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. B o b b i n  t h r e a d  r e m a i n i n g 

amount detecting device is 

not used.

Causes

1) Sewing is performed while the de-

tecting 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 re-

maining amount detection.

3) Wipe out the dirt of the reflecting 

plane.

4) Check that all cords or the like have 

been installed. Refer to “

@

. SET-UP”.

5) Adjust the position of the air nozzle. 

Refer to “

#

. ADJUSTING THE SEN-

SITIVITY”.

6) Adjust the sensitivity of the sensor 

amplifier. Refer to “

#

. ADJUSTING 

THE SENSITIVITY”.

1) Adjust the sensitivity of the sensor 

amplifier. Refer to “

#

. ADJUSTING 

THE SENSITIVITY”.

1) Do not use the bobbin for bobbin 

thread remaining amount detection.
