Digital printer Posted October 19 Report Share Posted October 19 Hello everyone, with your support let me post my problem regarding my Fuji 7500. G laser control error popped in after 10min pass from printer On. I tried to check from ouput check but G laser stays at asynchronous and polygon frequencies in zero. I replaced AOM, laser control pcb, and checked 5v and 24v from laser control pcb and laser power supply but still G laser control error. Is there a possibility that my green laser gun or Aom crystal gone? please advise me what to do. Appreciate your help. Quote Link to comment Share on other sites More sharing options...
Minilab service Posted October 19 Report Share Posted October 19 Faulty laser head. It typical on QSS37 ( except on minilab models with G at the end ) Quote Link to comment Share on other sites More sharing options...

Today Fuji Technician replaced the Green laser gun including the driver board ( Chinese version). Thankfully the Green laser control error doesn’t appear again and prints are good enough after exposure position adjustment and daily setup has been made. Thank you for your support and giving accurate information. Quote Link to comment Share on other sites More sharing options...
