CS-1820
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, identical TK-18 toner cartridge, different logo on the front panel. Copystar was Kyocera's dealer channel branding in America, but the cartridges do not care about the badge. A single TK-18 stock covers both names without any compatibility guesswork for the IT staff managing them.
