[sane-devel] Canon ImageClass MF269dw

Tue Apr 16 17:57:02 BST 2019

Hi,Hmmm, sounds like a device permissions issue.
This is a little out of my usual area.
A couple of things to check:1) Check /lib/udev/rules.d/60-libsane.rules and make sure there is something in there for your USB device (or whatever file has libsane in the name). I think you need an entry to get permissions as a normal user. https://forums.linuxmint.com/viewtopic.php?t=5945&start=40

2) You could try to run the scanimage as root to check I guess to see if it is a genuine permissions issue.
3) Make sure that you don't have a mixture of package sane and locally installed binaries from your build. I know this does cause problems sometimes.
Cheers,Ralph

 Alas, I cannot report success. I was able to modify and build as you suggested.
  I now get this: $ sane-find-scanner 

   # sane-find-scanner will now attempt to detect your scanner. If the
   # result is different from what you expected, first make sure your
   # scanner is powered up and properly connected to your computer.

   # No SCSI scanners found. If you expected something different, make sure that
   # you have loaded a kernel SCSI driver for your SCSI adapter.

  Any other info that might help? I've attached the patch. Regardless, thanks very much for your help.

 Hi, Good luck! A lot of the imageClass (I-SENSYS in Europe, I think) printers seem to be pretty much the same inside with slight software variations.
  Seems like they keep having to churn the designs externally.  
  Cheers, Ralph

   Thanks for the quick response, Ralph, I'll take a swing at building it and post the results to the list.

      Hi, It is an imageClass printer by the looks of it. The USB code does not seem to be listed in the source so probably not a supported printer. The relevant code is in the SANE backends here: 
  https://gitlab.com/sane-project/backends/blob/master/backend/pixma_imageclass.c

  See the list of #defines at the top. If you're feeling adventurous, you could add the printer to the source and see if it works. It looks very similar to the MF244 so you could use that as a template.

  At the top, add: 
  #define MF269_PID  0x27f4 

  and towards the bottom, add: DEV ("Canon i-SENSYS MF269 Series", "MF269", MF269_PID, 600, 300, 634, 1050, PIXMA_CAP_ADF),               /* max. w = 215mm, */

   ...and build it and test it. Better to start with USB rather than network.

  Failing that, perhaps Rolf could add it tentatively for his PPA. He is usually pretty responsive. 
  Cheers, Ralph

 I was able to use a Canon ImageClass MF260-series with vanilla Ubuntu 
  18.04 recently, I'm pretty sure it was the MF264dw.

  I ordered one for myself, but failed to notice that I was getting the 
  MF269dw instead of the 264.

  SANE-powered apps don't seem to be able to detect the scanner, though 
  the printer works fine.

  $ sudo sane-find-scanner

     # sane-find-scanner will now attempt to detect your scanner. If the
     # result is different from what you expected, first make sure your
     # scanner is powered up and properly connected to your computer.

     # No SCSI scanners found. If you expected something different, make 
  sure that
     # you have loaded a kernel SCSI driver for your SCSI adapter.

  I also tried using the network connection. I looked at the pixma.conf as 
  the best bet for the driver, but noticed that the printer is not 
  listening on port 8612.

  $ nmap 10.0.25.165

  Any suggestions?
