2. Turn Ink-solution 3-wayl valve to flush solution position (turn the handle upward).

7. Cover the wet-keeping frame the Print head.
8. Wrap the Print head unit with fresh-keeping polyethylene film.

fill the ink tubes and the Print heads by the cleaning solution, cover the Print heads by the wet keeping
frame and the wet keeping polyethylene films.
