Toner Cartridges, Maintenance Kits and Parts

One Item
The NP3525 uses a single toner cartridge, CNM F414001100. CNM F414001100 yields 4000 pages.
The CNM F414001100 cartridge has an approximate yield of 4000 pages.
A "Supply Problem" message on the NP3525 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 F414001100 will clear it.
