The cylindrical design of the Konica Minolta TN512K makes it an ideal candidate for remanufacturing and the results are great. The few internal components in the Konica Minolta TN-512K 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 black toner powder that gives great quality prints for the estimated 27,000 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 A33K152 toner cartridge.
