V2.13.0 finds network scanner epson GT-20000 but scan button is inactive

It works again after removing gscan2pdfrc in hidden user directory .config

Apologies for the delay in responding. December never has enough hours in it.

I suspect the problem is that the epkowa backend embeds the IP address in the device name, and if it picks up a new IP address, then it won't find the scanner.

The workaround would probably be to scan for devices from the device dropdown on the scan dialogue.

Please try the above next time you have the problem. If it works, then I'll add a check for an IP address in the device name and suggest the new scan to the user.

Yes, my Epson GT-20000 is indeed connected via network BUT I configured my dhcp-server to always give this specific IP address to the scanner, so it does not change between sessions!

Looks like this problem is related to a manual setting of the scan top-left or bottom-right value!

As long as I choose the paper size from the Scan area drop-down, it automatically adjusts the right-bottom x and y values and everything works as expected.

But as soon as I manually enter any right-bottom x or y value it will use this setting for the next scans, but if I change the Scan area drop down again to a new format, scan2pdf will NOT update the right-bottom x, y values accordingly and saves wrong settings.

Current workaround is closing gscan2pdf, delete gscan2pdfrc in .config and restart again with default settings.

So the bug-title would need to be updated to this specific problem...

The log file you attached has the end missing, I expect because you uploaded before quitting gscan2pdf. Would you mind posting another, having opened gscan2pdf, reproduced the problem, and quit? The file should then have been compressed with .xz.

I attached a new log.xz that documents my settings. I tried different formats after I manually set the y-scan-area value but the value just does not update anymore...

Thanks for the log. I assume the problem is that you end up with multiple conflicting options which gscan2pdf can't satisfy simultaneously - e.g. from the first log you started with:

'scan-area' => 'A4 Landscape'
'br-x' => 210
'br-y' => 297
'quick-format' => 'A4 Portrait'

i.e. in reality, it is impossible to combine scan-area=A4 Landscape, plus quick-format=A4 Portrait, and gscan2pdf has no way of knowing that. Not sure how to fix this.
