Topsetter issue

[crashtest]

Hello, I am not new to the forum but first time posting. We are having issues with Heidelberg Topsetter P74 (Screen 4300). We have really tiny lines across the plate. Attached you can see printed image on a paper. The problem exist even on internal tests of the CTP. I will be glad if anyone had a similar issue and could give me some clues, where to search for problem.

Thanks in advanced!

Did you work correctly with these plates until now ? Did the problem appear suddenly ? Is it permanent or coming and going ?

Laser. How long since last service?
Probably dirty lense.
YMMV.
