Refilling the Cooling System
The cooling system circulates cool water through the printhead mounting
blocks to aid in maintaining optimum printhead temperature.
During printer operation, the water level must stay between the HIGH and
LOW indicators. If the water level is below the LOW indicator, the cooling
system will become ineffective. It is recommended that you check the water
level periodically and add water if necessary
Caution: Only use non-conductive, distilled water. Other liquid can cause
oxidation or corrosive damage to the cooling mechanism.
1 Remove the reservoir cap from each cooling drive, and then fill them
with the supplied distilled water. Ensure that the water level is between
the HIGH and LOW indicators.
