6. Maintenance
A. Only Color Ink is printed with GT-381/GT-361
Preparation before storage
Execute White Tube Cleaning; select [ All Whites ] to retrieve White Ink. Refer to "6-2-3. White Tube Cleaning
(Once a week)" for more details. After Tube Cleaning is finished, insert 'almost empty but not expired' White Ink
Cartridges on the Slots, with Tubes filled with Maintenance Solution.
<Note> White Ink is fired for maintenance even when you print with only Color Ink.
<Note>
・ Do not use the White Ink Cartridges that you have used in storage; the White Ink and Maintenance Solution
are being mixed and the whiteness will be decreased.
・ The menu [ GT-341 mode ] is for GT-381/GT-361 with no White Print Heads mounted. If you select this menu
with White Print Heads mounted, the White Print Heads will surely get damaged by no maintenance.
Maintenance once in every two weeks
Be sure to execute this maintenance process once in every two weeks. Keep the Tubes filled with fresh
Maintenance Solution.
(1) Execute Tube Cleaning ONE BY ONE individually, not to retrieve the Maintenance Solution into the
Maintenance Cartridge. Refer to " 6-2-3. White Tube Cleaning (Once a week)".
<Note>
Execute Tube Cleaning ONE BY ONE individually, or the old Maintenance Solution will be retrieved into the
Maintenance Cartridge and give serious damage.
(2) Fill the Tubes with fresh Maintenance Solution by repeating the step 1 in the above.
(3) After you confirm that the Tubes are full of Maintenance Solution, then install 'almost empty but not expired'
White Ink Cartridges on the Slots.
Restart the White Ink printing
Reinstall the White Ink by referring the steps in "C. Restart after 2 weeks' storage" in this chapter.
