Summary

How to place the ink tank assy when disassembling or reassembling
The film under sealing film attached on the Ink Supply Tank Assy of this printer is ventilation film. The ink in the ink tanks is vented to atmosphere through this film to keep ink supply to the print head stable. If the film gets wet with ink, the ink in the tanks is not properly vented and printing may not be capable. In order to prevent this from occurring, make sure to place the Ink Supply Tank Assy as shown below after removing it.
How to place the ink tank assy when disassembling or reassembling 01
Do not place the Ink Supply Tank Assy with its film side down. Otherwise, ink in the Ink Supply Tank Assy may reach and cover the ventilation film, and the printing failure may occur.

It is recommended that the ink in the Ink Supply Tank should be discharged completely before proceeding to disassembling or 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.
