■ Changing the Height of the Sublog Board

NOTE:
When installing the Sublog Board, it needs to be installed parallel to the Main Controller
PCB in order to prevent connection error of the connector connecting the Main
Controller PCB and the Sublog Board.
This machine utilizes the height of the spacer (short), and how to replace the spacers
with each other is shown below.
2) Disassemble the Sublog Board [1], and replace the spacer (short) [1] and the spacer (long)
[3] with each other.
• 1 screw [4]
CAUTION:
Because the screw [4] is a molded part, do not tighten it too much. Otherwise, it may be
damaged.
