  1. Hold the ink bottle upright and slowly turn the bottle cap to remove it.
  2. Insert the bottle into the filling port. The bottles are keyed for each color, so do not force them. Ink flows into the tank and stops automatically at the upper line. If ink does not flow, lift and reinsert the bottle.
  3. When the tank is full, remove the bottle and close it securely with its cap, then close the ink tank cap.
  4. Repeat for each tank you need to refill, then close the ink tank cover and lower the scanner unit.
  5. Select Maintenance > Fill Ink and follow the on-screen instructions to reset the ink levels for every ink you refilled.

If the ink levels are not reset for every ink you refilled, you may get an error message or the levels will not change on the LCD screen.
