10 years ago Thanks for your kind words and the bug report. Please install the v0.0.0.2 debug build and catch the debug logging using DebugView. Please run DebugView with administrative privileges and kernel logging enabled in order to catch the WIA micro driver debug logging. Then post the debug output of such scan failure here, so that I can investigate on the issue. Thanks.

10 years ago Thanks, you may want to try the v0.0.0.4-5-g330f5a1 release build. It won't output any debug data, but it contains changes that may also fix your problem.

10 years ago @fruel Did you also try a new release and see if it fixes your issue?

10 years ago Sorry for not responding so long. Right now I have some problems with my SANE server (no devices found, maybe a permission issue, not wiasane specific) and not much time to fix it (finals weeks in college).
Will try to test it as soon as possible.

9 years ago Again, sorry for not responding so long :) I'm not using my scanner that much.
Today I completely re-installed my server. It is running Ubuntu 14.04 LTS now with the most up to date Sane/HPLIP. On my PC I am running wiasane v0.1.1.9. Scanning works fine up to 600dpi now. 1200dpi is still not available but that's not an issue for me.

9 years ago Thanks for the update. Please check if 1200dpi is actually available to SANE by running winsane-dbg.exe against your server, like this: winsane-dbg.exe <hostname or ip> <port>

9 years ago Looks like it is not supported by SANE or HPLIP. Running "scanimage --resolution 1200 > /dev/null" on the server returns "invalid argrument".

Scan? (y/n)Okay, thanks. :-)
First of all: Amazing project which you started here!
Installation worked flawlessly. Scanner was immediately recognized by all WIA applications.
Scanning with a resolution < 300 DPI works without problems. If I select a resolution >= 300 DPI the scanner starts and finishes the scanning process but at 99%/100% the application aborts with an error message.
Errors:
Environment:
Using "scanimage" directly on the server or "SaneTWAIN" on Windows I can scan up to 600 DPI successfully. (but TWAIN is old and only a few applications support it)
