Toner Cartridges, Maintenance Kits and Parts

One Item
The 9925 uses a single toner cartridge, KNI 950133. KNI 950133 yields 3000 pages.
The KNI 950133 cartridge has an approximate yield of 3000 pages.
A "Supply Problem" message on the 9925 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 950133 will clear it.
