① Check the distance between the solenoid pin and the measuring length band

測長バンド=measuring length band,ソレノイドピン=solenoid pin

If the distance is too far

Another volume of thread may come out before the pin reaches the hole in the measuring length band.
The solenoid also cannot eject the pin as soon as the signal comes. There is a slight time lag.

If the distance is too close

If this distance is less than or equal to the thread thickness, friction problems will occur.
