FS-3900DTN

Kyocera FS-3900DTN printer

When a single paper tray is not enough, the Kyocera FS-3900DTN answers with its twin-tray configuration layered on top of duplex and networking — extra paper capacity for uninterrupted long runs. The toner story stays deliberately simple: the standard TK-312 (TK312) at about 12,000 pages, or the longer-running TK-322 (TK322) at about 15,000 pages, the same pair as the rest of the FS-3900 family, rated per ISO/IEC 19752.

The DTN is made for departments that print through reams of paper without stopping to reload trays: two trays can hold two stocks at once, or one long run's worth of the same paper, while the engine keeps pace. Optional finishers can be added later for offices that eventually need stapling or sorting — and none of that hardware growth touches the supply shelf, which stays at two cartridge numbers for the machine's whole life.

Sizes printed as plain text are not currently orderable from this page; the linked sizes are sold here. Both cartridges appear in single and multi-pack quantities, in standard and high-yield ratings.

Which cartridge should you buy?

Long runs argue for the high yield. A twin-tray machine is bought to keep printing, and the TK322's roughly 15,000 pages per cartridge is the rating that matches that intent — fewer interruptions, and typically the lowest cost per page for offices printing thousands of pages a month. The TK312 remains the sensible pick where volume is steadier and lower, or where several FS-3900 variants share one shelf and standardization matters more than the last increment of yield. In bulk, this page's linked routes are the TK312 5-pack and the TK322 3-pack. All cartridges are compatibles with a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Twin trays change how a department thinks about paper, not toner: the cartridge routine is the same as any FS-3900. Both cartridges are chipped, so levels show on the machine before they become a problem. Ratings assume about 5% coverage — a floor running dense, full-text documents will cycle cartridges faster than the numbers suggest, which is worth remembering when you set a reorder point. Rock a fading cartridge gently side to side to level its remaining toner, and keep the spare where the long runs happen, not in a distant storeroom.

Frequently Asked Questions

What is the toner difference between the FS-3900D, FS-3900DN and FS-3900DTN?

None. All three use the identical TK312 and TK322 cartridges. The letters describe printer configuration — duplex, networking, twin trays — not consumables.

Which yield is more economical for the FS-3900DTN?

For a department printing thousands of pages a month, the TK322 high yield: its 15,000-page rating spreads the cartridge cost over more pages and cuts changeovers. Lighter floors can stay with the TK312.

If I add a finisher later, does my toner change?

No. Finishers handle paper after printing — stapling and sorting — and have no effect on the cartridge. The TK312 and TK322 remain the machine's two toner options.
