Toner Cartridges, Maintenance Kits and Parts

One Item
The NP500 uses a single toner cartridge, CNM F412222210 (CNM F41-2222-210). CNM F412222210 yields 2850 pages.
The CNM F412222210 cartridge has an approximate yield of 2850 pages.
A "Supply Problem" message on the NP500 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 CNM F412222210 will clear it.
