yustas Posted April 26, 2021 Report Share Posted April 26, 2021 Hi, You have H the first letter. According to Noritsu guide it shows the G laser driver type: • H: G laser driver (J391231) • I: G laser driver (J391160) You have H. So your laser unit now is B1.

H because the installed driver and the laser is J391231. but as I said again and again, the previous laser head and factory installed green laser is Shimadzu with J391160 driver and for sure the letter I will display in system version check.

yustas Posted April 26, 2021 Report Share Posted April 26, 2021 If you would install now J391160 back with a Shimadzu HK9356 laser module- you would see a changed laser type. Quote Link to comment Share on other sites More sharing options...

Yes for sure. Based on your experience, which more reliable laser head between the two? SHOWA OR SHIMADZU Quote Link to comment Share on other sites More sharing options...
yustas Posted April 26, 2021 Report Share Posted April 26, 2021 They have similar reliability, but Shimadzu has better performance. Just remember that both of these laser modules are DPSS modules. They have a rather complex design and a little moody. Quote Link to comment Share on other sites More sharing options...

Tomas Posted May 8, 2021 Author Report Share Posted May 8, 2021 I want to update you regarding this issue! Replaced yesterday the Green laser head from Showa to Shimadzu with the original driver from Noritsu J391160 and Synchronous sensor error disappear. Printer is back to life. Once again thanks for the help. Till the next topic. Quote Link to comment Share on other sites More sharing options...
Minilab service Posted May 8, 2021 Report Share Posted May 8, 2021 Here not full update. What you replaced - fake Showa head, or original? Instead it used original J391160 laser driver with original Shimadzu head, or head made in China? Quote Link to comment Share on other sites More sharing options...
Tomas Posted May 8, 2021 Author Report Share Posted May 8, 2021 Original (maybe?) shimadzu purchased from Kanuo China Quote Link to comment Share on other sites More sharing options...
yustas Posted May 8, 2021 Report Share Posted May 8, 2021 Same fake. Quote Link to comment Share on other sites More sharing options...
yustas Posted May 8, 2021 Report Share Posted May 8, 2021 Shimadzu discontinued a production of the laser modules for minilabs in Nov.2020. This information I received from Japan from Shimadzu guy. And they do not have any plans to begin it. So the desire of your client to step on a rake is simply inexplicable. Quote Link to comment Share on other sites More sharing options...

Minilab service Posted May 9, 2021 Report Share Posted May 9, 2021 Head looks like original. Just one difference - on new and original HK-9356-02 on QSS37 have green top label. Old head was not original? Voltage on resistor really was 7.3 mV ( current 73 mA ) ? Quote Link to comment Share on other sites More sharing options...
Dave S Posted May 9, 2021 Report Share Posted May 9, 2021 Yes measuring the voltage on the resistor will tell us if it is an original DPSS head or not. Taking the top cover off the laser head will also tell us what is what! Quote Link to comment Share on other sites More sharing options...
kodak_service Posted May 10, 2021 Report Share Posted May 10, 2021 (edited) This is a non-original head or a refurbished one. The serial number on the transverse sticker does not match the number on the main sticker. There is no transverse sticker on the original heads. Also, the sticker on the connector must contain a barcode for the original head. Edited May 10, 2021 by kodak_service Quote Link to comment Share on other sites More sharing options...
yustas Posted May 10, 2021 Report Share Posted May 10, 2021 (edited) Yes, I also think so. It is seems it is not an original one because: - the original Shimadzu heads have smaller fixing bolts on the top. - the brand new modules from Shimadzu have NO stickers with a bar code on the top. This sticker is supposed to be added by the person who assembled it into the laser unit. - the brand new modules from Shimadzu have an Inspection and test result document where you can see all release tests data. Here is the top view for the Shimadzu blue laser module HK9356-01. Just compare. https://yadi.sk/i/2S6ZMTsYSeSdkw As a resume: it is a very well-made replica.

Tomas Posted May 10, 2021 Author Report Share Posted May 10, 2021 Probably not original but it doesn't matter now because the problem was solved by changing the laser module. $1K is much cheaper than refurbished laser unit. If this gun will going to lasts for 2 years then it is more than enough. The customer is making a lot of money for this machine. $1K of Gun every year is nothing. No need to argue if it is original or not because for sure it is not because it came from China. Thanks again for your useful information. I am learning so much from this forum.

davidlam Posted May 11, 2021 Report Share Posted May 11, 2021 1) from photo I saw a tiny [ s/n label ] on the SHMADZU silver label . . . that mean they make many s/n G214031 lasers . . . 2) from experience ... copy china lasers are lighter in weight when compared with laser originals.
