Hi harkon,
as you already found out, it has nothing to do with my tool. Looks like the sane driver for your specific scanner is not that good. The Windows drivers are mostly from the vendor and most of them are not delivering drivers for Linux. Before buying any devices, first check the Linux compatibility!
I'm just calling scanimage (the SANE comandline scan tool). I suggest to test using this tool directly. If you're on Ubuntu, you also may try to ask your question in the Ubuntu forums (they are quite good).
I've had similar issues with my fujitsu fi-4120C and solved it by installing more recent sane packages. The idea and help was also from the Ubuntu forum. So, maybe you give it a try?
Best,
Kukulkan
Scan to PDF tool for Linux (only Linux)
Re: Scan to PDF tool for Linux (only Linux)
Thanks again. You are correct, the internet has many posts on the ScanJet3500C and sane. It's still a great too and points me in the right direction.
This scanner was free to me, so I can't complain. I do mostly run Windows in a VB VM along side my Mint host machine so it's not a problem, or at least not a new problem. Thanks again for posting this. I will be using it once I get a better scanner.

Re: Scan to PDF tool for Linux (only Linux)
Update:
If you get error "Error during save. Try again...", please edit /etc/ImageMagick-6/policy.xml and ensure this line (may already be there):
You need root permission to edit this file (or use sudo).
Interestingly, it worked before and I've never had to edit this file before. It suddenly stopped working after some recent update of my Ubuntu 16.04 machine. Some update may have either added the line above with rights="none" or it was ignored before...

Thanks Kukulkin.
When I execute the debug window throws me some errors;
My still be an issue with this silly scanner, but the errors might be something you might want to know about.
*edit*
Just discovered that sometimes if I reopen the program and scan again, when the calculating scan time progress is finished, the last scan image is in the window, and that is the image that then gets saved to PDF. It's like it's one scan behind. Again, may be an issue with this stupid scanner, but I though I'd at least mention it.

Re: Scan to PDF tool for Linux (only Linux)
Hi harkon,
yes, sounds like an issue of either scanimage or the scanner itself. Please note that my program neither deals with the scanner directly nor controls it. It just calls scanimage and let it do the scanning job.
You may use the debugged line to test your scanner manually on the commandline/terminal. From your post, execute this:
Does that work? You should be able to see any error messages here, because my tool does not really deal with errors (except it works or not).
[edit]I just remember that scanimage is having troubles with two sided scans and ADF. This also caused weird results for me. Maybe your scanner does that by default? Use scanimage -A to find possible options of your scanner. You can add them in the field of my tool. I have some Fujitsu scanner where I do --source "ADF Front" to let it use only the front page.
If the scanner is making trouble, I suggest to first try to make it work using commandline (you can take the debug output as a start and call scanimage --help for further options). By this you find the individual driver options and get direct feedback about possible issues.[/edit]

Re: Scan to PDF tool for Linux (only Linux)
Thanks, probably the scanner driver. Either way, I just thought I'd relay the debug errors I was seeing.

Re: Scan to PDF tool for Linux (only Linux)
I just updated this tool to also allow saving password protected PDF files.
Hint:
You may need to install qpdf for this feature to work

Thanks for this @Kukulkan.
I will update my copy.
