CS-1820

Kyocera CS-1820 printer

The Copystar CS-1820 is Kyocera's US-market badge on the same 18-series monochrome hardware sold elsewhere as the KM-1820 — identical engine, different logo on the front panel — and the badge is the only thing that changes. Both names run on a single cartridge, the TK18 black toner (Kyocera's TK-18 designation), rated for up to 7,200 pages per ISO/IEC 19752. This page stocks it from a single cartridge up to a 10-pack.

Copystar was Kyocera's dealer channel branding in America, which is why the same machine wears two names depending on who sold it. For the people managing supplies, that history is a convenience: one TK18 stock covers both badges with no compatibility guesswork, and a cartridge pulled from the shelf for a KM-badged unit is the same cartridge a CS-badged unit takes. IT staff running a mixed row of 18-series machines order one part number and stop thinking about which logo is on which desk.

Which cartridge should you buy?

There is only one cartridge decision on this page — how many at a time. A single TK18 suits a lone machine with light, occasional output. Offices running several 18-series units, under either badge, usually settle on the 3 or 5 packs: the per-cartridge cost steps down as the pack grows, and a shared shelf means no single desk can run the stock out. The 10-pack is fleet buying, for a row of machines printing every day. Whichever size you pick, the cartridge itself never changes, and each one is a compatible covered by a 1-year warranty and 1-year returns.

Chip, toner and everyday use

The TK18 is a toner-only cartridge: the drum on this model is a separate long-life component, so a toner change is just a toner change — lift the spent unit out, seat the new one, and print. If pages start coming out faint before the cartridge is truly done, take it out and rock it gently side to side to redistribute the toner clinging to the walls, then run it again; that trick often recovers a useful number of pages. The 7,200-page rating assumes roughly 5% coverage, so dense documents will land lower. Store spares in their packaging, flat and away from heat, and they will be ready when a badge of either name asks for one.

Frequently Asked Questions

Does the CS-1820 take the same toner as the KM-1820?

Yes. The two names are the same 18-series hardware under different badges, and both use the TK18 black toner cartridge. There is no CS-specific variant to hunt for.

How many pages does one TK18 print?

Up to approximately 7,200 pages, rated per ISO/IEC 19752 at standard coverage. Real-world counts move with what you print — heavy, dark pages use toner faster than light office text.
