950280 will clear it.
