FS-3820
The Kyocera FS-3820 is a no-nonsense monochrome laser printer for the small office that needs reliable black-and-white output day after day and nothing it does not. It feeds on a single long-life cartridge, the TK67 — the toner Kyocera's documentation labels the TK-65 — rated at up to 20,000 pages per ISO/IEC 19752. Model-coded listings of the same cartridge carry the factory numbers 370QC0KM and 370QD0KM. Twenty thousand pages between changes is the headline: replacements stay rare, and running costs stay predictable enough to budget once and forget.
Setup is simple and operation is straightforward, which is the entire design brief. Staff handling a daily workload never have to think about the printer — the consumables do not demand constant attention, the output is consistent, and the machine's separate long-life drum means the cartridge itself is toner-only, so a swap is the lightest maintenance event a laser printer can have.
Toner Cartridges for FS-3820
Which cartridge should you buy?
With up to 20,000 pages per unit, most small offices should think in years, not months: one installed cartridge plus one spare is a complete supply policy for a single FS-3820. The 2-pack formalizes exactly that. Multi-packs earn their place when several 3820-class machines share a storeroom — the 5 and 10 listings cut the per-page cost for a whole row of desks at once. The model-coded FS3820 listings and the TK67 listings are the same cartridge wearing different labels; match whichever number is on the cartridge you are replacing and the order will be right.
Chip, toner and everyday use
Ratings for this cartridge follow ISO/IEC 19752, so the 20,000-page figure assumes ordinary document coverage — heavy shaded forms will finish a unit sooner, plain correspondence later. When print finally lightens, remove the cartridge and rock it gently end to end; the toner bed settles and output usually recovers long enough to reach the spare. Because the drum on this model is a separate long-life unit, the cartridge you handle is toner only — lighter, cleaner and cheaper than an all-in-one design. Keep the spare sealed and stored flat indoors, and a changeover stays a two-minute job. Compatible cartridges on this page carry a 1-year warranty and 1-year returns.
Frequently Asked Questions
Which toner does the FS-3820 use?
The TK67 black cartridge — Kyocera's TK-65 in the printer documentation — rated for approximately 20,000 pages per ISO/IEC 19752.
Does the FS-3820 need a separate drum replacement?
The drum is a separate long-life unit on this model, and the cartridge is toner-only. In practice you replace just the toner when it runs low; the drum is not part of the routine cartridge swap.
Does this cartridge also fit the FS-3820N?
Yes. The FS-3820 and FS-3820N share the same print engine and the same TK67 cartridge, so networked and non-networked units draw from one shelf.
How many pages does one cartridge print before it needs changing?
Up to about 20,000 pages at standard coverage. For a small office that works out to a very long interval — which is why most owners keep a single spare rather than a stockpile.
