3. System Maintenance

• Data in

• USB access

• HOME

• Status check (When lit, R->G->B->R->G->B is repeated at 500 ms intervals)

• BACK/MENU

• FAX

• SD access

2. Key check

Check pressing hard keys other than the [HOME] key on the control unit. When a key is

depressed, the corresponding key displayed on the control unit is shown highlighted.

If a foot switch is fitted, while the switch is depressed, the "FOOT SW" column is highlighted.

When the [End] key is depressed, the display returns to the self-diagnosis top screen (the Back key

works as a key check, so it cannot be used as a key to return to the self-diagnosis top screen).

3. LCD Check

Whenever the screen is touched, the display cycles through All-white -> All-black -> All-green

-> All-blue -> End in full screen view, and the display status of each color is visually verified.

By cycling through all the colors, the LCD check is completed, and the display returns to the self-

diagnosis top screen.
