Field Remedy
When the symptom occurs, prepare two sets of the level tensioner unit (FM4-4730) which is assembled, as
a new part, in a direction in which less load is applied to the tension spring. Replace the tension spring and
the gripper open/close lever with the level tensioner unit. [A] shows a tension spring which is assembled in a
direction in which a large load is applied to the tension spring, while [B] shows a tension spring assembled in
a direction in which less load is applied.
1) Remove the dispose assembly[1] from the finisher main body, and loosen the two screws[3] in the gripper
arm assembly[2]. There is no need to remove the screws.
