Liquid refilling method, liquid supplying apparatus, and liquid jet recording apparatus |
摘要 |
<p>A method for refilling liquid to a liquid supply path is provided with a sub-tank for supplying the liquid by retaining it temporarily and inducing the air outside into the sub-tank. This method comprises the steps of making the sub-tank a closed space and filling the liquid while reducing pressure in the sub-tank. With the application of this method, liquid can be supplied stably. Also, by use of a pump serving as means for generating negative pressure in the sub-tank, which can be installed on a path different from the liquid supply path, the structure of the liquid supply path becomes simpler to make it easier to avoid liquid leakage or other operational difficulties for the enhancement of a stabilized supply of liquid. <IMAGE></p> |
