      If there are no blend indication(s) or damaged area(s) on a stage, this SUBTASK does not need to be done on that stage.
      To do this SUBTASK the drum must be orientated in the vertical position with the retaining slot uppermost. The orientation will vary depending on the stage affected.

      2. NOTE

        If the depth of dressing at AE on stage 3 is larger than 0.079 in. (2.00 mm), then a long retaining plate must be installed over the damage.
