Dear all,

In our facility, we have two slide-scanners (Olympus VS120-L100) which
are highly used. Unfortunately, since few days we have been experiencing
a random error.
When working in fluorescence batch mode, the systems stop scanning after
a certain number of slides and the associated error displayed is “Image
is write protected”. We haven’t found anything in the slides to explain
the error.

For an automatic multiple slide scanner this is an issue because it is
disrupting the flow of acquisition and our users are piling up.

Obviously, we are in contact with the service team but I would like to
ask if others on this list have had this kind of problem and, if yes,
what the solution was.

Thank you in advance for your help.

Best,
Luigi

Dear Luigi

That is vaguely reminiscent of a problem I've seen with Matlab writing to TIFF files. Do you have a Windows File Explorer window open to the directory you're writing to? Windows rather unhelpfully tries to preview any files it can find in the directory as soon as they change, and in the process it locks the file. The lock is released very quickly, but if you're writing to the same file repeatedly (as a slide-scanner presumably would) sometimes the lock doesn't get released in time and your software can't write to the file. The solution is to write in a format that Windows doesn't know how to preview (such as a file with an unknown file extension - you can rename it afterwards), or most of the time closing all Explorer windows also works.

I realize that's something of a long shot, but who knows - it might help!

Chris
