MALACAL Posted October 22, 2010 Report Share Posted October 22, 2010 hi I have an error 340 with SOS frontier, many would say it is an AOM or laser is damaged. but I had the opportunity to try on another machine and the laser, AOM, LDA PCB, PCB LDD, GMB and all is well, any suggestions?

Guest Posted October 23, 2010 Report Share Posted October 23, 2010 some time it is connection or wire broken. but most of the time it is AOM. Did you try AOM from another working machine on your own Machine to confirm? Quote Link to comment Share on other sites More sharing options...
MALACAL Posted October 23, 2010 Author Report Share Posted October 23, 2010 I have a spare AOM install it to your computer, but the error continues Quote Link to comment Share on other sites More sharing options...
MALACAL Posted October 23, 2010 Author Report Share Posted October 23, 2010 diagnostic mode for the printer tells me that there is no connection between the LDA and the GMB but I tested these cards in another machine and work well Quote Link to comment Share on other sites More sharing options...
sisir Posted November 14, 2010 Report Share Posted November 14, 2010 You should check if the RED Lasre is emitting. Quote Link to comment Share on other sites More sharing options...
MALACAL Posted November 14, 2010 Author Report Share Posted November 14, 2010 yes, the red laser is emitting Quote Link to comment Share on other sites More sharing options...
sisir Posted November 15, 2010 Report Share Posted November 15, 2010 Then you should clean all the mirros of the Laser Unit carefully. I think some mirrors are dirty. Especially clean the smallest mirror. Quote Link to comment Share on other sites More sharing options...
yustas Posted November 16, 2010 Report Share Posted November 16, 2010 @malacal Please read here: www.minilablaser.com/errors.htm at the end of the page you will see the right solution @sisir, Why do you always recommend to clean the mirrors?! In each topic where people write about the SOS error - you advise it. As I wrote recently, if the end user will damage the mirror, who will pay for it? you? I doubt... It is impossible to buy the spare parts for laser unit. So from where he will get it? PLEASE NOTE ALL OWNERS of MINILABS with laser engines: Mirrors in the laser unit is EXTREMELY easy to damage! If there is no signal of synchronization - it means that there is no beam at all... Not a weak signal (you mean).. Advising to open the cover you give people a bad advice.

PRASANNA PHOTO TEC Posted November 16, 2010 Report Share Posted November 16, 2010 hi i am seen your problam try slove long days, i am sure Sisir is correct, but you must do very carefully , more peoples dameges mirrors by a clening , any way i have this type mirrors ,i also send out your mail box some advice, please check it and reply me Quote Link to comment Share on other sites More sharing options...
Kevbo37 Posted November 16, 2010 Report Share Posted November 16, 2010 Yustas is correct! cleaning the mirrors is only going to solve a line in the prints or a fuzzy prints or some other image related problem. The sos error is never caused by a dirty mirror. The mirror would have to be extremely dirty which cannot happen inside the unit. It is more likely a bad AOM driver or cable or sensor or even a bad laser. Quote Link to comment Share on other sites More sharing options...
sisir Posted November 17, 2010 Report Share Posted November 17, 2010 @minilablaser I agreed with you that the mirrors in the Laser Unit easy to damage, but you are wellknown that the SOS detection system uses all the Mirrors in laser unit. I found most of the cases of SOS coming from dirty mirrors. As the 370 model is an older model and many users does not clean their mirrors in laser unit, the message can occure. Especially I found most of the cases are occuring from dirty mirrors. You can repair faulty Laser unit, how will you cost for it? 4000$~5000$, am I right? I replaced a faulty Laser Unit in which the polygon motor damages and another mirror was fully broken, with only 4000$ from Singapore. So, what should the user do? If he can get solution by cleaning the mirrors, they dont need to invest about 4000$. But for SOS error they should invest 4000$, also for broken mirror, the same. So, please suggest with financial factor also. @Kevbo37, Dear sir would you explain how SOS is detected in the Laser Unit? Do you know it? I am sure, you dont know the process of SOS detection. But bad AOM causes sometimes, not everytime. Quote Link to comment Share on other sites More sharing options...
sisir Posted November 17, 2010 Report Share Posted November 17, 2010 If the Red Laser emitting it can cause for faulty mirrors, polygon error or Bad AOM or AOM drive. Quote Link to comment Share on other sites More sharing options...
MALACAL Posted November 17, 2010 Author Report Share Posted November 17, 2010 thanks for your suggestions I want to clarify that I have two laser units, both give me the same error and tried it on another sewing machine and working perfectly Quote Link to comment Share on other sites More sharing options...

In this case he will have to obtain another unit and all financial saves go to zero. @malacal Please explain one more time for stupids... You place two laser unit with SOS error to another lab and you have no errors at all???? Quote Link to comment Share on other sites More sharing options...
sisir Posted November 18, 2010 Report Share Posted November 18, 2010 @malacal You have find tow laser unit with SOS error at your machine, but it is OK to another machine, so, it is clear that, your Laser Unit is OK. You should check AOM Drive, LDD20 PCB etc to another machine. Quote Link to comment Share on other sites More sharing options...
sisir Posted November 18, 2010 Report Share Posted November 18, 2010 @minilablaser Thank you for your suggestion. Quote Link to comment Share on other sites More sharing options...
Kevbo37 Posted November 18, 2010 Report Share Posted November 18, 2010 Sisir, The SOS (start of scan) signal is detected by a small photo sensor which receives the reflected beam near one edge (the leading edge) as the beam starts each scan across the paper. For the signal to not be detected the beam would have to be non-existent. If the mirrors were so dirty as to stop any reflection of the beam, it would have caused other problems long before that point. Most notably the operator would never be able to get a good condition print and would have to replace the laser unit before the sos error occurred.

yustas Posted November 19, 2010 Report Share Posted November 19, 2010 @malacal as you can see that your units works well on another lab- there is no need to interfere into laser's internal space (especially clean mirrors) Dig around laser's periphery...

MALACAL Posted November 19, 2010 Author Report Share Posted November 19, 2010 I mount the laser on another different machine and it worked well LDD PCBs, LDA, GMB, and the AOM also another machine shall be installed and worked perfectly Quote Link to comment Share on other sites More sharing options...
