airsane can't scan while scanimage works #82

Closed ilya-fedin closed 2 years ago

ilya-fedin commented 2 years ago

I have a weird issue that airsane detects the scanner, but can't scan (tried with mopria & web interface, both failing) while scanimage started as the same user works just fine.

Here's the log running in normal mode:

SimulPiscator commented 2 years ago

The [compression] = "JPEG" setting might be a problem. Try compression=None in /etc/airsane/options.conf.

ilya-fedin commented 2 years ago

Looks like airsane doesn't understand that line, I'm still getting [compression] = "JPEG" in debug mode

ilya-fedin commented 2 years ago

Oh, it's because there's a device genesys:.* line and I added the line to the end of the file.

So, the error in normal mode is still the same:

окт 16 00:37:32 rpi4 airsaned[25408]: io/hpmud/pml.c 374: SetPml channel_write failed ret=31

And I don't see any difference except of compression in debug mode:

Interesting, looks like airsane sets source to ADF forecfully and I'm not able to override that even with options.conf. scanimage says that the regular default is Auto:

    --source Auto|ADF [Auto]
        Selects the scan source (such as a document-feeder).
ilya-fedin commented 2 years ago

Apparently, that's the reason for fail since I put the sheet into the platen and the feeder is empty

ilya-fedin commented 2 years ago

изображение :thinking:

ilya-fedin commented 2 years ago

I applied such a patch:

And scanning started to work!

SimulPiscator commented 2 years ago

Cool, thank you! But doesn't "Auto" mean "use flatbed if no paper is in ADF"?

ilya-fedin commented 2 years ago

But doesn't "Auto" mean "use flatbed if no paper is in ADF"?

Most likely, yeah. I don't know whether there's any equivalent of 'Auto' in AirScan protocol, so I just made a fast hack to check whether my assumption is right or not :)

SimulPiscator commented 2 years ago

No, there is no equivalent of "Auto" in the AirScan protocol. I don't know how to handle this case.

ilya-fedin commented 2 years ago

I guess 'Auto' can mean only two things in practice:

  1. It's a scanner without a feeder, so it means platen definitely
  2. It's a scanner with a feeder and it will try to scan via feeder and fallback to the platen, so it's a good idea to have it as a fallback for platen scan type when there's no options like 'Flatbed'
SimulPiscator commented 2 years ago

I think you are right, I'll take your patch.
