Thanks for the prompt reply:

Thanks for the pointer to the documentation, I've found
http://ljm.home.xs4all.nl/SANE-faq.html#50 which looks most nearly 
relevant but not quite.

The equipment is EPSON-Stylus-CX5300 (according to the Printing tool),
but I get
[jeremy at home2006 ~]$ scanimage -L
device `epson2:libusb:003:002' is a Epson CX5400 flatbed scanner

Here is exactly what I did with scanimage:

[jeremy at home2006 ~]$ scanimage >image.pnm
scanimage: sane_start: Invalid argument

[jeremy at home2006 ~]$ scanimage -d epson2:libusb:003:002 >image.pnm
scanimage: sane_start: Invalid argument

In xsane I just started it up and clicked "Scan"

I can't think of any further relevant details but happy to provide them 
if I know exactly what further details are required

Thanks,

Jeremy Dawson
