Title:
  Scanning works only as root after upgrade to 14.04 LTS, fixable by
  adding user to group lp

Status in simple-scan package in Ubuntu:
  Confirmed

Bug description:
  I have a Brother MFC-7420 printer/scanner combination device. It was
  working when I had Ubuntu 12.04 LTS installed. I have installed the
  Brother drivers from the Brother website (brscan2 version 0.2.5-1).

  When upgrading to Ubuntu 14.04 LTS scanning stopped working as a
  normal user, neither Simple Scan nor Xsane found the scanner. When
  launching as root, both were working (e.g. sudo simple-scan).

  The problem was related to the scanner device (/dev/usb/lp0) belonging
  to the group lp, with normal users having no access permissions to the
  device file. When I added my user account to the lp group, it solved
  the issue.

  Curiously, sane-find-scanner still cannot find my scanner, but
  scanimage -L works, as well as simple-scan and xsane.

  The same problem has been discussed here, concerning Ubuntu 13.10 (I'm running 14.04 LTS 64bit):
