Cause
While the finisher is in operation, the gripper arm assembly[2] inside the dispose assembly[1] picks up the
stack of delivered sheets and carries them. At this time, depending on the direction in which the tension
spring[3] of the gripper arm assembly[2] is installed, the tension spring[3] may break due to its endurance.
Accordingly, the stack of paper cannot be picked reliably.
