Ls600 scanning problem

Recommended Posts

Hi, everyone 

I bought a Second hand LS-600 recently. Everything was fine when I use it for the first time. 
But one day after when I scan again, I find that there is strange line patterns on the photo(check out the photo below). It happened on every film.

First I thought it’s cause by dust inside the machine, but I have cleaned everywhere I could and nothing change.

Does anyone have the same problem before? And how do you deal with it?

It is some noise during image processing. Might be that noise cause small board on CD, scanner control pcb, connection between them, or noise from power supply. On scanner maintenance interface run self check and look results. Also go to scanner sensitivity check menu and look how works CCD.

hi, sorry for late response. I tried using a isolated power supply, but nothing changed. And it seem that it only happens on highlight area of the film.

 I also ran a self check, nothing wrong. One of my friend suggested me that there might be some problem in LED. He said the light source area is smaller than APS size, but I'm not sure if he is right.

All look good. Do not see noise on sensitivity check menu. Just Green led has a little non uniformity. Self diagnostic didn't find any errors. Maybe here is software bug, partially faulty scanner control pcb, or something wrong with scanner data.

Try upgrade software on scanner board ( from service menu ) . Also make scanner backup and try temporarily load other scanner backup. You can't use other backup - it is only to test. After that have return original settings ( using your scanner backup ) .

Scanner control pcb can test on other scanner. There need to run software update and load other scanner backup. Also can use other scanner board on your scanner. Before removing you need to make backup, which you need load back when return board.

The scanner comes with a backup data disc, I haven't used it yet because I don't know what it is. Should I in stall it?

Common problem, but I don't have a real solution.

Probably negative that is too dense or Positive that is underexposed. 

Try light source calibration and carrier (transport) calibration in EZ (if available - don't have LS600). Check the manuals.
Also try setting scan quality from Standard to High Quality (or vice versa) and different resolutions. Should be less visible at higher res. 

Also check quality of rubber wheels.
