CS-4550CI

The Copystar CS-4550CI is the mid-size color machine on Kyocera's larger color platform — Copystar is the badge Kyocera sells under in the United States, and this copier's Kyocera-badged twin is the TASKalfa 4550ci. Its cartridges are the TK-8507 family: the TK-8507K (1T02LC0US0) black, the TK-8507C (1T02LCAUS0) cyan, the TK-8507M (1T02LCBUS0) magenta and the TK-8507Y (1T02LCCUS0) yellow. All four are sold individually on this page, and together as a 4 color set in standard and Premium Quality listings.

Code discipline matters on this platform. TK-8507 is the cartridge generation stocked for the CS-4550CI; the smaller 3050ci and 3550ci color platform elsewhere in this catalog runs on the TK8309 family, which is a different cartridge for different machines. If you are cross-shopping the Kyocera TASKalfa section, where this copier's twins live, match the TK-8507 or 1T02LC code printed on the cartridge you remove. The listings below are the correct generation for this model, in Kyocera Mita titles because Copystar machines are Kyocera machines under the badge.

Toner Cartridges for CS-4550CI

Which cartridge should you buy?

Black is the workhorse on most color copiers — it covers the text on every page — so the black single is the cartridge you will reorder most, and worth keeping as a standing spare. The color singles let you answer the machine's message precisely: when it names the cyan, you replace the cyan and the other two colors keep working. The 4 color set fits a different moment — a newly installed machine, a full refresh after heavy color work, or a deliberate decision to hold one of everything. Note that the set is offered in two listings, standard and Premium Quality, both containing the same four TK-8507 cartridges.

Chip, toner and everyday use

Four cartridges means four chips, and the copier reads each one separately, reporting each color's level on its own. Change one cartridge at a time and let the machine recognize it before you move to the next, and keep the cartridge you removed until the replacement has printed a few clean pages — its label settles any question about which code and color came out. A color that is running low can print pale before it stops; that fading is the cartridge nearing its end, not a fault in the machine, and swapping in the fresh single restores the density.

Frequently Asked Questions

Is the Copystar CS-4550CI really a Kyocera machine?

Yes. Copystar is Kyocera's United States brand, and the CS-4550CI is the Copystar-badged version of the TASKalfa 4550ci platform. That is why the cartridges on this page are Kyocera Mita listings — they are the manufacturer's own product line for this machine.

TK-8507 or TK8309 — which code fits the CS-4550CI?

TK-8507. Order the TK-8507K family numbered 1T02LC0US0 through 1T02LCCUS0 for this model. The TK8309 family belongs to the smaller 3050ci/3550ci platform; cartridges from that family are not the ones stocked for the CS-4550CI.

Can I replace just the black cartridge?

Yes — every color is a separate cartridge and a separate listing here. Black, cyan, magenta and yellow each come out and go in independently, so a spent black never obliges you to touch colors that still have toner in them.

What separates the standard 4 color set from the Premium Quality set?

Only the listing. Both sets bundle the same four cartridges — TK-8507K, TK-8507C, TK-8507M and TK-8507Y — and either set gives the machine exactly what it asks for. Pick one version and reorder it consistently.

More printers that use the same cartridges

The same TK-8507 cartridges feed the rest of this color platform, Copystar-badged and Kyocera-badged: CS-5550CI, TASKalfa 4550ci, TASKalfa 4551ci, TASKalfa 5550ci and TASKalfa 5551ci.
