Epson DS-310 about pyinsane HOT 15 CLOSED

Hmm, actually, since you have only one source, I can work around this issue easily. If there is just one source, I just have to not select one --> no selection = no error --> no problem :)

Yup, it scans now. But processing the scanned document seemingly takes forever (I have two tesseract processes at 12 minutes of CPU time right now for a single page), when run manually tesseract takes ~1s per page for me so that's definitely unusual. It's also still throwing SaneExceptions, but these don't prevent it from scanning. Diagnostics

(it seems there are other issues with tesseract 4 as well, have you tried out this combination yet? Paperwork sees and indexes every word in the document as b'word'. This is a very separate issue though. I'll continue using my custom scanning/OCR pipeline for now, I guess. See the resulting
paper.1.words )

Anyway, since your scan problem is solved, I'm closing this ticket :)
Feel free to comment here if you still have issues with scanning, and I'll reopen this ticket.

Hello,

Paperwork diagnostic output just show that Sane or your driver returns SANE_STATUS_INVAL. It doesn't tell us anything else.

Can you post a scan report using IronScanner please ? It will include much more detailed informations, including Sane debug output and your driver debug output.

OK, will do when I get home. For the record, the DS-310 is identical to the ES-200 and both are related the DS-360W / ES-300W, which is the same scanner with wifi and a battery.

There you go: https://openpaper.work/en-us/scanner_db/report/120/ - it actually scanned successfully after what ignoring(?) the pyinsane errors :)

Did it use the automatic document feeder as expected ? oO

from pyinsane.

Yup! I didn't put the paper in completely straight so it's a bit crooked but it worked nicely

from pyinsane.

Weird ... I guess I can make it work but .. weird. (and annoying .. the workaround will be ugly)

Flatpak version will include the fix: https://origami.openpaper.work/#/builders/7/builds/67

Can you install the version from git and confirm the workaround works please ?

from pyinsane.

I’ll give it a try as soon as I get a chance. Thanks for the quick response!

from pyinsane.

Thanks for the feedback. I'm using the flatpack version of Paperwork. I will lookout for the next flatpack version and try that.

You're using Tesseract 4.0.0alpha in Paperwork. This version is buggy and randomly slow. I suggest you either update it or switch back to Tesseract 3.05.
