CS-3050CI

The CS-3050CI is a color multifunction copier sold under the Copystar name, Kyocera's badge in the United States. This page carries its toner in the TK-8307 generation: black is TK-8307K, part number 1T02LK0US0; cyan is TK-8307C (1T02LKCUS0); magenta is TK-8307M (1T02LKBUS0); and yellow is TK-8307Y (1T02LKAUS0). All four singles are stocked here, along with two four color sets. One caution before ordering: the Kyocera-badged TASKalfa versions of these machines are listed with the TK-8309 generation instead, so the code on the cartridge you remove — not just the model name — is the thing to match.

This is a departmental color machine, the kind that sits at the center of a workgroup's printing, copying and scanning, and its toner planning follows departmental habits: black turns over steadily, colors in waves when projects land. A full set on the shelf keeps the machine whole when a big color job drains two cartridges in the same week, while the singles let a supply manager top up only what the level display is complaining about. Because the CS badge and the TASKalfa badge split the same platform into two cartridge generations, fleets that run both nameplates keep the TK-8307 boxes for these Copystar units clearly separated from the TK-8309 stock.

Which cartridge should you buy?

For a single low color, buy the single — each of the four is stocked individually and changes independently. For a machine that has run several colors down together, or for a fresh spare shelf, the four color set replaces the full set in one box and keeps all four cartridges the same age. The premium set contains the same four cartridge codes in the premium-quality grade of the line, for offices that standardize on that grade. Either way, confirm the code on the outgoing cartridge starts TK-8307 before you order: that one check is what separates this Copystar page's stock from the TK-8309 generation sold for the Kyocera-badged twins. Every compatible cartridge here carries a one-year warranty and one-year returns.

Chip, toner and everyday use

The copier identifies each cartridge by color position, so work through a change one slot at a time and let the machine register the new unit before moving to the next. Rock a new cartridge gently side to side before fitting it, pull the seal cleanly, and keep fingers off the drum surface. Color cartridges waiting on the shelf should stay sealed, upright and out of direct light. On a shared machine it pays to write the install date on the box end of the spare that replaces it — when output fades months later, that small note tells you at a glance whether the cartridge is truly spent or the problem sits elsewhere.

Frequently Asked Questions

Does my CS-3050CI take TK-8307 or TK-8309 toner?

This Copystar-badged machine is stocked with the TK-8307 generation on this page. TK-8309 is the generation listed for the Kyocera-badged TASKalfa versions of the platform. The two generations belong to the two badges, so order by the code printed on the cartridge you take out.

What is the difference between the two four color sets?

Both sets hold the same four cartridges — one each of black, cyan, magenta and yellow in the TK-8307 family. The premium set is the premium-quality grade of the line; the standard set is the regular grade. Fit and contents are otherwise identical.

Can I replace only the black cartridge?

Yes. The black is sold on its own as the TK-8307K, and each color changes independently, so a spent black never means buying colors you do not need yet.

Which other machines use the TK-8307K black cartridge?

The black cartridge is shared across the wider family listed below — the Copystar CS-3550CI and the TASKalfa 3050ci through 5551ci generations of the same platform, whose own pages list their badge's generation of the cartridge.
