1. Make sure that the board clamp top
surface is approx. 0.5mm lower than the
belt upper surface.

carriage, set the carriage.
3. On the [Unit] - [Conveyor] screen, press
the [Conveyor In] button or [Conveyor

slack in the belt, adjust the position of
the tensioner (pulley/pulley bracket) that
tension is applied, and then check the
rotation 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 representative.
