I have Ubuntu 16.04 (upgraded from 14.04) and have installed a Brother DCP-7070DW multifunctional. I have installed all drivers already in 14.04 but did not get the scanner function working on this install. I did get it working on an earlier Ubuntu install, also 14.04. I would like to fix this now but unsure how. I tried the solution in Brother scanner not working in Ubuntu 16.04 though driver installed unsuccessfully.
$ dpkg -l | grep Brother
ii brscan-skey 0.2.4-1 amd64 Brother Linux scanner S-KEY tool
ii brscan3 0.2.11-4 amd64 Brother Scanner Driver
ii brscan4 0.4.4-1 amd64 Brother Scanner Driver
ii cupswrapperdcp7070dw:i386 2.0.4-2 i386 Brother DCP7070DW CUPS wrapper driver
ii dcp7070dwlpr:i386 2.1.0-1 i386 Brother DCP-7070DW LPR driver
ii printer-driver-brlaser 3-5~ubuntu1 amd64 printer driver for (some) Brother laser printers
ii printer-driver-ptouch 1.4-1 amd64 printer driver Brother P-touch label printers
The scanner is installed but probably configured incorrectly.
$ scanimage -L
device `brother4:bus3;dev2' is a Brother DCP-7070DW USB scanner
I installed gscan2pdf but when I run it I get:
*Error opening device: opening device 'brother4:bus3;dev2': Invalid argument
Simple scan sees the scanner but says: Unable to connect to scanner.
What can I do to tackle this issue?
