FS-3900DN
The Kyocera FS-3900DN is the networked version of the FS-3900D — a 35-ppm duplex monochrome workgroup printer built for shared, high-volume office printing. It takes the same two toner options: the standard Kyocera TK-312 (12,000 pages) and the high-yield Kyocera TK-322 (15,000 pages), both on Kyocera's long-life ECOSYS engine where toner is the only consumable.
Below you'll find compatible TK-312 and TK-322 cartridges for the FS-3900DN in single and multi-pack options. OEM-quality output, lifetime warranty, free shipping on orders over $49, same-business-day dispatch before 4 PM PST.

Frequently asked questions
What toner does the FS-3900DN use?
The standard TK-312 (12,000 pages) or the high-yield TK-322 (15,000 pages) — US versions of the TK-310/TK-320.
Is FS-3900DN toner the same as FS-3900D toner?
Yes. The FS-3900D, FS-3900DN, and FS-3900DTN all use the identical TK-312/TK-322 cartridges.
How do I choose between standard and high yield?
Heavy print volumes favor the TK-322 (fewer changes, lower cost per page); occasional printing favors the lower upfront cost of the TK-312.
Does this printer need a separate drum unit?
No. The ECOSYS long-life drum outlasts the printer under normal use — you only ever replace toner.
