 When separating the Printhead and the Ink Supply Unit, make sure to perform "3.2.7
Ink Leak Check (p79)" to check if ink is leaking.
 After disconnecting the Printhead and the Ink Supply Unit, ink may spill over even if the
pressure is released. Therefore, be careful not to contaminate the surroundings.
 Make sure that the buffer is being deflated before the print head is removed, as shown
below.
If the buffer is inflated, make sure to perform the “Ink pressure release” again, because
the ink is not discharged condition.
