 It is recommended that the ink in the Ink Supply Tank should be discharged completely
before proceeding to disassembling/reassembling.
 After all the reassembling work is complete, the discharged ink of each color should be
refilled back to the Ink Supply Tank before performing the adjustment. Confirm the
colors indicated on the film of the Ink Supply Tank so as not to mistake them, and make
sure to refill each ink back to the correct tank from the corresponding ink supply hole.
