KM Series

The KM Series pages cover the older Kyocera Mita multifunction machines — the copier-based systems that anchor a copy room rather than sit on a desk. Twenty-six model pages sit under this series, and they draw on a short list of cartridge families: the TK-421 (370AR011) that feeds the KM-2550 class, the TK-132 (1T02HS0US0) shared with smaller machines, the TK-677 (1T02H00US0), and the legacy 370AB011 listings also sold under the TK410 name.
These are departmental machines in the plainest sense: the KM-3050 class was built to serve a whole floor's copying, printing, scanning and faxing from one floor-standing chassis, and that duty explains the shape of this shelf. Cartridges are bought in multiples — the table below is heavy with 3-packs, 5-packs and 10-packs — because a machine that serves forty people does not wait for a single spare to arrive. The KM-2550 also has a twin outside this series: the same machine was sold as the Copystar CS-2550, and both badges take the TK-421.
Popular cartridges for the KM Series
Every product on this series shelf is listed below — all 24 listings across the five families these machines use.
Which cartridge should you buy?
Match the machine, then the pack size. Open your model page from the directory below — KM-3050 for the departmental flagship class, KM-1820 for the compact end — and the family named there is the one to order. After that, the only real choice is quantity: singles keep a little-used machine supplied, while the multi-packs in the table suit machines whose toner is a weekly line item. If your machine wears a Copystar badge instead, do not shop by the badge; the KM and CS twins share cartridges, and the model number is the part that matters.
Chip, toner and everyday use
A copy-room machine announces a wrong cartridge the hard way: it stops a shared queue. Check the full code on the old cartridge's label before ordering, and keep the removed cartridge until the new one has run clean copies, so a defect can be traced to the part that changed. New cartridges stay sealed until the day they are fitted; toner that has sat open in a humid copy room clumps and prints unevenly. Every compatible cartridge on this page is covered by a 1-year warranty and 1-year returns.
Frequently Asked Questions
Are KM models the same as ECOSYS models?
No. KM is the older Kyocera Mita badge generation, and ECOSYS is the current line. A few cartridge families appear in both trees — the TK-132 is one — but most do not carry over, so a code that fits an ECOSYS machine is not promised to a KM machine. The model page settles it.
Why does one cartridge fit so many KM models?
The KM range was built on shared engines, so a single family can serve a whole class of machines: the TK-421 covers the KM-2550 class, and the TK-132 covers several of the smaller models. That sharing is also why this series shelf holds only five families for twenty-six model pages.
My cartridge says 370AB011 but a listing says TK410. Is it the same part?
Yes. The two names are generations of the same labeling habit: the long 370AB011 number is the original part number, and TK410 is the short name the same cartridge is sold under. The table above lists both naming styles, and either search lands on the same family.
How many cartridges should a copy room keep on hand?
At least one full change ahead of the machine. A shared system that runs dry stops every department that uses it, and the multi-packs in the table — up to 10-packs on the 370AB011 line — exist for exactly that stocking pattern. Light-use machines can stay on singles.
