Bij mij werkt de DCPJ315W op 12.04 32bits naar behoren, printen & scannen
Add network scanner entry in a terminalscreen as superuser:
paul@paul-laptop:~$ brsaneconfig3 -a name=SCANNER model=DCP-J315W ip=192.168.1.108
Check the result:
paul@paul-laptop:~$ brsaneconfig3 -q | grep SCANNER
0 SCANNER "DCP-J315W" I:192.168.1.108
paul@paul-laptop:~$ sudo gedit /lib/udev/rules.d/40-libsane.rules
Add the following two lines to the end of the device list. (Before the line "# The following rule will disable ..."):
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
Misschien heb je er iets aan
