HOW TO PLACE THE INK TANK ASSY WHEN DISASSEMBLING/
REASSEMBLING
The Ink Supply Tank Assy of this printer has an air release hole on the upper part.
The ink in the ink tanks is vented to the atmosphere through this hole to stabilize ink
supply to the Printhead. If the Ink Supply Tank Assy is tilted, the ink in the tanks may
leak from the air release hole. If the air release hole is sealed up with the leaked ink,
ventilation to the atmosphere cannot be done properly and the print quality may be
affected adversely.
In order to prevent this from happening, make sure to place the Ink Supply Tank Assy
as shown below after removing it.
