Genuine OEM Kyocera TASKalfa 307ci Toners

The TASKalfa 307ci uses TK-5197 toner in four colors, with a choice between individual cartridges and a complete set. The set combines black, cyan, magenta, and yellow, while the single cartridges stay focused on one color.

Toner Buzz carries genuine Kyocera TK-5197 toner as both individual colors and a four-color set. The MK-3140 maintenance kit is a different type of supply, so it belongs to a service need rather than a toner purchase.
