he cylindrical design of the Konica Minolta A33K352 makes it an ideal candidate for remanufacturing and the results are great. The few internal components in the Konica Minolta TN-512M mean very little has to be replaced, and when it does the compatible components work just as well.In addition to the above, our manufacturers have gone to great lengths to produce a compatible magenta toner powder that gives great quality prints for the estimated 26,000 page life of the cartridge. Compatible with the Konica Minolta Bizhub C454 and all other printers listed on this page, we strongly recommend the remanufactured Konica Minolta TN512M toner cartridge.
