Changing height procedure

Press the ENTER key several times on the LOCAL mode screen to bring up the information screen.
Please check the head height from there.
2. Move the head to the platen
(1) Press the FUNC1 key and execute [Maintenance] -> [Station Maintenance] -> [Carriage Out].
(2) Open the front cover and manually move the head to the center of the platen (table).
3. Adjust the head to the desired height
Turning the height adjustment lever on the right side of the head clockwise raises it,
and counterclockwise lowers it.

lever reaches to the M position.
