[Precautions to be taken in setting]
It is recommended to place the material at the location that is 65 ± 5 mm from the center of needle as far
as possible.
In the case you want to set the amount of feed from the material edge to the first buttonhole to 60 mm or
less, in particular, place the material in the range of 60 and 65 mm from the center of needle.
Sewing cannot be carried out unless the material is placed near the notch in the preset table (52 mm
away from the center of needle).
60 mm or less
Example) In the case the amount of feed from the material edge to the first buttonhole is set at 50 mm and
the material is placed at the location 75 mm away from the center of needle
After the material is delivered from the preset table to the carriage, the material edge is detected by the
carriage: The carriage moves to the left by 10 mm (75 - 65).
To sew the first buttonhole: The carriage moves to the left by 15 mm (65 - 50).
In all, the carriage has to move to the left by 25 mm. However, the amount of travel of the carriage is
limited to 20 mm at the maximum. As a result, an error occurs in the aforementioned case.
52 mm
55 to 65 mm
In the case the edge width (normally approximately
7 mm) is smaller, the sensor may not detect the ma-
terial edge. In this case, adjust the position of the
sensor to such a position (toward the operator) that
it is able to detect the edge.
