Konica Minolta Bizhub Pro 4052 Supplies

The KNI AAE1030 cartridge has an approximate yield of 25000 pages.

When the Bizhub Pro 4052 throws a "Supply Problem" error, the printer often simply can't read the cartridge chip. Give it a full power-cycle, take the cartridge out and put it back securely, and lightly buff the metal contacts with a dry, lint-free cloth. If it persists after all that, the cartridge is likely worn — install KNI AAE1030.
