Step-by-Step Solution

  1. Remove Cartridge: Open the front door and remove the toner cartridge.
  2. Clean Terminals: Gently wipe the gold-colored chip contacts with a lint-free cloth to remove any dust.
  3. Verify Chip Status: Ensure the chip is not chipped or bent. Verify the cartridge part number matches the B625 series.
  4. Firm Reinsertion: Put the cartridge back into the slot, pushing firmly until it sets into place.
