Yes I am a member of both lp and scanner groups.  The lines in messages.log
are for example:

I am wondering now whether this is a problem with a systemd service file
possibly?  The printer part works. Just the scanner that doesnt.
By the way there is a bug in cups awaiting the version 1.6.2 which I
"fixed" by removing the offending line in cupsd.conf as per:

https://bugs.archlinux.org/task/32768

I also tried with and without the file in /etc/udev/70-libsane.rules
containing:
ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="342b", MODE="0660",
GROUP="scanner",  ENV{libsane_matched}="yes"

Behaves the same with that included or not.
