FS-4000DN

The FS-4000DN is the flagship of this Kyocera monochrome family: duplex and network connectivity are fitted as standard, and the engine is built to absorb the heaviest print queues in the building. What makes it easy to run is the choice of three toner tiers. The top tier is the TK-332 — the same cartridge written TK332 across the Clever Supplies listings — rated for roughly 20,000 pages and carrying Kyocera's factory number 1T02GA0US0. Below it, the TK322 covers about 15,000 pages, and the TK312 around 12,000 pages, so a lighter department is never forced into the biggest box.

Treat this model as the department's shared workhorse. Advanced paper handling options support everything from custom sizes to heavy card stock, so the same machine that clears the morning's invoice run can also take on the odd heavyweight job without a second printer being wheeled in. In offices where one monochrome device carries a whole floor's output, that combination of throughput, standard duplexing and a network connection is exactly the point of the FS-4000DN.

Toner Cartridges for FS-4000DN

Which cartridge should you buy?

Work backwards from your monthly volume. The TK312 is the low-commitment starting point for a satellite office or a backup machine that prints in bursts. The TK322 suits a steady mid-size queue. The TK332 is the tier most FS-4000DN owners settle on: the longest interval between changes and the lowest cost per page of the three. Because every cartridge installs individually, nothing locks you in — you can run a TK312 this quarter and step up to the TK332 next time if the queue grows. High-volume sites usually keep one spare on the shelf so a toner-out warning never stops a deadline.

Chip, toner and everyday use

Each replacement cartridge carries the chip the printer reads to confirm the cartridge and track remaining toner, so seat the unit firmly until it locks and let the machine finish its recognition cycle before printing. Page yields here follow ISO/IEC 19752 at about 5% coverage; dense text and graphics will land lower. If pages start to fade near the end of a cartridge's life, remove it and rock it gently side to side to redistribute the toner — that often recovers enough print for the job in hand. Store spares flat, in their bags, away from heat and direct light.

Frequently Asked Questions

Which toner cartridges does the FS-4000DN use?

Three: the TK312 (about 12,000 pages), the TK322 (about 15,000 pages) and the TK332 (about 20,000 pages). They are the US versions of the cartridges sold in Europe as the TK-310, TK-320 and TK-330.

Is the TK-332 the same cartridge as 1T02GA0US0?

Yes. 1T02GA0US0 is Kyocera's US factory part number for the TK-332; the smaller two tiers carry the factory numbers 1T02F80US0 (TK312) and 1T02F90US0 (TK322). Ordering by either name gets you the same cartridge.

Can I switch between the three yield tiers?

Yes. The cartridges are interchangeable in the same machine, so you can move up or down a tier at any replacement — many owners try the TK332 after a standard cartridge to see how much longer the interval feels in practice.

What do the page yields actually assume?

They are rated per ISO/IEC 19752 at roughly 5% page coverage — a typical text page. Real-world results move with what you print: coverage-heavy reports and graphics use toner faster, light memos slower.
