METHOD OF THERMAL DEGASSING IN AN INKJET PRINTER |
摘要 |
A method of reducing air in an ink passageway in an inkjet printer by pressurizing a thermally actuated degassing unit that includes an air chamber, venting air through a check valve configured to allow air to vent from the air chamber to ambient when the pressure in the air chamber exceeds ambient air pressure by a predetermined amount The pressurizing is performed by heating an element inside the air chamber. A power supply is connected to the heating element, and power is applied to the heating element during a first time interval to increase the pressure in the air chamber above ambient pressure. Gas is vented from the check valve which allows the heating element to cool during a second time interval to reduce the pressure in the air chamber below ambient pressure. Gas is then drawn from the ink passageway through the membrane into the air chamber. |
