Genuine OEM Kyocera ECOSYS M3550idn Toners
The ECOSYS M3550idn separates black toner from its imaging and maintenance parts. TK-3122 is the toner cartridge; DV-3100 is the developer, DK-3130 is the drum, and MK-3132 or MK-3140 identifies a maintenance kit.
Toner Buzz carries genuine Kyocera TK-3122 black toner along with those service parts. Choose TK-3122 for the toner supply, and use the developer, drum, or maintenance-kit code only when that separate component is needed.
