CS-3550CI
The Copystar CS-3550CI is a Kyocera color multifunction machine wearing Kyocera's American badge — Copystar is the name Kyocera sells under in the United States, and this copier is the badge twin of the Kyocera TASKalfa 3550ci. The cartridges stocked on this page are the TK-8307 family: black is the TK-8307K (1T02LK0US0), and the three colors are the TK-8307C (1T02LKCUS0) cyan, the TK-8307M (1T02LKBUS0) magenta and the TK-8307Y (1T02LKAUS0) yellow. Each color is sold on its own, and all four together come as a 4 color set, in standard and Premium Quality listings.
One wrinkle is worth knowing before you order. This platform was sold under two badges, and the cartridge code printed in Kyocera's TASKalfa listings for these same models is TK8309, while the Copystar-badged shelf — this page — is organized under TK-8307 and the 1T02LK part numbers. Neither code is a misprint; they are the two listing generations for the platform. The cartridges you receive from this page are the TK-8307 ones named in the table below, so match the code on the cartridge you pull out of the machine, and if it reads 1T02LK or TK-8307 you are in the right place.

Which cartridge should you buy?
A shared color copier almost never empties evenly. Black does the everyday document work and usually runs out first, while one color may fade months before the others, so the single cartridges are the sensible default: replace the one the machine names and leave the rest in place. The 4 color set earns its shelf space when several colors are low together, when a machine is new to your office and you want a full spare set on hand, or when a heavy color job is coming and a mid-run stop would cost more than the cartridges. The set is listed twice — a standard and a Premium Quality version of the same four TK-8307 cartridges — so pick one listing and stay with it at reorder time to keep your own records simple.
Chip, toner and everyday use
Every TK-8307 cartridge carries a chip that the copier reads to identify the cartridge and track its toner level, so push each cartridge in until it seats fully and the machine confirms it before you close the cover. When a low-toner warning appears, the cartridge is near the end but not empty; ordering the replacement at the warning, rather than at the stop, is what keeps a department copier from sitting idle. Keep the empty cartridge until the new one is printing cleanly — its label is the surest way to confirm you ordered the right code — and store spares flat, sealed and away from heat and direct light.
Frequently Asked Questions
Is the Copystar CS-3550CI the same machine as the Kyocera TASKalfa 3550ci?
Yes — it is the same Kyocera platform sold under two badges. Copystar is Kyocera's brand in the United States, so the CS-3550CI and the TASKalfa 3550ci are badge twins, and this page covers the Copystar-badged machine with the TK-8307 cartridges stocked for it.
Should I order TK-8307 or TK8309 for this copier?
Order what is printed on the cartridge you are replacing. This page stocks the TK-8307 family — TK-8307K, TK-8307C, TK-8307M and TK-8307Y, numbered 1T02LK0US0 through 1T02LKAUS0 — while Kyocera-badged listings for the platform use the TK8309 code. Matching the full code on your old cartridge is the reliable way to land on the right shelf.
Only one color ran out. Do I have to buy the whole set?
No. Each TK-8307 color is sold as a single cartridge, so a spent cyan never forces you to replace healthy black, magenta and yellow cartridges. The set simply bundles all four for the times when several run low together or you want a complete spare set ready.
What is the difference between the two 4 color sets on this page?
Both sets contain the same four TK-8307 cartridges — one black, one cyan, one magenta and one yellow. One listing is the standard compatible set and the other is sold as the Premium Quality version of the same cartridges. Choose either; the cartridge codes your machine needs do not change.
More printers that use the same cartridges
One TK-8307 cartridge set feeds the whole platform, so the same four cartridges also fit the Copystar sibling and every Kyocera-badged twin on this list: CS-3050CI, TASKalfa 3550ci, TASKalfa 3050ci, TASKalfa 3051ci, TASKalfa 3551ci, TASKalfa 4550ci, TASKalfa 4551ci, TASKalfa 5550ci and TASKalfa 5551ci.
