A. White Tube Cleaning (Once a week)
<Note>
Confirm the firmware should be ver. 2.10 or higher.
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 "7-2. Required Maintenance for the Long
Storage".
