FS- 4200DN
Stepping up to departmental volume, the FS-4200DN brings faster throughput and a sturdier duty cycle to workgroups with serious daily print loads, with duplex and network connectivity standard. Its black toner is the TK-3122 (TK3122), Kyocera's North American part number for this printer's cartridge, rated at roughly 15,500 pages. Fleets that mix this printer with its smaller siblings benefit from the shared cartridge family: one supply type, one ordering routine.
A departmental printer lives or dies by how invisible its upkeep is, and the FS-4200DN is built for that test. It sits on the network as a floor's shared engine, turning out two-sided work all day, while the supply side stays at a single high-capacity cartridge changed at long intervals. The same TK-3122 also feeds the M3550idn multifunction, so mixed hardware does not mean mixed toner stock.

The two single-cartridge listings are the same TK-3122 under duplicate store listings; either one is the correct cartridge.
Which cartridge should you buy?
Capacity is generous to begin with — around 15,500 pages per cartridge — so most departments should think in terms of spares rather than yield tiers. A single cartridge plus the discipline to reorder at the low-toner warning works for moderate floors. The 2 pack removes the risk entirely: the spare is already in the building when the warning appears. Floors running the FS-4200DN alongside the M3550idn, or printing at genuine departmental volume, should standardize on the 4 pack and let one carton size cover the fleet, lowering both the per-page cost and the ordering overhead.
Chip, toner and everyday use
Each compatible TK-3122 is chipped for this printer family, keeping the toner gauge honest from the first page to the last. Swap cartridges with the machine on and it will recognize the new unit automatically. Toner that has been sitting in a half-used cartridge can settle; a gentle end-to-end rock before reinstalling evens it out and clears up faint patches. Keep unopened spares in their sealed packaging, stored flat at room temperature, and avoid leaving a cartridge in direct sunlight even briefly — the photosensitive surface inside prefers the dark.
