Check the belt rotating condition.
1. Make sure that the board clamp top
surface is approx. 0.5mm lower than the
belt upper surface.
2. Close the machine’s safety cover, and
cancel the emergency stop. If the
machine could be equipped with a
carriage, set the carriage.
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 rotation speed fluctuates or there is
slack in the belt, adjust the position of
the pulley that tension is applied, and
adjust the pulley’s position again.
