Brother DCP-7070DW

[vitozabal]

Hi, I have a problem with scanning on my Brother DCP-7070DWR, Ubuntu 14.04 via GUI software like xsane or simplescan

My printer connected via wifi. I have succesfully install printer and scanner Brother's drivers. Printing works just fine. But I can not scanning - xsane telling me "No devices available" (from root too)

Scanimage test show me all ok:

vito@vws:~$  scanimage -d test -T
scanimage: scanning image of size 157x196 pixels at 8 bits/pixel
scanimage: acquiring gray frame, 8 bits/sample

scanimage: stepped read, 15 bytes...     PASS
scanimage: stepped read, 7 bytes...     PASS
scanimage: stepped read, 3 bytes...     PASS

But sane find scanner shows me some pipe trouble:

vito@vws:~$ 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.

  # Not checking for parallel port scanners.


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

However, I run evaluated VueScan - and it scans perfectly out of the box. Please give me some ideas how to fix xsane working.

You probably need to tell the driver the IP address of the scanner.

Network scanner

See step 5.

Can you post output for

dpkg -l | grep -i brother

This should show the drivers you installed.

Good Luck

here is:

vito@vws:/opt/lampp/htdocs/qoot$ dpkg -l | grep -i brother
ii brgenml1cupswrapper 3.1.0-1 i386 Brother BrGenML1 CUPS wrapper driver
ii brgenml1lpr 3.1.0-1 i386 Brother BrGenML1 LPR driver
ii brscan-skey 0.2.4-1 i386 Brother Linux scanner S-KEY tool
ii brscan4 0.4.3-1 i386 Brother Scanner Driver
ii printer-driver-ptouch 1.3-8 i386 printer driver Brother P-touch label printers

Thank you

please note that installed VueScan scanning software works good (scans successfully), so seems it is not IP address issue. But xsane/simplescan does not work and this is a problem (cause it is a free software)

[vitozabal]

Solved.
Get scanner's IP Address by using the Menu button on the printer/scanner, select Network, then TCP / IP, then IP Address. Ping it:

brsaneconfig4 -p 192.168.0.107

not any answer in my case. So I set my scanner IP by brsaneconfig:

brsaneconfig4 -a name=DCP-7070DW model=DCP7070DW ip=192.168.0.107

Then restart computer and ping again. Ping now works fine and xsane detects scanner successfully.
