Simultaneously send the ink from all six colors contained in the ink tube
unit to the maintenance cartridge.
Send the ink in the ink tanks to the cartridge one color at a time.
Repeat Step 2 for the remaining five colors.
If all of the ink passages are opened (ink tank is not installed, ink supply
valve is opened, and printhead lock lever is opened) when ink fills the ink

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.
