frontier375 Posted October 17, 2010 Report Share Posted October 17, 2010 Hello im from Bulgariq, excuse me for bad English, yesterday the machine stopped. Error massage Е-2529 SOS Detectin failed. Status display-warming, but all chemical tanks are Off status (temperature is OK) but the icon in the lower left corner of the screen shows status warming. Тemperature of the laser is only 25 degrees and no heat. I have another Frontier 370 her temperature is 27.5 degrees. Where is the problem and what needs to be replaced? Thanks for attention.

Christina Rose Posted October 18, 2010 Report Share Posted October 18, 2010 SOS detection error related with many parts. probably due to bad AOM, LDD22 PCB and worse come Optical unit ( Laser). Quote Link to comment Share on other sites More sharing options...
yustas Posted October 18, 2010 Report Share Posted October 18, 2010 Hello, Error 2529 -> "SOS detection failed" means that your minilab cannot get the "Signal of Synchronization" from the RED laser ( this gun is the only source of synchronization). Causes: AOM driver, AOM (crystal), poor connection between : 1. AOM driver and IMAGE PROCESSOR PCB 2. AOM-driver and AOM (crystal) First you need to do: swap RED AOM driver with to GREEN AOM driver. if you do not want to remove drivers and place them back- just change cables and see the result: NOTE: you need to cross cables from the top and bottom! Some customer just change only top cables and forget to change the bottom ones. So do not forget. See pictures (sorry for ugly drawings) If you have no error 2529 and at same time you have no magenta color- it means AOM driver is dead. If you have no changes - it means AOM (crystal) is dead. In anyway you cannot repair AOM or Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 18, 2010 Author Report Share Posted October 18, 2010 Thank you very much friends, we'll check everything you say and write will result in a few days. yustas whаt is - AOM crystal??? of which says so? Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 18, 2010 Author Report Share Posted October 18, 2010 ....what you mean is AOM crystal? Quote Link to comment Share on other sites More sharing options...
ghn5ue Posted October 18, 2010 Report Share Posted October 18, 2010 What we usually refer to as an AOM is actually an AOM driver. The actual AOM is a crystal or piezo element within the laser unit (optical section). The AOM driver sends a signal to the piezo element, causing it to resonate. Yustas can correct me here if I am wrong, but I believe this resonating modulates the light coming from the laser to change it's intensity and color.

frontier375 Posted October 18, 2010 Author Report Share Posted October 18, 2010 Тhanks friend, I understand perfectly Quote Link to comment Share on other sites More sharing options...
yustas Posted October 18, 2010 Report Share Posted October 18, 2010 Hi, "ghn5ue" is right. AOM always mix with AOM driver. But I never mix it and write correctly. If you find out that AOM is dead - no need to interfere to the laser internal section (open the cover) - there is nothing inside to repiar by end-user. Moreover if you have almost same lab - you can easily to localize the problem. Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 19, 2010 Author Report Share Posted October 19, 2010 Bad news, I changed cables AOM green, do not fix the problem. I changed all red AOM-driver, does not fix the problem. We have a Frontier 370. Yustas can I change from Lazar Unit Frontier 370 of 375, have got some sort of difference. I will find a problem in laser or is it in the motherboard.

yustas Posted October 19, 2010 Report Share Posted October 19, 2010 It is difficult for me to say if the Frontier's 375 laser unit differs from 370 laser or not... We repaired only 350/370/390 laser yet. They are more often are subject for repair. Fr 375 is newer and we have never had complaints for laser problems. So we have now it from you. Cause we never met with 375 so far so you will have to compare them (laser units) by yourself. Also I hope there is a lot of visitors on the forum who can advise you how to compare them. P.S.

Christina Rose Posted October 19, 2010 Report Share Posted October 19, 2010 In frontier 375 printer section LP2000 same as frontier 370 printer. LP 1500 with SP3000 called frontier 355 annd LP 2000 with SP3000 refereed as frontier 375. so optical part is common for all 350/370/355/375.

frontier375 Posted October 20, 2010 Author Report Share Posted October 20, 2010 Very good news, I changed the laser of 375 to 370, the laser works. Then I changed the motherboard LDD20 and it worked. Tomorrow I go to change parts until I find who is guilty. Most important is that the laser is alive. Quote Link to comment Share on other sites More sharing options...

sisir Posted October 21, 2010 Report Share Posted October 21, 2010 I think it is from Laser Unit. You can solve it by cleaning all the mirrors carefully inside the laser unit. I faced such types of problems several times in Bangladesh. Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 22, 2010 Author Report Share Posted October 22, 2010 Thank you friend, will check that. All parts are changed with 370 work. AOM, all motherboards, power supply, cables, everything works, even machine (375) yesterday work, copy the photos over 300pieces and this morning a few copies still E2529 stopped again and again. What do I do not know. We can not discover what makes this problem when he wants. Quote Link to comment Share on other sites More sharing options...
sisir Posted October 24, 2010 Report Share Posted October 24, 2010 Just Clean all ther mirrors (Large and small ones also) and I think your machine will work well. Quote Link to comment Share on other sites More sharing options...
yustas Posted October 25, 2010 Report Share Posted October 25, 2010 Mirrors are not the cause of your problem... And if you decide to clean it - you will loose them. If you spoil mirrors- you will kill the laser unit. It is impossible to buy them separately. But in your case- you have dead AOM crystal. P.S. If you decide to clean mirrors - we will tell you how to clean them (if you really will need it) Quote Link to comment Share on other sites More sharing options...

sisir Posted October 26, 2010 Report Share Posted October 26, 2010 As sometimes it is printing, I dont think about dead crystal. If the crystal is damaged or dead the machine will never prints. Quote Link to comment Share on other sites More sharing options...
yustas Posted October 27, 2010 Report Share Posted October 27, 2010 Dear Sisir, You a bit wrong here. Minilab can produce prints even if a crystal is dead. Not always but time to time it will print. Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 27, 2010 Author Report Share Posted October 27, 2010 Тomorrow will come technician, we are powerless, we will see you will discover why. Тhank you Yustas, thank you Sisir, i will tell what the problem with FR375 tomorrow. wish me luck. :o Quote Link to comment Share on other sites More sharing options...
frontier375 Posted October 29, 2010 Author Report Share Posted October 29, 2010 laser modulator is dead. We changed the laser unit with laser unit FR390, the machine now works. But we should seek modulator. yustas where we can find a modulator? you sell it? And what is your price? Quote Link to comment Share on other sites More sharing options...
Kevbo37 Posted October 29, 2010 Report Share Posted October 29, 2010 I doubt that the modulator is actually dead. I have never seen a bad modulator in about 1000 units I have repaired . They can get contaminated or become misaligned, but can always be restored to service. PM me if you want more info on how to get your unit repaired.
