adjustment program.

5.4.1 I/S Decompress

Overview
This printer is equipped with the ink supply mechanism that pressurizes ink constantly
even though the printer is turned off. Therefore, the following phenomena occur during
servicing.
If the joint of the ink supply tubes connected with the printhead is removed,
the ink in the ink tube flows out and contaminates the surroundings.
The ink flowed out from the joint of the ink supply tubes and the printhead
gets into the decompression tube of the ink tube.
At the leak check, the ink flows out from the joint of the ink tube and the
printhead or the nozzle of the printhead.
To prevent this from happening, execute this "I/S Decompress", and discharge ink in
the ink supply path via the Ink System (Cap) out of the printer. This minimizes the risk
of affect on servicing and quality.
Preparation
Before executing the I/S Decompress, make the following preparations:
Remove the Waste Ink Tray Assy to discharge the waste ink out of the
printer.(See "4.2.4.20 Waste Ink Tray Assy
Prepare a container to store the spilled ink from the waste ink

tube to prevent contaminating the surroundings.
P O I N T
Replace necessary parts after executing I/S Decompress. Make
sure to install the Waste Ink Tray Assy before start "Leak
Check".
When IS Decompress is executed, the auto cleaning setting
(ACL setting) is automatically turned off by the adjustment
program to minimize the ink consumption for ink charge after
assembling the printer. For this reason, record the setting
following the instructions of adjustment program, and restore
the setting accordingly on the "ink charge" screen before
returning the printer to the users.
