FUJITSU fi-6130dj Duplex scan

[kern...@gmail.com]

Hello,

I have tried scan a duplex Page with jfreesane an a FUJITSU fi-6130dj.

The code I used:
open device ...

RenderedImage image;
SaneOption option;

option = device.getOption("source");
option.setStringValue("ADF Duplex");
while (true) {
  try {
    n++;
    image = device.acquireImage();
    saveImage(image, n);
  } catch (SaneException e) {
    if (e.getStatus() == SaneStatus.STATUS_NO_DOCS) {
      // this is the out of paper condition that we expect
      System.out.println("No more pages");
      break;
    } else {
      // some other exception that was not expected
      throw e;
    }
  } catch (IOException e) {
    e.printStackTrace();
  } catch(IllegalStateException e) {
    System.out.println(e);
  }
}

I can not get the back of the page, just the front.

If I tried to scan the front with "ADF Front" or the back with "ADF Back" it works just fine.

If I use the sane-tool scanimage both sides of the pages get scanned.
scanimage -d fujitsu:fi-6130dj:201348 --format=tiff --batch=tiff%d.tif --source="ADF Duplex"

Thanks

Hey Armin,

Thanks for the report. Are you able to use tcpdump to capture the
interaction between scanimage and SANE? I think you'd just need to
replace the -d line with net:localhost:fujitsu or something similar to
ensure that scanimage is using the SANE daemon. If you could send me
the tcp dump that'd greatly help in debugging.

Regards,
James

Hello James,

I scanned 3 double sited pages.
scanimage -d net:localhost:fujitsu:fi-6130dj:201348 --format=tiff --batch=tiff%d.tif --source="ADF Duplex" --resolution=100 --y-resolution=100

I captured the network traffic with:
tcpdump -i lo -w lo
see attachment.

I tested the file with wireshark it is OK.

Thanks

Awesome, thank you. I wrote a wireshark dissector for sane and
hopefully it will help figure out what SANE is doing and why jfreesane
doesn't work. Will get back to you soon.

[James Ring]

Can you also capture the interaction between jfreesane and sane using tcpdump?

I just tried ADF Duplex scanning with my Canon Pixma MX7600 and it
worked OK. Can you also make sure you're using the latest jfreesane
from github?

Thanks,
James

Hello,

I have the same problem.
Have you found a solution?

Thank you.

Hey Diogo,

Are you able to build jfreesane from source and try your program with
the following patch:
https://github.com/sjamesr/jfreesane/commit/a2fff376ae46ce38dbc9ec84bbcd71703c1a0556
?

You can check out the "remove_cancel_from_a" branch and this patch
will be present already.

Thanks,
James

That's excellent news, I definitely need to check this in to the mainline.
