Coolant is a used to maintain the temperature of the ink in the printheads.
It is important to check the coolant bottle, located in the Primary Ink Bay, to see if the level is low. Keep the coolant level up to ensure proper ink temperature.
The Accessory Pack that ships with a new printer contains a 2 liter container of coolant. During an install the coolant system requires 1.8 liters to fill the coolant bottle and lines. We suggest that you order more coolant from your sales representative so that you will have some when you need to top up the system.
