Scoring depth adjustment
To adjust the scoring depth, loosen the
knob on the right and left scoring depth
adjustments and turn each axis to the right.
When the axes are in the upright position,
no scoring will be applied.
Depending on the condition, you may need
to adjust only one axis. Turn the axis little
by little by checking the scoring condition.
● If the axis positions on both sides
are very different from each other, a
cover may be torn or skewed.
● If the thickness is less than 3 mm,
move the axes of the scoring depth
adjustments in the upright position
because a score cannot be applied to
that thickness.
