First, return the ink carriage of the digital printing machine to its initial position. Then, remove the waste ink tube from the waste ink bottle. Insert a 50ml syringe into the end of the waste ink tube and pull it back forcefully until all the waste ink is drawn out. After the ink is completely extracted, reinsert the waste ink tube into the waste ink bottle. It is important to note that when extracting the waste ink, do not release the syringe until there is no resistance. Do not remove the syringe immediately after the extraction is complete.
