  2. Open the scanner unit to access the cartridge carriage.
  3. Unlock the blue levers and carefully pull out the printheads.
  4. Wipe the gold contacts gently with a dry, lint-free cloth.
  5. Insert the printheads back into the carriage and lock the levers.
  6. Power on and run a nozzle check from your computer.
