Setting
NOTE: The belt drive speed adjustment is required when the main board is
replaced.
1. Turn off the main switch.
2. Check that DIP switch 101 is set for the normal setting as follows:
101-1
ON
3. Turn on the main switch and DIP switch 101-2 and -4.
4. While turning on the lift switch manually, adjust the belt drive motor speed
using VR101 [A] so that both the Insert Original indicator [B] and Auto
Feed indicator [C] turn off.
NOTE: a) When the Insert Original indicator lights, turn VR101 clockwise
to reduce the motor speed.
b) When the Auto Feed indicator lights, turn VR101
counterclockwise to increase the motor speed.
c) Confirm that both indicators remain off for approximately 5
seconds in order to stabilize the motor speed.
5. Turn off DIP switch 101-2 and -4.
NOTE: Do not use VR106. This variable resistor is for adjusting feed-out
motor speed. This is preset by the vendor.
