Compatible Magenta Cartridge for BizHub C224 C284

This magenta toner cartridge replaces the Konica Minolta TN-321M (A33K330) and fits BizHub C224, C284, C364, C224e, C284e and C364e copiers. It is an aftermarket unit manufactured in the USA and sold new as a single-pack replacement. The formulation targets OEM-level reliability and image quality for everyday colour printing.

25000-page colour yield at ISO 19798 5% coverage

Rated at 25000 pages per cartridge under the ISO/IEC 19798 test standard at five percent coverage, this cartridge handles regular office colour output with ample headroom. Heavy graphics or solid-fill pages will consume toner faster and reduce the practical page count below the rated figure. The black counterpart is rated separately at 27000 pages.

Upgrade from OEM TN-321M to lower per-page cost

This compatible cartridge directly substitutes the original Konica Minolta TN-321M supply, offering a lower cost per printed page while maintaining machine-tested compatibility. The jump is worthwhile for businesses printing consistent colour volumes who want American-made toner without the OEM price premium. It does not suit users needing the manufacturer's own cartridge for warranty stipulations.
