FS-3900DN

Kyocera FS-3900DN printer

The Kyocera FS-3900DN is a departmental monochrome laser printer with full network sharing and automatic two-sided printing as standard equipment. Unusually for its class, it offers a genuine two-step yield choice: the standard TK-312 at 12,000 pages, or the high-yield TK-322 (1T02F90US0) at 15,000 pages; the standard cartridge's factory number is 1T02F80US0. Gigabit networking keeps large jobs moving even when several users print at once.

This is the hub end of the FS line — a machine bought to sit in the middle of a department and absorb whatever the day brings. The ECOSYS design keeps the drum as a long-life internal component, so the supply routine never grows beyond toner, and the two cartridge tiers let the office match purchasing to reality: standard yield for moderate queues, high yield where the printer never really cools down.

Which cartridge should you buy?

The standard-versus-high-yield call turns on volume. The TK-312 at 12,000 pages carries a lower upfront cost and suits a department whose printing comes in waves. The TK-322 stretches each change to 15,000 pages, which lowers the cost per page and, just as usefully on a shared machine, reduces how often anyone has to stop and swap a cartridge. Both ratings follow ISO/IEC 19752 at about 5% coverage; if your output is forms and dense reports, plan on the high-yield cartridge and keep a spare — the queue behind this printer will thank you.

Chip, toner and everyday use

Each cartridge's chip reports its level to the FS-3900DN, and because the printer is networked, that information reaches whoever manages supplies before it becomes a user complaint. On a fading cartridge, a gentle rock side to side redistributes toner and typically restores even coverage for its final stretch. Avoid running a shared departmental printer deep into an empty cartridge — streaked output on other people's documents is how a toner errand becomes an IT ticket. Keep the spare sealed and flat until the day it is needed.

Frequently Asked Questions

What toner does the FS-3900DN use?

Either of two black cartridges: the standard TK-312 (12,000 pages) or the high-yield TK-322 (15,000 pages). They are the US versions of the TK-310 and TK-320 named in European documentation.

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 and TK-322 cartridges, so one spare shelf can cover every variant on the floor.

Does this printer need a separate drum unit?

No. The ECOSYS long-life drum is built to outlast the printer under normal use, so toner is the only consumable you replace — there is no drum line item in this machine's running costs.
