How to Replace Cartridge(s)

  1. Before you begin the refilling of ink tanks, make sure that the machine is powered on.
  2. Lift the scanner unit. Open the ink tank cover and then open the cap of the ink tank you need to refill.
  3. Take the new ink bottle upright and then carefully remove the cap. Avoid shaking or squeezing the bottle.
  4. Position the top of the ink of the bottle along the slot in front of the filling port. Then, carefully stand the bottle up to insert it.
  5. Allow the ink to fill the tank and avoid squeezing the bottle. The ink will flow into the tank and will automatically stop when the ink is filled to the upper line.
  6. Remove the ink bottle and replace its cap when the ink tank is full.
  7. When you’re finished refilling all the empty tanks, close the scanner unit.
