 About I/C Decompress
This printer is equipped with the ink supply mechanism that
pressurizes ink constantly even though the printer is turned off.
Therefore, if the joint of the ink supply tubes connected with
the printhead is removed without discharging the ink in the ink
tube, the ink leaked from the junction point of the Ink Supply
Tube Assy and the Printhead might contaminate the
surroundings.
If the ink gets into the Decompression tube of the Ink Supply
Tube Assy, it may adversely affect the ink supply to the
Printhead. To prevent this from happening, make sure to
execute
"5.4.1 I/S Decompress (p238)" and discharge ink in the
ink supply path before disassembling, then remove the
Printhead.
