There are two ways to drain the ink passage of inks: automatic and manual.
Be sure to drain the ink from the ink passage to prevent ink leakage before disassembling any component of the ink passage or reshipping the printer.
1. Automatic Ink Drain
Execute Automatic Ink Drain by selecting Maintenance > Move Printer from the main menu.
Execute Automatic Ink Drain once again if the printer shuts down due to a power failure or any other trouble before the operation completes.
2. Manual Ink Drain
Drain the ink passage of inks manually if any electrical component in the printer fails or firmware malfunctions or if the printer fails to be powered on.
1) Remove right circle cover (L), right circle cover (S), right side covers, ink tank cover units. See Disassembly/Reassembly > Points to Note on Disassembly/
Reassembly > External Covers.
2) Remove the ink tanks.
3) Move the carriage to above the platen. See Disassembly/Reassembly > Points to Note on Disassembly/Reassembly > Opening the caps and moving the wiper unit.
4) Release the printhead fixer lever.
5) Open the ink supply valves to allow the inks to flow into the subtanks.
