CHAPTER 3 STARTING BINDING OPERATION
8. Using Wing Scoring
When you want to turn-in a cover, use the wing scoring (optional) to apply a score to a position to be
folded. The range you can apply a score is between 120 to 189 mm (4.72 to 7.44 inches) above the
scoring base line on the non-operator's side and between 160 to 199 mm (6.30 to 7.83 inches) below
the scoring base line on the operator's side.
As the wing scorings are located on the operator's side and non-operator's side, first adjust the wing
scoring on the operator's side, then that on the non-operator's side.
