Not entirely familiar with this specific machine, but best guess would be either not in red/rest zone on degree wheel or head is stuck between needle change. Manually adjust and then try turning back on.

Hi,

I,ll try to adjust head position (how to...?)
Not sure to understand your 1st advice, sorry

Thks for your help

Should be a manual way to rotate the needle change mechanism to get it to another needle. If head isn't centered above throat plate, may give you needle position error. Some machines have a light beam sensor to know it is moving needles, some use a magnet and sensor. Need to make sure head is properly aligned.

Hi,
Still having the problem, same message ...

I first think it was about one of the 6 needles position, but (as far as I understand ...) it's not related.
Seems there is no sensor, except the needle number switch, to detect the "horizontal" needle position.

So, I guess it is the "vertical" needle position, but I can't find the sensor, and not check nothing ...

@ElitePromo : the machine is old (1980 ... or so), no light or magnetic sensor for the needle(s). Or I can't find it.
I found only a tachymeter on the main axle.

Is someone has a "service manual" or "maintenance manual" .... i would like to get it !
All advices welcome

thanks for your help

Go to DataStitch.com. They have sold and serviced Toyota machines for decades. They have techs that work on older machines. This is a rock solid company. I used their software for years. I think they would be your best bet.
