ABSTRACT:
An ink liquid supply system for an ink jet system printer includes a constant flow rate pump and a pressure accumulator for removing a pressure pulsation or ripple created by the constant flow rate pump. In order to stabilize the constant flow rate operation and to shorten the preparation period of the system when the system operation is started, a temperature compensation or sensitive system is provided for varying the ink liquid pressure within the pressure accumulator. The temperature compensation system includes a bimetal element for varying the pressure to be applied to a resilient member included in the pressure accumulator. The pressure adjusting operation is continuously conducted even when the ink jet system printer does not operate.
