yustas Posted November 1 Report Share Posted November 1 The described problem (if to look at the second photo) is highly likely a problem with the noise of a green laser module. Quote Link to comment Share on other sites More sharing options...

Minilab service Posted November 3 Report Share Posted November 3 Why to write what do not understand? First wrote to change bearings. After that wrote to change AOM driver. Here absolutely different things and all that will not help. On minilab is magenta noise caused by Green laser head. It is typical fault on older QSS37 models ( except models with G ) .

I am happy to help people on here who ask for advice. Giving someone wrong or false information helps no one, it's just a waste of everybody's time. People need to know the limits of their knowledge. If they don't fully understand something, it's better for them not to post at all rather than post nonsense. Quote Link to comment Share on other sites More sharing options...

He likes to write something what he doesn't understand. Many times saw it. He wrote two advices and both absolutely useless. You can be sure - if to change bearings, change AOM driver still have noise, which is caused by Green laser head. Quote Link to comment Share on other sites More sharing options...
Bayazed Posted Tuesday at 12:10 PM Author Report Share Posted Tuesday at 12:10 PM i replaced the AOM but still same i think the issue its from laser control PCB board for qss37 because not showing any error code of green laser also becouse when i checked on the system its show no error of any laser and i do synchronization for lasers , the green laser is slow synchrous not as fast as other lasers i do not know which i have to change first green laser or laser control board PCB !!!

kodak_service Posted Tuesday at 12:21 PM Report Share Posted Tuesday at 12:21 PM It has already been said several times that the green gun needs to be replaced and repaired. Why ask meaningless questions? “We must look where we lost it, and not where it is light.” Quote Link to comment Share on other sites More sharing options...
yustas Posted Tuesday at 02:41 PM Report Share Posted Tuesday at 02:41 PM Right after seeing your pictures, I posted that you had a problem with the green module. That was over a month ago. You have wasted a whole month. I have seen hundreds of these photos and I know what I am writing here - your green laser is dead. Replace it.

Sometimes even there’s no error doesn’t mean that the green laser is good. From your sample print I can see magenta noise. All the experts from this forums said green laser module needs to replace. No wasting time just replace it. Quote Link to comment Share on other sites More sharing options...
