No print whatsoever

So the printer has been working for a couple years without issue. However, the last couple of prints I find nothing on the platform and nothing in the tank. It almost appears like the laser isnt working at all. Could resin somehow gotten on the mirrors maybe? Any ideas I can try?

It’s possible there might be dust inside the printer, in general it’s much more resistant to getting dust inside compared to the Form1 but it can still happen

You have a Form 2?
You can try this: Empty and clean the vat and then put the printer in open mode. Put a sheet of paper in the vat and start a print without the print platform installed. Then you can check if there is no laser spot at all or if it is weak.

У меня такая же проблема, пожалуйста кто может дать мне совет как проверить работоспособность лазера? Заранее благодарю
