8) Measure the distance (L) between the stitch-
ing position and the folding position. Then,
perform “positive width adjustment” or
“negative width adjustment” to suit the re-
lationship between the stitching position and
the folding position.
• If the stitching position is below the folding
position, perform “positive width adjust-
ment.”
• If the stitching position is above the folding
position, perform “negative width adjust-
ment.”

9) Change the settings of bits 6 through 8 on
DIPSW1 referring to Table 8-102 below.
• If the width adjustment is “0”,
The stitching position and the folding posi-
tion match, requiring no change.
• If for “positive width adjustment,”
Set DIPSW1 so that the difference result-
ing from subtraction of the interval from the
appropriate setting in Table 8-102 is pro-
vided.
For instance, if the DIPSW1 is currently set
to +2 and the interval is +1 mm, set
DIPSW1 to reflect -2.
• If for “negative width adjustment”
Set DIPSW1 so that the sum resulting from
addition of the interval from the appropri-
ate setting is provided.
For instance, if the DIPSW1 is currently set
to -1 and the interval is +0.5 mm, set
DIPSW1 to r1.
