Problems detecting scanner: brother dcp-j315w

skrotnisse · 04-26-2017, 09:40 AM

I've installed KDE Neon (based on Ubuntu 16.04 LTS (kernel 4.8.0-49)) and installed the drivers for Brother dcp-j315w. The printer works fine, but I cannot find the scanner with "scanimage -L" nor with "sane-find-scanner" I've got the following outputs:

Code:

As far as I can see I've installed every driver (+uninstalled and reinstalled several times...), I've added the brother printer to /lib/udev/rules.d/60-libsane.rules . Restarted the computer etc.

The scanner has previously worked very well with Debian, Slackware, Linux Mint, and Crunchbang.

Check that /etc/sane.d/dll.conf has an uncommented 'brother3' entry present. This should help with getting this device recognised.

skrotnisse · 04-26-2017, 10:34 PM

I have brother3 uncommented in /etc/sane.d/dll.conf. Still no success

Does your udev rule assign a group, and is the user a member of that group?

ferrari · 04-27-2017, 12:52 AM

Is the scanner detected if sane-find-scanner run as root?

Code:

sudo sane-find-scanner

Open a terminal and monitor kernel messages with

Code:

dmesg -wH

then plug in the multifunction device and capture the output.

skrotnisse · 04-27-2017, 01:52 AM

The output of

Code:

sudo sane-find scanner

is (I had to shorten the output, but I hope it includes necessary information):

Code:

  # 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.

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.
  # SANE has been built without libusb support. This may be a reason
  # for not detecting USB scanners. Read README for more details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

The output of

Code:

 dmesg -wH

is

See if the advice in this thread helps...

FWIW, I note that you mentioned this in your opening post

What does your udev rule look like? I note that there is a 'brother-udev-rule-type1-1.0.2-0.all.deb' package that needs to be installed to provide the appropriate rule automatically. Refer Scanner Setting file (deb package)...

I downloaded that rule to inspect if further...

Thank you for you time!
I still don't know what went wrong, but I think the problem was related to the distribution. Even if KDE Neon is based on Ubuntu they are probably not equivalent. I had no problem getting the scanner working in Linux Mint.
However, I learned a lot during my attempts

ferrari · 04-27-2017, 02:54 PM

Yes, any situation like this that forces you to get under the hood will make you learn!
