FS-3900D
A step up in Kyocera's departmental range, the FS-3900D combines built-in duplex with a faster engine for high-demand office floors that never slow down. The TK-310 toner delivers about 12,000 pages per cartridge, so heavy users are not constantly swapping supplies in the middle of the week. Built for the environment where the printer rarely gets a quiet moment to rest. Expandable paper options let it grow alongside the department instead of being replaced by it.
| Cartridge | Color | Page yield* |
|---|---|---|
| TK-312 | Black | 12,000 pages |
| TK-322 | Black | 15,000 pages |
Per ISO/IEC 19752 at ~5% coverage. EU equivalents: TK-310/TK-320.
Frequently asked questions
Which toner cartridges fit the Kyocera FS-3900D?
Two options: the standard TK-312 (12,000 pages) and the high-yield TK-322 (15,000 pages). Both are the US versions of the TK-310/TK-320.
Should I buy TK-312 or TK-322?
If you print heavily, the TK-322's 15,000-page yield means fewer swaps and a lower cost per page. For lighter use, the TK-312 costs less upfront.
Can I use TK-332 in the FS-3900D?
No. The TK-332 (20,000 pages) is built for the FS-4000 series; the FS-3900D takes TK-312 and TK-322 only.
Are the high-yield cartridges also compatible (non-OEM)?
Yes. Both the TK-312 and TK-322 options on this page are new compatible cartridges engineered to OEM specifications.
