6-2-3. White Tube Cleaning (once a week)
This menu washes away the pigments inside the Tubes and Print Heads. When you execute this menu all-in-one
time, GT-381 for four Tubes, GT-361 for two Tubes, you can retrieve the White Ink before Tube Cleaning. It takes
time but you can save the cost. If you select the Tube one by one then the White Ink will not be retrieved. Follow
the indications on the Display and operate with Maintenance Cartridge.
<Note>
If you leave GT-3 printer unused for more than two weeks, execute White Tube Cleaning for storage. Insert
Capping Cartridges (option) in place of White Ink Cartridge. See "6-2-5. Required Maintenance for the Long
Storage".
<Note>
Confirm the firmware should be ver. 2.10 or higher.
When you execute White/Color Tube Cleaning, be sure to use the clean bottle and fresh Maintenance Solution;
follow the steps below when you fill in the bottle. Clean the inside regularly.
(1) Throw away the old Maintenance Solution (1) left in the bottle.

slowly to rinse the inside.
