Unfortunately not, if the emitter has gone dim it will have to be replaced. It only needs one bad emitter to effect the whole fibre optic network.

This problem is often down to weak output from the fibre optic emitters. Compare the brightness of the fibre optic ports (ports with the white ring) any that look dim will likely be the causing the issue.

The Laser alignment settings look OK. The confirmation print is too small for me to see it clearly enough to completely confirm everything is correct. Can you show me the value for each step on the daily setup print. I need the readings from step 1 to step 22. A screen shot of the correction screen is good enough

Send a screenshot of the Exposure Position Adjustment page so I can see the values you have set.

I have asked you to upload a scan of the Exposure Position Adjustment test print 2-3 times now, until you do this I cannot give you any further help. Sending more and more prints of the same problem is not useful in helping to identify the problem. So I will ask you one more time. Make a 600dpi scan of the Exposure Position Test print together with the values you have in the settings, and upload the link here. Do the same with the Exposure Position Test Print Confirmation print.

Windows Start, All Programs, LS-600

Enter the service mode: Go to Menu → Extension → Maintenance → Various Adjustment → Printer Mechanical Adjustment → Exposure Position Adjustment F-Functions Test Print Choose the image that the Magenta and Cyan line up perfectly for example 1E, enter this number into the settings Now do the same for the Yellow and Cyan. Do the same for section D1 and D2 After you have done this, F-Functions Test Print Confirmation Confirm the 0 lines (indicated by the arrow) are all be perfectly in line now.

As Minilab service has said, the Exposure Position Adjustment has not been done correctly. When you print the confirmation print the 0 lines (indicated by the arrow) should all be perfectly in line.

That's a nice box to have!

The SSR's are 2A not 3A on the V30/V50. The V50 uses a 400W heater for the CD and STB so the circuit board will handle a 400W heater, but the V50 has a cooling fan fitted where as the V30 does not, so there is a risk of the circuit board getting too hot with the extra load of a 400W heater on the V30. So it is not something I would recommend you do.

Make a scan of the Exposure Position Adjustment confirmation print in high resolution so we can see if it is good or not.

It's impossible to see the details on the photos you have attached as the resolution of the pictures is too small to zoom in. Scan in the photos at 600dpi then I can see the issue and advise you better.

Which machine model? Your images are too small to see what the issue is, upload a high resolution scan to WeTransfer etc and share the link on here.

Does the LS-600 maintenance program see the scanner?
