LIQUID SUPPLYING APPARATUS, LIQUID EJECTING APPARATUS AND PRESSURE CONTROL METHOD |
摘要 |
A liquid supplying apparatus includes: a first flow channel configured to be switchable between a state of communication with a liquid supply object and a state of noncommunication with the liquid supply object; a first pressure applying device which applies pressure to liquid in the first flow channel; a first pressure absorbing device which absorbs a pressure fluctuation of the liquid in the first flow channel; a first measuring device which measures a pressure increase value in the first flow channel when the first pressure applying device is operated under a standard operating condition in which pressure in the first flow channel varies relatively moderately in proportion to a liquid feed amount to the first flow channel in the state of noncommunication where the liquid supply object and the first flow channel are not communicated with each other; a comparing device which compares the pressure increase value measured by the first measuring device with a predetermined pressure increase target value; and a pressure controlling device which controls the first pressure applying device according to a comparison result of the comparing device so as to correct the pressure applied into the first flow channel. |
