If all of the ink passages are opened (no ink tank is installed, the ink supply valve is opened, and the print head lock lever is opened) when an ink tube is
filled with ink, the ink in the ink tube may reverse-flow due to the difference in the water head, and ink may leak from the ink supply needle. Therefore,
do not open all of the ink passages at the same time when the ink tube is filled with ink.
