Sharp AR 168S Supplies

The SHR AR-168NT cartridge has an approximate yield of 8000 pages.

Yes — the AR 168S uses a replaceable imaging drum: SHR AR-152DR.

When the AR 168S 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 SHR AR-168NT.
