Phenomena

1.  Sensor cannot detect even 

when thread in the bobbin 

has completely run out.

2.  Sensor detects while the 

re

fl

 ecting plane of bobbin is 

not fully exposed.

3. Bobbin 

thread 

remaining 

amount detecting device is 

not used.

Causes

1)  Sewing is performed while the 

detecting switch 

fl

 ashes on and off.

2)  Bobbin for bobbin thread remaining 

amount detection is not used.

3)  Reflecting plane of bobbin for 

bobbin thread remaining amount 

detection is dirty.

4)  Cords or the like are not installed.

5)  Air coming from air nozzle is not 

blowing to the lens of the fiber 

sensor and dirt adheres to the lens.

6)  Sensitivity adjustment value of the 

sensor ampli

fi

 er is not proper.

1)  Sensitivity adjustment value of the 

sensor ampli

fi

 er is not proper.

1)  Sewing process is not the process to 

which the bobbin thread remaining 

amount detecting device is used.

Checking or correctuve measures

1)  Press the detecting switch once to 

go it out.

2)  Use the bobbin for bobbin thread 

remaining amount detection.

3)  Wipe out the dirt of the reflecting 

plane.

4)  Check that all cords or the like have 

been installed. Refer to “II. SET-UP”.

5)   A d j u s t  t h e  p o s i t i o n  o f  t h e  a i r

THE SENSITIVITY”.

6)  Adjust the sensitivity of the sensor 

ampli

fi

 er. Refer to “III. ADJUSTING 

THE SENSITIVITY”.

1)  Adjust the sensitivity of the sensor 

ampli

fi

 er. Refer to “III. ADJUSTING 

THE SENSITIVITY”.

1)  Do not use the bobbin for bobbin 

thread remaining amount detection.
