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 Printhead 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.
