Check the belt rotating condition.
1. Make sure that the board clamp top
surface is approx. 0.5 mm lower than the
belt upper surface.
2. Close the machine safety cover and
cancel the emergency stop. Attach the
carriage if the machine is carriage type.
3. On the [Unit] - [Conveyor] screen, press
the [Conveyor In] button or [Conveyor
Out] button to turn on the conveyor
motor and check the belt rotation.
4. If the conveyor belt rotation is uneven or
if the belt deflects, adjust the tensioner
(pulley bracket) position again.

CAUTION
When the difference between the belt upper surface
and board clamp top surface is very little, the board
transfer error may occur easily. In this case, contact
YAMAHA sales representatives.
