The led bar doesn’t work…
我如何检查领导,wirin吗g,… ?

i follow :How to turn light on while printing?
But nothing to do…

提前感谢的。

Are you saying it never lights up, or just doesn’t stay on during printing even following that trick?

I say it never lights up !

Where did you buy it? I would get more information there, because maybe it’s broke or something is missing, that happened to me one time.

I think the light is broken… did you repair it ?
