[sane-devel] Brother DCP-J315W

[David Brown]

Hi Guys,

I've used various versions of Ubuntu for some years now and every time I do
a fresh install I run into major problem getting my scanner to work
(Brother DCP-J315W).

Usually I get there after researching 3 hours and usually editing the
40-libsane.rules file which subsequently became 60-libsane1.rules and maybe
20-sane.hwdb.  Who knows - way too hard for the average user and only just
within my skills area.  Very frustrating and a real "go back to Windows"
moment.

Recently, I upgraded my old system to Ubuntu 24.04.2 and scanner worked
after the upgrade.  So far so good.  But then I did a fresh install of
U24.04.2 on a new external SSD and all hell broke loose.  No amount of
fixing or tweaking worked.  My scanner is bricked unless I boot into my old
OS.

I contacted Brother and they concluded that Ubuntu had changed something
and neither Ubuntu forums or Brother could work it out.  Neither are too
interested in supporting an old, possibly obsolete model.

Can you guys shed any light on what has changed or what I need to tweak to
get my scanner recognised?

Cheers
David
