2.3 Adjusting the conveyor belt tension
The conveyor moves by belt drive to load boards ready for printing and to unload the finished boards. If the
conveyor belts are too loose, they may slip on the pulleys causing unstable board transfer. If the belts are too
tight, they may break or wear excessively. The tension of each belt on the fixed and movable rails should be
adjusted evenly. If necessary, adjust the tension as follows:
n
Items to be prepared
• Hex wrench (5mm)
e
1
Press the emergency stop button.
2
Loosen the tension adjusting bolt.
The tension adjusting bolt is located on the right side of the conveyor and linked to the idler on the belt
side. Loosen the bolt (but do not remove it) using hex wrenches (5mm).
3
Adjust the belt tension.
Slide the tension adjusting bolt towards the outer or inner side of the machine to adjust the tension.
