  • For a 10-color machine prepare about 700 liters. If your color tanks are empty (and cleaned thoroughly with water), you may fill the required amount of cleaning paste into every color tank.
  • Optionally you may use the clear paste tank for the complete amount of cleaning paste: Fill the color supplies one after the other from the clear paste tank.
