Note
● If the surface of the folding roller is slippery due to dirt or deterioration, the bearing
support lever will not work effectively. Replace the folding roller.
● Do not loosen the fixing screws of the bearing support lever except when you replace it
with a new one.
2.3.2 Adjusting the clearance between the bearing support and
bearing support lever
If the clearance between the bearing support and bearing support lever is wider either on the
left or right, the pressure will be ill-balanced on the left and right and folding misalignment
may frequently occur along the sides of the paper.
1) Loosen the fixing screw on either side.
2) To prevent the brackets R and L from touching the bearing supports, tighten the screws at
the top of the long hole.
