14. REPLACEMENT AND ADJUSTMENT

14.1 DF Belt Drive Motor Speed Adjustment

NOTE: This adjustment should be done whenever the DF main board is replaced.

ADJUSTMENT STANDARD:

2,600 ± 30 rpm

1. Turn off the main switch.

2. Remove the DF cover (4 screws, 2 collars).

3. Lower the DF unit.

4. Turn on DIP SW 101-1, 2, and 4 [A].

5. Turn on the main switch.

• The belt drive motor will start turning, and the left two digits of the motor speed will be

displayed in the original counter.

• Press SW 101 [B] on the DF main board to display the second two digits of the motor

speed.
