Kyocera Mita CS7004i Supplies

The KYO TK6347 cartridge has an approximate yield of 40000 pages.

When the CS7004i 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 KYO TK6347.
