  1. If there are no errors, just perform daily setup and exposure position adjustment from service menu.
  2. Load the backup. It is software problem.
  3. If solenoids works on output check mode means 24 volts is ok. It seems that the problem is mechanical alignment. Try this, remove the dryer rack from the machine and put it on top of a table where you can visually see all mechanical parts. Move the solenoid responsible for the paper that guides going up or down. While moving the solenoid manually, visually check the guide if it is moving perfectly, if not check from there what is the problem, probably it was not in its proper position.
  4. 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.
  5. Please see the attached picture below if it’s original or not.
  6. Optical noise inside laser unit. Probably in Blue channel having caused of this noise.
  7. Original (maybe?) shimadzu purchased from Kanuo China
  8. 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.
  9. Yes for sure. Based on your experience, which more reliable laser head between the two? SHOWA OR SHIMADZU
  10. 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.
  11. Can Anyone tell me the image attached what type of laser unit is in my Qss 3701
  12. Minilab service : I can't able to check those measurements at the moment because it needs to travel by plane. Please anyone who has an original, brand new shimadzu green with driver please send me a quote.
