Fill the Coolant Reservoir
Fill the Coolant Reservoir
Introduction
The coolant is a thermal fluid used to maintain the temperature of the ink in the
printheads and ink reservoirs on the carriage. Temperature control of the ink is
required in order to achieve the correct ink viscosity, which affects the jetting
velocity of the ink and thus the quality of printed images. The coolant is pumped past
a heater that has a thermostat to maintain the coolant temperature. The coolant flows
in series through each of the printheads and then returns to the coolant reservoir.
Each printhead has an internal sensor that provide temperature feedback. The
reservoir block also has a sensor to provide feedback. The coolant reservoir contains
an optical level sensor. A sight tube on the side of the gantry, at the opposite end from
the carriage, displays the level of coolant in the reservoir. The operator must
maintain this level.
Purpose
If the coolant level is low, the ink and printheads cannot be maintained at the proper
temperature. Periodically check the level of coolant and add more coolant if it is
below the center of the sight tube.
When to do
Check the coolant level sight-tube, located at the side of the gantry, to verify that the
level is low. When filled to the proper level, the fluid will be at the center of the
sight-tube. If the level of coolant is lower than the center, it is time to fill it. Keep the
coolant at the correct level to maintain the proper ink temperature as the coolant is
important to that process.
Before you begin
Verify that the coolant level is below the center of the sight-tube. If it is at the center
or higher, it is not necessary to add coolant. The sight-tube is located on the side at
the right end of the gantry Operator Interface Hardware .
Required tools
Syringe (supplied with Starter kit)
Wear gloves (coolant will not harm the skin, but gloves are recommended).
