Eventually, the same problem occurred to me

I used Google translator.

I saw the problem to others here in the community.
I was thinking the laser problem is very serious.
And wished that you do have that problem happen to me.
But a few days ago … I experienced the first failure.
It was found that it is a laser problem.

Is not it?

I think that these problem is defect.
Because It caused to so many people having the same problem.
I was very disappointed to you(formlab).
Anyway I need to fix my printer. How do I?

Open a support ticket and be sure to attach that last picture for sure. They will replace your printer. There is really nothing you can do on your own unfortunately. The good news is the replacement will probably be upgraded to a Form1+.
