ink and debris (clogged ink) from the nozzle plate until the nozzle plate is clean. Use a soft, clean and lint-free
cloth to loosen and remove the dirty ink and debris from the Clean Applicator to keep its surface clean and
wet again with Wash Liquid. Use one Clean Applicator for each color.
<Note>
The W3 and W4 Nozzles Plates of GT-381 are hard to be seen from the stop position. Move the Carriage to
the left by your hand to the position where you can clean the Nozzles easily.

with water.
